许多流程无法完成。
通常，除非我关闭所有其他应用程序，否则无法在一个应用程序中进行保存。
我删除了很多软件，还在终端中运行了所有我能在 Google 上搜索到的东西！输出粘贴如下：
（我最后也检查了 inode）

答案1
最快的方法之一就是删除不需要的大型旧快照。默认情况下，快照会保留当前和旧版本的应用程序，以防出现问题，这样您就可以回滚。
我注意到您安装了 LibreOffice 的多个修订版本，它相当大（1.1GB）。
/dev/loop36 1.1G 1.1G 0 100% /snap/libreoffice/272
/dev/loop42 1.1G 1.1G 0 100% /snap/libreoffice/275
使用以下命令删除旧的：
sudo snap remove libreoffice --revision=272
然后我会sudo apt install ncdu运行，ncdu ~它会显示哪些内容占用了你的主目录的空间。你可能有大量的下载内容或其他文件需要清理。
答案2
我按照下面的建议运行了 ncdu，发现
.thunderbird 占用了 24.7 GiB——几乎占了我一半的磁盘空间。
我需要删除旧电子邮件（它不允许我压缩文件夹，因为没有足够的磁盘空间来执行此操作），否则放弃我本地保存的电子邮件并找出如何删除 .thunderbird - 我认为这是 Thunderbird Mail 用来保存电子邮件的文件夹 - 因为我不需要旧电子邮件的本地副本。
