Systemd
Udev、libpam-systemd、systemd-sysv 和 systemd 依賴項錯誤導致無法使用
再次錯誤下載pop-desktop後，udev和systemd出現依賴錯誤，導致無法使用apt。當我執行 sudo apt upgrade 時，出現此錯誤：
user@computer:~$ sudo apt upgrade Reading package lists... Done Building dependency tree... Done Reading state information... Done You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: libpam-systemd : Depends: systemd (= 249.11-0ubuntu3.1) systemd-sysv : Depends: systemd (= 249.11-0ubuntu3.1) udev : Breaks: systemd (< 249.11-0ubuntu3.1) Breaks: systemd:i386 (< 249.11-0ubuntu3.1) E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).當我嘗試 sudo apt –fix-broken install 時：

我試過 sudo dpkg –configure -a 它回來了：

我在 Pop_Os 上遇到了同樣的問題！22.04 LTS 和這裡的答案https://askubuntu.com/questions/146150/unable-to-fix-broken-packages-with-sudo-apt-get-install-f
為我解決了這個問題。我從該文件中刪除了 udev 條目，執行了成功完成的 apt 升級。
然後我確認 udev 回到了文件中，到目前為止一切似乎都很好，並且現在通過終端或流行商店進行更新，但我不能 100% 確定這是否會有任何負面的後續問題。
在做任何事情之前一定要備份文件以防萬一！
