apport information ** Tags added: apport-collected xenial
** Description changed: Last week I upgraded from 12.04 LTS to 14.04 LTS and then immediately to 16.04 LTS. 12.04 was not entirely stable; something was crashing regularly, and the Ubuntu tools make it hard for a user to determine what. The upgrade went moderately well; I now get error messages during system startup (about an unnamed file not being found) and a couple of other bits of flakiness, but I counted it as a success and the system as functional. This morning I tried to wake up my screen, and nothing much happened. I then attempted to ssh to the ubuntu box from another system. This requested my password almost instantly, as normal - but then nothing else happened, and the connection eventually dropped. I conclude that IP and TCP are functional, and it's possible for some processes to respond, but not many. So it's not a complete kernel hang. (In particular, I'm seeing evidence that it's getting beyond things done at interrupt level.) I don't have any debugging aids installed, so I don't believe I can get a kernel crash dump, which is what I'd want if I were debugging this. I *can* potentially retrieve and attach logs, but you'll have to tell me which ones are relevant, and do so before they rollover. (Also, logging will have to be functioning; IIRC, there were syslog issues in 12.04, and while I'd implemented whatever fix was reccommended at the time, I haven't looked at my logs since the upgrade.) This is a desk top system originally from System 76 - i.e. built for linux - that's also running a bunch of server software (postfix, apache, ...) I was not (knowingly) running anythign unusual at the time - probably Unity, a few shells, firefox, maybe guncash and/or emacs - and all the usual demons. IIRC, I was not at the very latest versions of all software installed - some new versions ahd come out since I upgraded, and I was going to deal with installing them on the weekend. - I'm going to hard reboot the system now. I can then gather identifying - info. If I have time this AM before work, I'll check for standard things - you want in all bugs, and add them. (Right now I'm posting from my Mac - laptop ;-)) + I'm going to hard reboot the system now. I can then gather identifying info.
