鉴于Jitsi无法安装很好apt桌面客户端目前怎么样已安装？
上面提到了使用不稳定的 repo。
这些指示不适用于至少另一个：
Jitsi Download Development Documentation Support and Custom Development要使用我们的 debian/ubuntu 稳定存储库：
将 Jitsi 存储库密钥安装到您的系统上
wget -qO-https://download.jitsi.org/jitsi-key.gpg.key| sudo apt-key 添加 -
使用存储库创建 sources.list.d 文件
sudo sh -c “回显'debhttps://download.jitsi.org稳定/'> /etc/apt/sources.list.d/jitsi-stable.list”
更新你的包裹清单
sudo apt-get -y 更新
安装 Jitsi
sudo apt-get -y 安装 jitsi
添加两个存储库：
nicholas $
nicholas $ wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add -
OK
nicholas $
nicholas $ sudo sh -c "echo 'deb https://download.jitsi.org stable/' > /etc/apt/sources.list.d/jitsi-stable.list"
nicholas $
nicholas $ sudo sh -c "echo 'deb https://download.jitsi.org unstable/' > /etc/apt/sources.list.d/jitsi-unstable.list"
nicholas $
注释掉稳定的 repo 并更新：
nicholas $
nicholas $ cat /etc/apt/sources.list.d/jitsi-stable.list
#deb https://download.jitsi.org stable/
nicholas $
nicholas $ sudo apt update

然后未满足依赖项。哦，不稳定的仓库：

nicholas $ cat /etc/apt/sources.list.d/jitsi-unstable.list
deb https://download.jitsi.org unstable/
nicholas $
https://desktop.jitsi.org/Main/DebianRepository.html

nicholas $
nicholas $ sudo add-apt-repository universe
'universe' distribution component is already enabled for all sources.
nicholas $
nicholas $ sudo add-apt-repository multiverse

答案1
Jitsi Desktop（以前称为 SIP Communicator）的开发于 2017 年停止。它仍然是一个业余项目（来源) 并删除 Jitsi Meet 等其他项目的代码。因此，如果您真的想使用 Jitsi Desktop，请考虑使用免费的 Ubuntu 16.04 EMS (来源) 以及到 2024 年的选项。说到较新的 Ubuntu 版本：
Ubuntu 18.04 LTS
sudo apt install openjdk-8-jre libavcodec-extra libavfilter-extra libappindicator1
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64:/usr/lib/jvm/java-8-openjdk-i386/jre/lib/i386
wget download.jitsi.org/unstable/jitsi-archive-keyring_1.0.1_all.deb
sudo dpkg --install ./jitsi-archive-keyring_1.0.1_all.deb
wget download.jitsi.org/unstable/jitsi_2.11.5624-1_amd64.deb
sudo dpkg --install ./jitsi_2.11.5624-1_amd64.deb
jitsi --debug
我还没有测试如果安装了默认 JRE（即 Java 11）会发生什么。如果遇到问题，请sudo update-alternatives --config java更改为 Java 8。
Ubuntu 20.04 LTS
与 Ubuntu 18.04 LTS 的步骤相同，但还有一件事：
a) H.264 视频支持：不需要
您不需要 FFmpeg 的依赖项，因为那些只是受到推崇的库。不幸的是，Debian 控制文件是错误的，它将这些依赖项声明为必需的。因此，要运行 Jitsi Desktop编辑该文件...
b) H.264 视频支持：必需
如果您需要 H.264 视频编解码器（或 AMR-WB 音频编解码器），您必须下载jitsi-lgpl-依赖项并自行编译 Jitsi Desktop：
sudo apt install build-essential openjdk-8-jdk ant libavcodec-extra libavfilter-extra libappindicator1
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
# optionally (if another Java was installed, change to Java 8)
sudo update-alternatives --config javac
sudo update-alternatives --config java
# optionally (when you have to re-build Jitsi Desktop)
rm -rf ~/.m2
wget github.com/jitsi/jitsi/archive/3ebd5dfac749e0677377dbc8643dfbbbf4b450fa.tar.gz
tar -xf 3ebd5dfac749e0677377dbc8643dfbbbf4b450fa.tar.gz
cd ./jitsi/
# replace the following file:
# ./lib/installer-exclude/jitsi-lgpl-dependencies-1.2-1-gfc49658.jar
ant make
ant -Dargs="--debug" run
由于 Jitsi Desktop 的头部未经测试，编译错误随时可能发生。然后，在这里发表评论，我会看看哪里出了问题。
