Recently I've upgraded Ubuntu to latest 17.10 Artful Aardvark. One of the evenings I've blindly executed
do-release-upgrade like I does year ago for v16.04. Surprisingly for me, the command was done successfully. It was late and after installation I've turned off power for notebook and go to sleep.
Next morning I turned on my notebook and trapped in a nightmare :). It seemed like Ubuntu hungs right before it is going to show GUI desktop. Last I've seen on the screen was mysterious boot log:
... [ OK ] Started CUPS Scheduler [ OK ] Started Trigger anacron every hour [ OK ] Listening on CUPS Scheduler Starting Console System Startup Logging... [ OK ] Started systemd-resolved-update-resolvconf.path [ OK ] Reached target Paths [ OK ] Listening on Avahi mDNS/DNS-SD Stack Activation Socket Starting Socket activation for snappy daemon [ OK ] Listening on D-Bus System Message Bus Socket Starting systemd-resolved-update-resolvconf.service....r...server...p link was shut down....
This last line with many dots... There was thoughts in my mind that I'll need to reinstall the system from the scratch. And I'll need to save all my data before reinstall. Arggghh :)
Hopefully, I rescued my Ubuntu installation. In this blog post I'll list possible solutions that I've tried and one that really helped.
