Mirror source settings
Ubuntu has different system versions, and for different versions, the mirror sources that need to be set are slightly different.
Use the following command to check your Ubuntu system version:
lsb_release -a # Display related information lsb_release -c # Only display version information

Update source
After setting up the mirror source, use the following command to update:
sudo apt-get update sudo apt-get upgrade
Question
When using Linux, I encountered a problem that has been solved. The problem is as follows:
The following packages have unmet dependencies: aptitude : Depends on: libapt-pkg5.0 (>= 1.1) but it will not be installed Recommended: libparse-debianchangelog-perl but it will not be installed
The root cause of the above problem may be that the image source setting is incorrect, that is to say, the image source set does not match the Ubuntu system version; setting an image source that matches the system version can solve the problem.
