Some packages could not be installed. This may mean that you have

The following information may help resolve the situation:
The following packages have unmet dependencies:
python : PreDepends: python-minimal (= 2.7.15~rc1-1) but it is not going to be installed
Depends: python2.7 (>= 2.7.15~rc1-1~) but it is not going to be installed

Looks like you are trying to install the package from some non-Ubuntu source, or you tried (and perhaps failed) to install and didn't clean up afterward. Useapt-cache policy libpython2.7-minimalto determine which non-Ubuntu or obsolete source the 2.7.15~rc1-1ubuntu0.1 version is coming from, then disable that source, then runsudo apt updateto refresh your package database from the remaining (valid) sources.
