Lubuntu 20.04で日本語入力

Lubuntu 20.04 は少し古い （・・・現時点（2023年）ではかなり古い？）Distroで日本語入力の設定（fcitx-mozc）で上手く動かすことができない．おそらく繰り返してupdate/upgradeしていたが，fcitxは開発が止まっているため，不具合が出ているかもしれない・・（この記事によれば）

上記の記事に従って fcitxではなくfcitx5とfcitx5-mozcをインストールしたら上手く日本語入力ができるようになった

実施手順：

下記のコマンドで表示される古いfcitx関連パッケージをすべて削除（apt remove）

% apt search "^fcitx" | grep installed

その後，上記の記事の手順に従ってfcitx5-mozcをインストール

% sudo add-apt-repository ppa:ikuya-fruitsbasket/fcitx5

% sudo apt install fcitx5 fcitx5-mozc

後は下記のようにmozcをInput Methodに追加しCtrl + Spaceで入力を切り替えれば日本語入力できるようになる

Wireshark does not work with Tightvncserver

Using kali linux on raspberry pi 4 but wireshark does not work with tightvnc server...  According to this issue report, it's the issue with Qt 

Version of Kali linux I'm using:

$ cat /etc/os-release                       

PRETTY_NAME="Kali GNU/Linux Rolling"

NAME="Kali GNU/Linux"

VERSION="2023.1"

VERSION_ID="2023.1"

VERSION_CODENAME="kali-rolling"

ID=kali

ID_LIKE=debian

HOME_URL="https://www.kali.org/"

SUPPORT_URL="https://forums.kali.org/"

BUG_REPORT_URL="https://bugs.kali.org/"

ANSI_COLOR="1;31"

To fix this issue, changing from "tightvnc" to "tigervnc-standalone-server" and confirmed that the issue is actually fixed

Steps to install and my config:

1. Fist install "tigervnc-standalone-server"

$ sudo apt install tighervnc-standalone-server

After this step, "update-alternatives" will change the link of "vncserver" from "/usr/bin/tightvncserver" to "/usr/bin/tigervncserver"

2. Generate password

$ vncpasswd

3. Then create "/etc/systemd/system/vnc-server.service" file as below:

$ cat /etc/systemd/system/vnc-server.service
[Unit]
Description=VNC Server

[Service]
ExecStart = sudo -u kali vncserver -geometry 1440x900 :1 -localhost=0
ExecStop = sudo -u kali vncserver -kill :1
Type = forking

[Install]
WantedBy = multi-user.target

After this just enable/start the service...

Note: "-localhost=0" option is intentionally used in my environment (not secured) because I just want to directly connect to the VNC service, without using a SSH tunnel. By default this option of "tigervncserver" is "-localhost=1"

Dbus error after running Eclipse Oxygen

Error when running Eclipse Oxygen (with CDT) on lubuntu 20.04:

GLib-GIO-CRITICAL **: 16:15:43.425: g_dbus_proxy_new: assertion 'G_IS_DBUS_CONNECTION (connection)' failed

Fixed the sympthon by following command (see: here):

sudo apt purge fcitx-module-dbus

Import OVA which is created by VMWare to VirtualBox

Notes about the problem I had when trying to import OVA created by VMWare to VirtualBox...

My environment: 

• Windows 10 pro + VirtualBox v7.0 
• VirtualBox downgraded to 6.1.26 due to this issue with Wayland
• Still not fixed with Wayland on old linux guest machine (kernel 2.x)

Failed to import OVA file, error when trying import OVA file (exported by VMWare) to VirtualBox:  

• VBOX_E_INVALID_OBJECT_STATE (0x80bb0007)

OVA file is just a tar file, so extracted it using 7z, we can see these 3 files:

• vm-disk1.vmdk: Virtual Disk file
• vm.mf: checksum data
• vm.ovf: OVF file, VM definition file

Use "qemu-img" to check "vm-disk1.vmdk" (need to install qemu tool to Windows ):

> qemu-img info vm-disk1.vmdk
image: vm-disk1.vmdk
file format: vmdk
virtual size: 22 GiB (23667847168 bytes)
disk size: 316 MiB
cluster_size: 65536
Format specific information:
    cid: 1377153543
    parent cid: 4294967295
    create type: streamOptimized
    extents:
        [0]:
            compressed: true
            virtual size: 23667847168
            filename: vm-disk1.vmdk
            cluster size: 65536
            format:

Probably  VirtualBox could not handle the "streamOptimized" type or compressed vmdk disk image format. 

