Ubuntu：bash：無法為此處文件創建臨時文件：設備上沒有剩餘空間

文件名選項卡完成後，我收到來自 bash 的錯誤 No space left on device。

正如在類似問題上所建議的那樣，當我試圖找出佔用我空間的東西時，我對 df -ah 結果感到困惑。我的電腦有 220GB 磁碟，似乎只使用了 66GB。

哪裡有問題？var/lib 中有很多 docker 鏡像？我應該把它們搬到別的地方嗎？

好吧，看看名單。您擁有的基本分區是以下兩個：

Filesystem      Size  Used Avail Use% Mounted on
/dev/nvme0n1p7   34G   32G     0 100% /
/dev/nvme0n1p9  173G   16G  149G  10% /home

即，您有一個單獨/home的 ~170 GB，但其他所有內容（包括/var）都在 中/，並且只有 34 GB。

重新分區已安裝的系統可能很困難（除非您使用的是 LVM，但您不是），但您可以嘗試查看是否有一些可以移動到的大型數據集/home，例如那些圖像。您還可以執行從/var/whatever到的符號連結，例如/home/var/whatever, （或類似的綁定掛載），以便數據在 . 下的預期位置仍然可見/var。
