I had the same problem, but my log started like this: Log time: 2020-10-21 09:38:03.264979 MarkInstall python-is-python2:amd64 < none -> 2.7.17-4 @un uN Ib > FU=1 Installing python2 as Depends of python-is-python2 MarkInstall python2:amd64 < none -> 2.7.17-2ubuntu4 @un uN Ib > FU=0 Installing python2-minimal as PreDepends of python2 MarkInstall python2-minimal:amd64 < none -> 2.7.17-2ubuntu4 @un uN Ib > FU=0 Removing: python-minimal MarkDelete python-minimal:amd64 < 2.7.15~rc1-1 @ii mK > FU=0 Installing libpython2-stdlib as Depends of python2 MarkInstall libpython2-stdlib:amd64 < none -> 2.7.17-2ubuntu4 @un uN Ib > FU=0 Removing: libpython-stdlib MarkDelete libpython-stdlib:amd64 < 2.7.15~rc1-1 @ii mK > FU=0 Removing: python MarkDelete python:amd64 < 2.7.15~rc1-1 @ii mK Ib > FU=0 Starting pkgProblemResolver with broken count: 1 Starting 2 pkgProblemResolver with broken count: 1 Investigating (0) python-support:amd64 < 1.0.15 @ii mK Ib > >>> Broken python-support <<<:amd64 Depends on python-minimal:amd64 < >>> 2.7.15~rc1-1 @ii gR >
I've purged python-support, and solved the problem (i.e. it's installing now). It had only 6 packages depending on it. >From your log "nodejs" might be the problem, maybe a leftover from some ppa. >Proceed with caution when removing python packages.