Tried  use "qemu-img" to convert it to non-compressed disk image:

> qemu-img convert -f vmdk vm-disk1.vmdk -O vmdk vm-disk1-decompressed.vmdk
    
> qemu-img info vm-disk1-decompressed.vmdk
image: vm-disk1-decompressed.vmdk
file format: vmdk
virtual size: 22 GiB (23667847168 bytes)
disk size: 709 MiB
cluster_size: 65536
Format specific information:
    cid: 3421777080
    parent cid: 4294967295
    create type: monolithicSparse
    extents:
        [0]:
            virtual size: 23667847168
            filename: vm-disk1-decompressed.vmdk
            cluster size: 65536
            format:

Ok, now it is "monolithicSparse" and not-compressed disk image type.

Because we just created a new disk, old checksum in file "vm.mf" cannot be used so just delete this file before trying to import again

Replace the  original "vm-disk1.vmdk" with "vm-disk1-decompressed.vmdk"(or edit the "vm.ovf" to make it point to "vm-disk1-decompressed.vmdk", no need to correct the disk size information in this case)

Now try to import again "vm.ovf" and we should be able to import it to VirtualBox. After this step, we can modify the config of the imported VM (cpu numer, memory size, etc., just check the "vm.ovf" and try to set the same config)

After this step, we can run the imported virtual machine, but if you see the error No bootable medium found! System halted , you should enable the "Enable EFI" config:

Done.

xargsコマンドのオプション -n[number]

findコマンドとxargsの組み合わせで，-n[number]オプションの使用のメモ．．． xargsコマンドに-n1を指定すると1つの引数だけを指定したコマンド（下記のecho）に渡すようになる

$ ls
fileA  fileB  fileC  fileD
$ find . -type f | xargs echo
./fileA ./fileC ./fileD ./fileB
$ find . -type f | xargs -n1  echo
./fileA
./fileC
./fileD
./fileB
$

Bring back taskbar to the default one after accidentally changed it in Lubuntu

Termux - Buidl and Install OpenCV (opencv-python) / opencv ビルド & インストール

Build and install OpenCV in Termux

1. Install "python"

    % pkg install python

2. Try to install "numpy"

    2.1 Prepare "libm.so"

        Check if you have libm in $PREFIX/lib

            % ls -al $PREFIX/lib | grep libm

        

        If you could not find "libm.so" in $PREFIX/lib, bring it from /system/lib to $PREFIX/lib

        (this step is needed for building opencv later on also)

            % ln -s /system/lib/libm.so $PREFIX/lib/libm.so

    2.2 Install "numpy"

        % LDFLAGS="-lm -lcompiler_rt" pip install --no-cache-dir numpy

        

        Note: without "LDFLAGS=..." part, you might get the following error

Python 3.8.0 (default, Dec  5 2019, 10:21:08)

    2.3 Test if we can import numpy to make sure it's installed correctly

3. Build "opencv"

    3.1 Install some libraries
        % pkg install cmake pkg-config libjpeg-turbo libpng
 
    3.2 Clone source code of opencv
        % cd storage/external-1
        % git clone https://github.com/opencv/opencv.git
        % cd opencv
        % git checkout -b tag4.2.0 refs/tags/4.2.0

