You could try downgrading the two library packages explicitly: $ apt-get install libtiff5=1.0.10-4 libidn2-0=2.0.5-1 That might result in other errors if doing this breaks versioned dependencies from other packages, but it's at least a starting point, and worth trying. The real questions are A: how you wound up with these newer versions installed in the first place, and B: whether there are similarly "newer than anything available in your-configured repos" versions of any *other* packages installed. Tracking those down and fixing them would definitely be possible, but honestly, if this system was installed so recently you're probably better off doing the reinstall and hoping whatever error it was doesn't happen this time. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
