最近我重启电脑后，电脑显示“磁盘空间不足警告”。我没有在意，结果磁盘空间/var/log不足，无法打开操作系统。所以我删除了 下的一些文件/var。
现在是 %95，但开始时仍然会给出警告。在我单击该警告中的“检查”后，您可以在图片中看到：
这是尺寸：

我不知道/var会用得很多。这就是为什么我只给了 5.7 GB。
最大的文件/var：
✘ canerveg@canerVegan ~ sudo du -h --max-depth=6 /var | sort -h|tail -n25
6,1M /var/cache/cracklib
6,4M /var/lib/gdm3

2,1G /var/lib/snapd/cache
4,3G /var/lib/snapd
4,9G /var/lib
5,1G /var
我想我可以安全地删除它：
2,1G /var/lib/snapd/cache
但为什么我必须删除这些？如果我知道它会涨得这么高，我可以增加尺寸。我应该增加尺寸吗，因为我有
/dev/nvme0n1p6 149G 34G 107G 25% /home
但缩小/调整大小会有风险。
这些是快照：

这里删除了旧版本： https://www.debugpoint.com/2021/03/clean-up-snap/
但我正在考虑彻底删除 snap。我可以随时从 snap 安装某些东西。你觉得怎么样？
软件更新程序正在下载一些更新，但它也会减少 /var 的大小。那么，我无法下载大于 5 gb 的任何 apt，因为我有 5 gb 的 /var？
我去了软件中心。单击已安装选项卡并删除了所有 Wine。有 3 个 Wine。我不知道我为什么要安装它们，或者也许安装了某个应用程序才能运行。
现在看起来好多了：

答案1
您所犯的错误与安装或使用 Snaps 无关。
您犯了一个典型的高级新用户错误：您进行了过度分区。
让我们看一下输出的片段：
/dev/nvme0n1p5 61G 6,9G 51G 12% /
/dev/nvme0n1p6 149G 34G 107G 25% /home
/dev/nvme0n1p4 5,6G 5,2G 143M 98% /var
Ubuntu 安装程序建议使用单个根分区（包括 /var 和 /home），结果将类似如下...
/dev/nvme0n1p4 217G 46G 171G 21% /
...并且您不会遇到任何有关完整分区的问题。
备份您的数据。重新分区以符合您的实际用途。重新安装。
