Disk error during live install

[Roman Kolodziejczyk]

After following steps to install from the 'Install (Live session) - (Legacy)...' Testcase on iso.qa.ubuntu.com I ran into an error with the disk after the password is set.

Files were being copied for install and the <Welcome to Ubuntu> slide was up. I haven't had issues with installing from this media before.

There was a GTK error early on but everything worked properly after that.

From UbiquitySyslog.txt:

It's possible you had a bad write to your installation media or for some other reason its contents could not be read correctly at this time. If you're still having problems you should try re-writing the image to your media (and may be re-download the image as well).

Ubuntu Lunar (23.04) was released some time ago and with no comments after #2 I'm closing this by changing the status to 'Invalid'. It seems to be an issue at user level and not with the ISO image itself.
