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

在当前安装的系统上修复软件包

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

如果您真的想升级到非 LTS 9 个月支持的版本（比如对下一个 LTS 进行许多不必要的升级，例如：20.04 LTS ? 20.10 ? 21.04 ? 21.10 ? 22.04 LTS），然后允许这样的升级过程并运行它支持的正确方法

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 - 首先是 20.04 LTS ？20.10 和 20.10 秒？21.04。对于后者，您可能需要提供额外的-d选项。
