Doing this as part of a dist-upgrade between releases does not make for a very usable experience, because the upgrade will be at an arbitrary point in the upgrade when the screen preinst script is run, which may cause apt to abort with the system in a state that a subsequent 'apt-get dist-upgrade' run is not sufficient to correctly upgrade from. > > it's incredibly bad form for the new upstream version to have broken > > protocol compatibility like this. > I agree. > > I think the screen maintainer should insist on upstream fixing > > protocol compatibility before allowing this version into unstable. > I'd be happy if you could write that on screen-devel.