        Then apply the following changes to opencv/modules/python/CMakeLists.txt

 
    3.3 Run cmake to config before building
        % cd opencv
        % mkdir build && cd build

        % LDFLAGS=" -L$PREFIX/lib/ -llog -lm -lpython3.8 " \
        cmake \
        -DOPENCV_SKIP_PYTHON_LOADER=OFF \
        -DCMAKE_BUILD_TYPE=RELEASE \
        -DCMAKE_INSTALL_PREFIX=$PREFIX \
        -DOPENCV_ENABLE_NONFREE:BOOL=ON \
        -DBUILD_opencv_python3:BOOL=ON \
        -DBUILD_opencv_python2:BOOL=OFF \
        -DPYTHON_EXECUTABLE=$PREFIX/bin/python3 \
        -DPYTHON_DEFAULT_EXECUTABLE=$PREFIX/bin/python3 \
        -DPYTHON3_EXECUTABLE=$PREFIX/bin/python3 \
        -DPYTHON3_INCLUDE_DIR=/$PREFIX/include/python3.8 \
        -DPYTHON3_INCLUDE_DIR2=/$PREFIX/include/python3.8 \
        -DPYTHON3_LIBRARIES=$PREFIX/lib/python3.8.so \
        -DPYTHON3_INCLUDE_PATH=$PREFIX/include/python3.8 \
        -DPYTHON3_LIBRARY=$PREFIX/lib/libpython3.8.so \
        -DPYTHON3LIBS_VERSION_STRING=3.8 \
        -DPYTHON3_PACKAGES_PATH=$PREFIX/lib/python3.8/site-packages \
        -DPYTHON3_NUMPY_INCLUDE_DIRS=$PREFIX/lib/python3.8/site-packages/numpy/core/include \
        -DPYTHON3_NUMPY_VERSION=1.18.2\
        -DBUILD_JAVA=OFF \
        -DBUILD_ANDROID_PROJECTS=OFF \
        -DBUILD_ANDROID_EXAMPLES=OFF \
        -DWITH_QT=OFF \
        -DWITH_GTK=OFF \
        -DWITH_TEST=OFF \
        -DBUILD_TESTS=OFF \
        -DBUILD_EXAMPLES=OFF ..

    After the step above, you should get the following result, check if "python3" is included in "to be built" module list...

        After all these steps, you should be able to "import cv2" in Python

Termux - Pillow installation / Pillow インストール

Install dependencies:
apt install libjpeg-turbo libjpeg-turbo-progs
apt install ndk-sysroot  --> 180 MB
apt install python clang fftw libcrypt libzmq
apt install freetype libpng pkg-config

pip install wheel
pip install pillow

You might need to upgrade pip first, then do the following step:
pip install --upgrade pip

If there's a build error, we can try the following also:

LDFLAGS="-L/system/lib/" CFLAGS="-I/data/data/com.termux/files/usr/include/" pip install wheel
LDFLAGS="-L/system/lib/" CFLAGS="-I/data/data/com.termux/files/usr/include/" pip install pillow

Ubuntu Android sdk install memo

Androidの開発環境を lubuntuに入れる。
Eclipseはインストールする必要がなく、"adt-bundle-linux-x86-20140321.zip"をGoogleからダウンロードし、unzipしたらeclipseとSdkが入っている。eclipseはそのまま実行すれば、すべてADTなどが入っている。

sdkをPATHに入れる.bashrc：

export PATH=${PATH}:~/.../sdk/tools
export PATH=${PATH}:~/.../sdk/platform-tools

Opengles emulator:

sudo apt-get install libgles2-mesa-dev

Ubuntu, Lubuntu 12.04 with VirtualBox

Proxy設定for apt-get：はapt.conf.dの中に設定ファイル（例えばここでは80proxy）を追加

% export http_proxy="http://x.x.x.x:8080"
% export ftp_proxy="..."
% export https_proxy="..."

% sudo vim /etc/apt/apt.conf.d/80proxy
Acqurire::http::proxy "http://x.x.x.x:8080";
Acqurire::https::proxy "http://x.x.x.x:8080";
Acqurire::ftp::proxy "http://x.x.x.x:8080";

これでProxyを通してupdateできる 上記はapt-get用のプロキシの設定で，システムのプロキシ設定は/etc/environmentファイルを編集して追加する．

/etc/environment

http_proxy=http:// myproxy.server.com:8080/ 
https_proxy=http:// myproxy.server.com:8080/
ftp_proxy=http:// myproxy.server.com:8080/
no_proxy="localhost,127.0.0.1,localaddress,.localdomain.com"

■ Install vim
$ sudo apt-get install vim

■ Google input method
$ sudo apt-get install ibus-mozc
$ ibus-setup # <- p="">

■ Build tools
$ sudo apt-get install build-essential
$ sudo apt-get install subversion git ssh
$ sudo apt-get install cmake cmake-gui

■ java SDKインストール

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update

$ sudo apt-get install oracle-java6-installer
$ sudo apt-get install oracle-java7-installer

○Java 6, 7の切り替えするには
$ sudo update-alternatives --config java

■ LaTeX
$ sudo apt-add-repository ppa:texlive-backports/ppa
$ sudo apt-get update

$ sudo apt-get install texlive-lang-cjk
$ sudo apt-get install texlive-fonts-recommended

ここまでで、texを使用できるが日本語のフォントがでない

○解決方法：
フォントmapの場所を調べ方
$ kpsewhich ptex-ipa.map
/usr/share/texlive/texmf-dist/fonts/map/dvipdfmx/jfontmaps/ptex-ipa.map

