跑sudo apt-get purge chromium-browser->不再添加铬。
然后：
wget http://archive.ubuntu.com/ubuntu/pool/universe/c/chromium-browser/chromium-browser_80.0.3987.163-0ubuntu1_amd64.deb -O /tmp/chrome.deb
sudo apt install -y --allow-downgrades /tmp/chrome.deb
但是当我运行chromium-browser --version时
我得到：
`Chromium 85.0.4183.102 snap`
这是安装日志：

我需要版本80才能在python中生成一些pdf脚本。运行脚本后，它失败，导致Chrome无法启动：异常退出。 我不知道为什么会发生这种情况或如何解决它。
