HELP! Upgrading 22.04 to 24.04 - root disk space runout...

[Bo Berglund]

What can I do now?
This is an HP workstation laptop that has been running Ubuntu 22.04.4 LTS with
the Mate desktop and today I got a message about upgrading to 24.04 LTS.

So I am doing a relese upgrade from 22.04 to 24.04 from the desktop and in the
middle of the process it pops up a message about the root space running out...

That partition is 30 GB and I have plenty of space elsewhere including
non-partitioned space of some 500 GB...

The initial inspection in the upgrade process did not say anything about the
disk space, but now it seems to have run out....

Does this mean that my laptop is hosed?

Right now the process stopped for user entry asking "Replace the customized conf
file etc/sudoers".

So the upgrade is on pause....


At this point I will not click any button if that means the computer is dead
when it works its way through all changes and has no disk space....

I would have expected the system to analyze available space on disk *before*
starting the actual process and if low on disk space suggested some remedy
before actually departing on the one-way street of the upgrade....

So this laptop has two big drives and the main disk has a lot of unpartitioned
space.
Home is on a separate partition and there is lots of space available there, but
I assume that the Ubuntu system will be on a single partition for / and that is
the one partition too small....

How can I rescue this?

I believe it is not possible to just cancel the upgrade, come back to the system
and enlarge the root partition, right?
In fact a partition in use cannot even be modified, I believe?

Not so good New Year....
