發布升級後 apt 建議刪除 python2.7 和 3.6

在經歷了update, upgrade, dist-upgrade, dist-release-upgrade, 很多安裝失敗的問題之後，我設法修復了這些問題（顯然）並且到目前為止升級進展順利。

現在它已更新，重新啟動，但仍然有任何apt命令建議我刪除“未使用”的包，例如 python2.7 和其他包：

在刪除 Python2.7 後，我聽說過損壞的系統。

但是，當我執行“python3”時，它會打開 Python 3.8.10 CLI。

autoremove上述包裹安全嗎？

我執行 Ubuntu Server 20.04.3 LTS。

在 Ubuntu 20.04 上，python2.7 已移至universe儲存庫。該系統使用 python3.8 版本（請參閱python3 -V），因此您可以安全地刪除它。
