There was no sign of corruption. Once the original gdm3 also failed and given that the config in etc was the original, the only thing left to check was the var/lib that I saw referenced in the Xorg cmdline.
I was able to upgrade gdm3 without problems. The SSD did not run out of disk space it has several tens of Gb free. I will check the SMART stats later but I doubt it had any.
