Package mc is not available, but is referred to by another package. This may mean
that the package is missing, has been obsoleted, or is only available
from another source However the following packages replace it:  
  mc-data
E: Package 'mc' has no installation candidate

结果命令 dkpg

$ dpkg -l mc*

我不知道该如何修复。您可能知道吗？

答案1

我检查源代码https://mirror.yandex.ru/ubuntu/dists/focal/universe/ 找不到包 mc

https://mirror.yandex.ru/ubuntu/dists/focal/universe/binary-i386/Packages.gz

但发现

https://mirror.yandex.ru/ubuntu/dists/focal/universe/binary-amd64/Packages.gz

这意味着该软件包不适用于 x86 架构，但可用于 x64。

如果需要安装“mc”，需要从以下位置下载https://launchpad.net

cd /tmp/
sudo apt remove mc-data
wget http://launchpadlibrarian.net/448485168/mc-data_4.8.23-1_all.deb
wget http://launchpadlibrarian.net/448485186/mc_4.8.23-1_i386.deb
sudo dpkg -i mc-data_4.8.23-1_all.deb
sudo dpkg -i mc_4.8.23-1_i386.deb

我们现在可以运行“mc”，但不能运行“apt full-upgrade”，因为此命令安装了较新的“mc-data”并删除了与其不兼容的“mc”。
