do-release-upgrade requires the current system have up-to-date patching in
order to work. I have a client with a number of Ubuntu 16.04 systems, how long
will those packages be available? If they are going to become unavailable
before all Ubuntu 16.04 servers are upgraded, can I download the needed debs
and put them on an apt-cacher server (and point to it for updates) until
everything is upgraded?
Second question due to my fault, I pressed enter when prompted by molly-guard
for the server name at the very end of a do-release-upgrade moving from Ubuntu
16.04 to Ubuntu 18.04 and got in a weird state. I did a manual reboot and
sources.list didn't get updated - still refers to xenial. I discovered this
when Postgresql 10 wasn't available. The kernel is Ubuntu 18 and a check of
package versions shows they are Ubuntu 18.04, can I simply get a copy of
sources from an Ubuntu 18.04 system and use it? What else didn't get done due
to an improper reboot? Is there something I can read to determine this and
make the necessary changes manually?
Thanks for your help.