上のようにパスが通っていればOK。dvipdfmxでPDFを作成するときはフォント埋め込み指定する

$ dvipdfmx -f ptex-ipa.map Sample.dvi
$ acroread Sample.pdf　で確認

これで日本語のPDFを作成できる。しかし、xdvi、evinceでフォント化けている。

○xdviの設定を書き換える
$ fc-list | grep IPA -> フォントIPAがあるかどうかを確認、あれば下記のように実行
$ cd /etc/texmf/vfontmap.d
$ sudo cp 20xdvik-ja.map 20xdvik-ja.map.org

$ sudo vim 20xdvik-ja.map

@IPAMincho-Regular@

dm   JIS-H % NTT jTeX

@IPAGothic-Regular@
gbm  JIS-H % ASCII pTeX
gbmv JIS-V % ASCII pTeX
dg   JIS-H % NTT jTeX

$ sudo update-vfontmap
$ xdvi Sample.dvi で確認、これで日本語がちゃんと出ている

○evinceで日本語が出ない。poppler-dataパッケージがインストールされていないことが原因
$ sudo apt-get install poppler-data
$ evince Sample.pdf で確認、日本語OK

基本は、Ubuntu 10.04だけをサポートするが、他のバージョンも使用出来る事を確認した。（SDKのOSバージョンチェックのシェルを書き換えればOk）。仮想マシーンの構築はこのページを参照。

■SDKのインストール
このページから"ti-sdk-am335x-evm-x.x.x.x-Linux-x86-Install"ファイルをダウンロード。
実行すると、インストール先を聞いてくるので、下記Dirを指定

$HOME/ti-sdk-am335x-evm-...-linux-x86 (以降 $TI_SDK_PATH とする)

これで、SDKファイルが展開される。続いては、SDKのセットアップは下記の順番で行う

• ホストPCのUbuntuバージョンチェック
• ホストPCに必要なパッケージのインストール
• ターゲットファイル・システムインストール
• NFS設定
• TFTP設定
• Minicom設定
• U-boot設定
• ロードブードスクリプト作成

●１．SDK設定シェルの実行

$ cd $TI_SDK_PATH; ./setup.sh

ここでもし、Ubuntu 10.04を使用しなければエラーが出る。別のバージョンのubuntuにインストールしたい場合は、シェールスクリプトのOSバージョンチェックを書き換える必要がある。

●２．ホストPCに必要なパッケージインストール
下記のパッケージがホストPCになければ、自動的にインストールされる

• telnet
• menuconfig, kernel configuration tool
• mounting filesystem via nfs
• tftp
• minicom
• rebuild u-boot

手動でパッケージを事前にインストールしたい場合は下記を実行

$ sudo apt-get install xinetd tftpd nfs-kernel-server minicom build-essential libncurses5-dev uboot-mkimage autoconf automake

●３．ターゲットファイルシステムのインストールターゲットファイル・システムはデフォルトで下記の場所に作成される

$TI_SDK_PATH/targetNFS

●４．tftp設定
tftpの設定で、ホストPCのルートDirに "/tfptboot"が作成され、tftpの設定は"/etc/xinetd.d/tftp"に保存される

●５．minicom設定
Usb-to-Serialケーブルを使用する場合は、"/dev/ttyUSBx"、そうでない場合は"/dev/ttyS0"を指定する

●６．uboot設定

• ホストのIPアドレス確認
• カーネルロケーションの指定
  －TFTPを選択する場合は、"/tftpboot"のDirを適切に指定
  －SD cardを選択する場合は、SDカードの最初のパーティション（"boot"という名前）になる
• ファイル・システムの指定

■ PowerVR SGX SDKインストール [ページ１、ページ２]
BeagleBoneのハードウェア

• SOC : AM335x
• SGX Core : SGX530
• SGX Core rev. : 1.2.5
• SDK folder suffix : es8.x
• Max SGX Core Freq : 200 Mhz

●Graphic SDKのインストール：
SDKのインストール時、展開されたパッケージの中に既に"Graphic_SDK_setuplinux_[version].bin"が入っているので、これを実行すれば、Graphic SDKをインストールできる。

また、ウェブからGraphic SDKをダウンロードしてインストールする場合はこのページから"Graphics_SDK_setuplinux_4_08_00_01.bin"をダウンロードしてくる。

ターゲットボードに入れる必要があるのは、

• Kernel Modules
• Graphic SDK (examples, headers, lib ...)

