The following packages have unmet dependencies:
mono-complete : Depends: ca-certificates-mono (= 5.18.0.225-0xamarin1+ubuntu1804b1) but 5.16.0.179-0xamarin1+ubuntu1804b1 is installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
运行后apt --fix-broken install输出为：

我省略了大部分输出，因为它重复了相似的行，而且长度较长。
我已经尝试过清除/删除 mono 包，但是无法删除任何内容。我都不能用。apt upgrade我试过dpkg-reconfigure --force了mono-runtime-common，，，。mono-gacca-certificates-monomono-complete
我确实需要帮助。我该如何修复此问题？
答案1
尝试运行：（手动删除有问题的包）
$sudo mv /var/lib/dpkg/info/mono-gac.* /tmp
$sudo mv /var/lib/dpkg/info/mono-runtime-common.* /tmp
然后运行：
$sudo apt update && sudo apt install -f
答案2
尝试运行：
$sudo apt update && sudo apt install -f
如果您仍然遇到同样的问题，我猜您正在使用快照版本存储库，例如：
deb http://download.mono-project.com/repo/ubuntu bionic/snapshots/5.16.0.179 main
到修理它， 检查单一项目存储库并按照以下步骤操作：
清除所有 mono 包
$sudo apt remove --purge mono* libmono*禁用快照版本存储库并添加稳定存储库
#deb http://download.mono-project.com/repo/ubuntu bionic/snapshots/5.16.0.179 main deb http://download.mono-project.com/repo/ubuntu stable-bionic main更新你的 apt 并安装它
$sudo apt update $sudo apt install mono-complete mono-devel
希望这可以帮助
