The problem was that I adding debian repositories to my ubuntu, in order to install some packages from there. Those 2 files (libfile-fcntllock-perl and python3-netifaceswere) were accidentally updated from debian repos, but adding these repositories was a bad idea, so I ended up reinstalling ubuntu.
