我在 var 中遇到了空间问题。原因是 snap 文件，所以我尝试了一些方法来删除它们，但问题仍然相同。我尝试执行文件，但它对我来说不起作用 -https://www.linuxuprising.com/2019/04/how-to-remove-old-snap-versions-to-free.html. 找到一种方法，用一行代码将其删除：
snap list --all | while read snapname ver rev trk pub notes; do if [[ $notes = *disabled* ]]; then snap remove "$snapname" --revision="$rev"; fi; done
这会删除一些旧的 snap 版本，但问题仍然存在：
