我通过 PPA 安装了 TeXLive 2016，并使用了以下命令-
sudo add-apt-repository ppa:jonathonf/texlive
sudo apt update
sudo apt install texlive-full
由于某些原因，我尝试删除它，但无法删除。后来，我通过以下链接从官方网站安装了 TeXLive通过互联网安装 TeX Live。我使用了以下命令-
ravi@home:~/Downloads/install-tl-20180527$ sudo ./install-tl
现在，我可以在 Ubuntu 14.04 LTS 上使用 TeXLive 2018。Texmaker 4.1 (compiled with Qt 4.8.4 and Poppler 0.24.3)但是，我的 Ubuntu 显示以下错误-
看来 TeXLive2016 是罪魁祸首。我用过，sudo apt-get purge texlive*但没用。请参见下文-

请问有什么解决方法吗？
答案1
你应该使用命令以正确的方式删除 PPA ppa-purge。它会将软件包降级到官方存储库中的版本，然后才会从/etc/apt/sources.list.d/。
您需要运行的命令如下：
#sudo add-apt-repository ppa:jonathonf/texlive # add you PPA again if removed
sudo apt-get install ppa-purge # install ppa-purge
sudo ppa-purge ppa:jonathonf/texlive # downgrade packages
然后使用以下命令安装 TeXLive 2018：
cd ~/Downloads/install-tl-20180527
sudo ./install-tl
