I only now noticed that you also opened bug 1988409 previously. While
you may have disabled the problematic PPA, you still have packages
installed from it (see my previous comment). You need to purge
libfreerdp2-2 which was installed from this PPA, and then install a
version from the official Ubuntu archive.