■U-bootビルド

$ cd $TI_SDK_PATH
$ make u-boot-spl O=am335x

※O=am335xを指定すると、"$TI_SDK_PATH/board-support/u-boot-[version]/am335x"が作成され、make結果がここに格納される（推奨方法）

上の実行結果で、"u-boot.img"と"MLO"という２つのファイルが作成される（$TI_SDK_PATH/board-support/u-boot-[version]/am335xの中）、SDカードからブートする場合は、これらのファイルをSDカードに入れる必要がある。UART経由でロードしたい場合は、spl/u-boot-spl.binを利用する。

■SDカードのフォーマット
SDカードの作成で、ブート用のFat32、ファイル・システムのext3を作成する。作成方法は難しくないので省略（参考ページのre-partition SD cardの部分）


■Master Makefile

linux_install:

■ Lubuntuをインストール
$ sudo shutdown -h now
電源を抜いて、HDMI-Cape, HDMI-DVI変換をモニタにつないでから再度、電源を入れる

$ sudo apt-get -yV install lubuntu-core
$ sudo apt-get -yV install lubuntu-desktop
$ sudo apt-get -yV install lxde-common
$ sudo apt-get -yV install lxde-core
$ sudo apt-get -yV install lxde

これでlubuntuが無事画面に出ることを確認

Ubuntu 12.04 on VMware

Ubuntu 12.04 on vmware

■UI変わりすぎて使いにくい。なんとか戻すことにする

sudo apt-get install gdm
sudo apt-get install gnome-shell gnome-session-fallback

テキストログイン→GUIログインにしたい場合は
sudo start gdm

これでとりあえずOK

■日本語環境
sudo add-apt-repository ppa:japaneseteam/ppa
sudo apt-get update
sudo apt-get install ubuntu-defaults-ja

なんか日本語を対応させたいが、今英語バージョンで、もう一度ここから日本語バージョンのイメージをダウンロードし直すか、英語バージョンを日本語にするかを迷う。とりあえず後者で、手順はページの説明通り

Ubuntu 12.04 LTSの場合:

wget -q https://www.ubuntulinux.jp/ubuntu-ja-archive-keyring.gpg -O- | sudo apt-key add - wget -q https://www.ubuntulinux.jp/ubuntu-jp-ppa-keyring.gpg -O- | sudo apt-key add - sudo wget https://www.ubuntulinux.jp/sources.list.d/precise.list -O /etc/apt/sources.list.d/ubuntu-ja.list sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ubuntu-defaults-ja
sudo fontconfig-voodoo --force -s ja_JP

■Google日本語入力
sudo add-apt-repository ppa:ikoinoba/ppa
sudo apt-get update
sudo apt-get install ibus-mozc
sudo reboot

■ディレクトリを日本語にする
LANG=C xdg-user-dirs-gtk-update

■GVim
sudo apt-get install vim-gnome ubuntu-restricted-extras

■ Build
sudo apt-get install build-essential
sudo apt-get install svn git ssh
sudo apt-get install cmake
sudo apt-get install freeglut3 freeglut3-dev

make a small test:
g++ test.cpp -lGL -lglut -o test ※test.cppをリンクオプションの後に置くとエラー！

■Eclipseをインストールして、Proxy設定
Eclipseをインストールすると、設定ファイルなどはすべてrootが所有者になり、一般ユーザから設定を変更しても反映されない。Proxy設定はひとつの例。解決方法は
下記を /etc/eclipse.ini に追加すること

-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient
-Dhttp.proxyPort=8080
-Dhttp.proxyHost=XXX
-Dhttp.proxyUser=XXX
-Dhttp.proxyPassword=XXX
-Dhttp.nonProxyHosts=localhost|127.0.0.1

gmail pop imap 受信 （kuroboxから）

送信は先日できたが、こんどは受信。

use Mail::IMAPClient;
use IO::Socket::SSL;

２つのモジュールを入れて、受信できました。 問題があったのはメールのSubjectの部分で、エンコード、デコードしない場合、

=?ISO-2022-JP?B?Base64でエンコードされたSubject?=

になるので、まず、

Base64でエンコードされたSubjectの部分をDecodeして、そのあと ISO-2022-JPからutf8にDecodeすればよい。具体的には

use Encode;
use MIME::Base64;
$subject =~ s/=\?ISO-2022-JP\?B\?([A-Za-z0-9\+\/=]*)\?=/ decode_base64($1)/eg;
print decode("ISO-2022-JP", $subject), "\n";
