Thank you for your report.

Ubuntu 18.04 LTS is intended to upgrade to Ubuntu 18.10 (https://wiki.ubuntu.com/CosmicCuttlefish/ReleaseNotes) or to Ubuntu 20.04 LTS (after 20.04.1's release), ie. the next release or next LTS release.

If you read Ubuntu 19.04's release notes (https://wiki.ubuntu.com/DiscoDingo/ReleaseNotes) you'll note only mention of upgrading from Ubuntu 18.10 as this is all that's supported.

For information on Ubuntu upgrade paths please see https://help.ubuntu.com/community/UpgradeNotes

Bug reports on an untested and unsupported upgrade path make little sense, thus I've marked this bug report invalid. If you believe I'm in error, please change it back to new and give a reason why you believe it's valid. Thanks again for using Ubuntu.

Now that 18.10 is EOL, the upgrade path from 18.04 now points to 19.04. I've just checked on my own 18.04 installation and I've been offered an upgrade with the following text displayed:

"The software on this computer is up-to-date."
"However, Ubuntu 19.04 is now available (you have 18.04)."

I think the upgrade failed due to the following extracted from the logs:

2019-07-26 16:07:32,915 DEBUG Installing 'xserver-xorg-video-all' (Distro KeepInstalledPkgs rule)
2019-07-26 16:07:33,183 ERROR Dist-upgrade failed: 'E:Unable to correct problems, you have held broken packages.'

Reverting status to "New".

Any update on how I can find a list of said 'held broken packages' and/or a solution to fix them in order to actually upgrade ubuntu?

Solutions I have tried include all of these :
1) https://askubuntu.com/questions/223237/unable-to-correct-problems-you-have-held-broken-packages
2) https://appuals.com/fix-unable-correct-problems-held-broken-packages/

Didn't help me, those links..

Any help or advice would be much appreciated

Reviewing the files from your upgrade attempt you seem to have enabled a PPA that provides Xorg packages. This will prevent the upgrade as that PPA contains package version numbers greater than the release to which you are upgrading. You can revert the PPA by installing the ppa-purge package from the official Ubuntu archive and then running 'sudo ppa-purge oibaf'. After that you try upgrading and again and if it still fails open a new bug report. Thanks and good luck!
