Unable to download updates: The following packages have unmet dependencies

Ubuntu 21.04 64 bits

The warning window doesn't show what software has the problem.

I typed sudo apt-get update showing this:

Reading package lists... Done

Solution 1:

Run the following commands to update the packages manually:

sudo apt update
sudo apt dist-upgrade

The first command only updates your package list to let the system know what packages need to be updated. The second command actually performs the upgrade (software updates).

Alternatively, you could also run the following commands to achieve the exact same result:

sudo apt update
sudo apt full-upgrade

On a related note, you can skip kernel updates by running the following commands instead (not recommended):

sudo apt update
sudo apt upgrade

If it still shows the same message in the software center, run the following command to update vim manually:

sudo apt update
sudo apt install --reinstall vim
