我正在尝试删除 Ubuntu 22.10 上的 snap “firefox”。不幸的是，一个错误阻止了该任务的完成。

当我调用 Firefox 时，它正确启动。此时，我尝试像这样删除 snap firefox：
$ snap remove --purge firefox
但它不想这样做：
error: cannot perform the following tasks:
- Remove data for snap 'firefox' (1969) (unlinkat /var/snap/firefox/common/host-hunspell/en_US.aff: read-only file system)
我找到了这个有帮助的问题所以，这就是我所做的：
