Snap 丢失。我想重新安装，但似乎无法先移除它们才能重新安装。我该如何修复？

答案1
你可以刷新如果您遇到类似以下错误
snap "core18" has no updates available
您可以通过暂时切换到边缘跟踪分支来强制刷新
snap refresh core18 --edge
然后，当问题解决后，将其切换回稳定的跟踪分支
snap refresh core18 --stable
答案2
删除所有依赖项允许删除 core18，然后重新安装。这并不像我想象的那么混乱。
2020 年 2 月 29 日之后的 Chromium 配置丢失了。我特意备份了 ~/.config/chromium，但该目录似乎只包含截至该日期的配置。
