在 POP_OS 中刪除滑鼠墊依賴是否安全？
注意：最初在Ask Ubuntu上發布了問題，他們親切地指向這個 StackExchange，因為它更適合非官方的 Ubuntu 衍生產品。
背景資料。
目前執行 POP_OS 20.04
在作業系統版本為 18.10 時安裝
mousepad文本編輯器，並在升級到後續作業系統版本期間將其用作預設文本編輯器。我現在正在執行 Pop_OS 20.04 LTS，發現它gedit可以很好地用於基本文本編輯。現在準備刪除mousepad（如果安全且可能，連同任何不必要的依賴項）。已設置
gedit為預設文本編輯器。首次嘗試
mousepad通過 POP Shop 解除安裝 0.4.2（deb 版本）出現以下錯誤，解除安裝“滑鼠墊”失敗
This may have been caused by external or manually compiled software. The following packages have unmet dependencies: gir1.2-gtksource-3.0: Depends: libgtksourceview-3.0-1 (>= 3.23.90) but it is not going to be installed使用命令行查看刪除滑鼠墊（僅）給出以下內容，
sudo apt remove mousepad
0 升級，0 新安裝，1 刪除和 0 未升級。
此操作後，將釋放 1,612 kB 磁碟空間。（暫時中止）
然後查看

mousepad(1,612 kB) 就可以了，但肯定想刪除 787 MB 的 324 顯然不再需要的依賴項。但是，鑑於返回的資訊量不夠，沒有足夠的知識和經驗告訴終端是 - 請刪除這些。問題：在不引起災難性問題的情況下刪除這些依賴項真的基本上安全嗎？如果沒有，我很想知道這裡發生了什麼……
到目前為止，已經了解 autoremove 命令只會刪除不再需要的依賴項（可以安全解除安裝），但這種假設可能不正確。
sudo apt autoremove不會破壞任何東西或刪除其他包所需的依賴項。使用滑鼠墊的額外參數執行它，
sudo apt autoremove mousepad只會將滑鼠墊和它的唯一依賴項添加到要刪除的孤兒列表中。
