does the system boot to a working system afterwards?
dirty / fingerprints on disk?
to remove the possibility of medium issues and reader issues, if you have the downloaded .iso on your HDD, you can boot to it and start your upgrade from there.
the .isos do have a modified net-install to start them, so if you interrupt the DVD disk installer boot-up when it is looking for USB devices (just eject the disk) you can point the installer to the .iso you have stored on your HDD. should be ok as you are not formatting / or /home.
next time you attempt the upgrade, have handy a small USB stick.
when the installation error occurs, insert the usb stick, wait a few seconds and then "Ctrl+Alt+ F2" should bring up a tty.

- Code: Select all
bug
and you will be asked where to write the file to /sdb, /sdc etc (your usb stick).
then file a bug report and attach the contents of the bug report.
you may need to compress it first with xz
file usually ends up with a name like: report.bug.xz
