[Bug 2002945] Re: dist-upgrade failed in many unpredictabl ways

[Davide Prati]

Many thanks for your detailed reply Nick, this is really helpful. I have looked in my firefox history and I have found the name of the package (I was searching on google on my laptop while trying to fix my desktop).The package that was causing dependency problem in the first place was libdvd-pkg. I have removed it and then i was able to launch dist-upgrade.
Regarding the network error, simple tools like net-tools were not installed(but I am 100% sure they were there before the upgrading process). Unfortunately I am not able to collect more details about it.
The apparmor error was "Failed to start apparmor", I have found it in my firefox history. I do not remember the correct path of the mysql profile, I can not be 100% sure that it was /etc/apparmor.d/abstractions/mysql but after I have removed the mysql profile I was able to get apparmor working. Probably this is a duplicate of https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1861250 ?

Regarding the nfts partition, the message log that I have seen was
"e2fsck: Cannot continue, aborting"

Also, I had also this

the upgrade process.

Title:
  dist-upgrade failed in many unpredictabl ways

Status in ubuntu-release-upgrader package in Ubuntu:
  Invalid

Bug description:
  I haven't find a better place to report my experience, without any doubts the worst dist-upgrade since 8 years. I have finally fixed everything but it was a real pain. I will describe here what went wrong, in the hope that the next dist-upgrade will be better.
  - I have launched the upgrade from command line apt dist-upgrade as the GUI tool was not doing nothing, not event reporting a message. There was a packet holding back, I have uninstalled it with synaptic and then apt dist-upgrade started

  - The boot failed. I have looked in the log and an apparmor profile was blocking the boot, because one file could not be parsed. The error was in the mysql file that can not be parsed. I have moved this in another folder and this error message was gone.
  - Still the boot did not start. I was thinking that maybe some package is misconfigured, I have run apt update but there was no internet connection, and ifconfig was telling me that net-tools were not installed. I have entered rescue mode, I have re-anabled the networking, then check the dependency, and then the boot started.
  - But still, the computer was booting just in rescue mode. I have looked into the logs (because the journalctl command was not reporting any failure) and I have seen that a partition could not be found. It was an nfts partition that I have created to share data between ubuntu and windows (I have a dual boot installation). I have commented out that line in /etc/fstab and it worked. But stil I did not understand why it can not be read anymore. ntfs-3g and fuse are installed, it should work as before.

  Anyway, to recap:
  1) graphical upgrade tool was not able to report which package was holding back the upgrade process
  2)the mysql file in snap can not be parsed and that blocked the boot, measure a bit too excessive IMHO
  3)network was unreacheable because some basic programs were uninstalled
  4)NFTS partition was unreadable and the journalctl command, was not reporting the name of the failed partition

  Now everything works again and looks good, except the nfts partition.
  I do not think this is the right place were to report my upgrade
  experience, but I think it might be helpful to improve our beloved
  Ubuntu.
