在我的Xenial系统上，我可以从Universe存储库安装unity-tweak-tool ，它可以正常工作。
因此，我建议清除其PPA并从存储库安装版本
sudo apt-get update sudo apt-get install ppa-purge sudo add-apt-repository main # add main repository for sure sudo add-apt-repository universe # add universe sudo add-apt-repository multiverse # add multiverse sudo add-apt-repository restricted # add restricted sudo add-apt-repository -r ppa:upubuntu-com/gtk3 # to fix apt-get update sudo ppa-purge ppa:freyja-dev/unity-tweak-tool-daily sudo apt-get update sudo apt-get upgrade sudo apt-get install -f sudo dpkg --configure -a sudo apt-get install unity-tweak-tool
如果所有这些步骤都无法帮助尝试从软件和更新切换到其他Ubuntu镜像。
您也可以尝试aptitude （可以使用sudo apt-get install aptitude ）
sudo aptitude install unity-tweak-tool
