我收到一个弹出窗口，上面写着“Firefox 有更新。请确保它未在运行”。因此，我确保 Firefox 未在运行，然后执行以下操作：
Wizard Earth:snap refresh firefox
error: cannot perform the following tasks:
- Run configure hook of "firefox" snap if present (run hook "configure": /snap/firefox/1993/snap/command-chain/hooks-configure-desktop: line 34: cannot create temp file for here-document: No such file or directory)
Wizard Earth:
因此我开始探索：
Wizard Earth:ll /snap/firefox/
total 8
drwxr-xr-x 3 root root 4096 Oct 24 06:21 ./
drwxr-xr-x 21 root root 4096 Oct 14 11:16 ../

lrwxrwxrwx 1 root root 4 Oct 24 06:21 current -> 1943/
Wizard Earth:
好的，所以没有 1993，但是 1943 下有一个 hooks-configure-desktop！
Wizard Earth:ls /snap/firefox/1943/snap/command-chain/hooks-configure-desktop

Wizard Earth:
它可以运行，但问题仍然存在。
由于该脚本存在于 1943 年，而没有 1993 年，我想我会尝试对其进行符号链接：
Wizard Earth:ln -s 1943 1993
Wizard Earth:snap refresh firefox
error: cannot perform the following tasks:
- Mount snap "firefox" (1993) (systemctl command [start snap-firefox-1993.mount] failed with exit status 1: Job failed. See "journalctl -xe" for details.
)
Wizard Earth:ll
total 8
drwxr-xr-x 3 root root 4096 Oct 24 06:34 ./
drwxr-xr-x 21 root root 4096 Oct 14 11:16 ../
drwxr-xr-x 7 root root 201 Oct 7 13:20 1943/
lrwxrwxrwx 1 root root 4 Oct 24 06:28 current -> 1943/
Wizard Earth:
因此它无法启动 snap-firefox-1993.mount，因为在某个过程中它删除了 1993！Firefox 是否需要挂载？
然后我想，“我想知道如果我把 1943 -> 1993 放进去会发生什么”。这就是事情变得奇怪的地方：
Wizard Earth:mv 1943 1993
mv: cannot move '1943' to '1993': Device or resource busy
Wizard Earth:lsof 1943
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
Output information may be incomplete.
lsof: WARNING: can't stat() fuse.portal file system /run/user/1000/doc

Wizard Earth:
也许是抄袭？
Wizard Earth:cp -rp 1943 1993
Wizard Earth:snap refresh firefox

Wizard Earth:ls

Wizard Earth:
好的，删除并重新安装怎么样？
Wizard Earth:snap remove firefox

太棒了！现在我再也无法运行 Firefox 了！也许可以重新安装？
