在最近的一次系统更新后，Snap 出现故障。例如，Telegram 桌面停止工作。我设法删除了 Telegram，但无法重新安装。原因在于 core22 模块损坏：
error: cannot perform the following tasks:
- Run configure hook of "telegram-desktop" snap if present (run hook "configure": cannot locate base snap core22: No such file or directory)
我尝试删除 core22 来修复这个问题，但是没有效果：
error: cannot perform the following tasks:
- Remove data for snap "core22" (522) (failed to remove snap "core22" base directory: remove /var/snap/core22: directory not empty)
我也无法修复它。我试过了sudo snap refresh core22 --edge，但是没有用：
error: cannot refresh "core22": refreshing disabled snap "core22" not supported
尝试启用 core22 但sudo snap enable core22失败：
error: cannot perform the following tasks:
- Setup snap "core22" (522) security profiles (cannot find installed snap "core22" at revision 522: missing file /snap/core22/522/meta/snap.yaml)

有没有办法修复，core22而无需在系统上完全重新安装 snap？谢谢
更新：添加了有关删除尝试的信息。更新 2：添加了ls -la /var/snap/core22
答案1
编辑：抱歉，我显然没有看到你已经尝试过
我可以通过刷新测试频道，然后刷新回稳定频道来解决这个问题
所以，我先跑
$ sudo snap refresh --beta core22
进而
$ sudo snap refresh --stable core22
然后安装程序返回了预期的行为
答案2
最后我找到了一个解决方案。事实上，如果我们回顾一下我在原始消息中发布的错误消息，这只是表面上的：
sudo rm -rf /var/snap/core22sudo snap remove core22sudo snap install core22
