Ubuntu has the problem of apt-get: Package has no installation candidate

When I installed vim today, the problem of Package 'vim' has no installation candidate appeared

 

The solution is as follows:
# apt-get update
# apt-get upgrade
# apt-get install <packagename>

This way you can use apt-get normally~
