我正在升级我的发行版。但在升级过程中，我遇到了这样的包失败错误。我尝试了所有方法，但找不到任何解决方案。你有什么建议吗？

You might want to run 'apt --fix-broken install' to correct these.

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).enter code here
答案1
修复当前安装的系统上的软件包
sudo apt --fix-broken install
sudo apt-get update
sudo apt-get install aptitude
sudo aptitude safe-upgrade
sudo aptitude upgrade
sudo aptitude dist-upgrade
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt --fix-broken install
sudo dpkg --configure -a
如果你确实想升级到非 LTS 9 个月的支持版本（比如说有很多不必要的升级到下一个 LTS，如：20.04 LTS → 20.10 → 21.04 →21.10→22.04 长期支持），然后允许此类升级过程并使用支持的正确方法运行它
sudo rm /etc/apt/preferences.d/pin-focal
sudo sed -i "s/^Prompt=lts/Prompt=normal/" /etc/update-manager/release-upgrades
sudo sed -i "s/^Prompt=never/Prompt=normal/" /etc/update-manager/release-upgrades
update-manager -c # in GUI or
# sudo do-release-upgrade # in terminal
注意：最后一个命令应该运行两次 - 第一次针对 20.04 LTS → 20.10，第二次针对 20.10 → 21.04。对于后者，您可能需要提供额外的-d选项。
