Hi Alexander,
on upgrade the server needs to restart and this fails:

>From the log:
invoke-rc.d: initscript mysql, action "start" failed.

There isn't much more to that in the log itself, the following might be 
$ systemctl status mysql

Never the less there is more to be found in your logs, I saw:
2018-02-01T18:18:40.003189Z 0 [Note] InnoDB: Initializing buffer pool, total

That appears to me as an issue in the config vs the system size.
Maybe also everything is allocated in other applications.
You could try shrinking the buffer and retry the upgrade:
innodb_buffer_pool_size = 1M

In that it seems to me like [1] or actually bug 1312936

Could you look into the memory (and concurrent session config) if they
could be reduced for the upgrade. You can afterwards still look if/what
consumes your memory, resolve it and increase again.

P.S. There also is this
[ 1134.054457] type=1400 audit(1517509116.605:24): apparmor="DENIED" 
operation="open" parent=14364 profile="/usr/sbin/mysqld" 
name="/sys/devices/system/node/" pid=14365 comm="mysqld" requested_mask="r" 
denied_mask="r" fsuid=0 ouid=0
But I think it is unrelated (only needed for mysql configuring Numa behavior 
and fixed in later Ubuntu releases afaik)
