(3) I expected the upgrade to 20.04 from 18.04 to happen without any issues.
(4) The upgrade failed with this error message. I have also attached the contents of /var/log/
An unresolvable problem occurred while calculating the upgrade.
This was likely caused by:
* Unofficial software packages not provided by Ubuntu
Please use the tool 'ppa-purge' from the ppa-purge
package to remove software from a Launchpad PPA and
try the upgrade again.
If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-

Thank you for taking the time to report this bug and helping to make Ubuntu better.
I see a number of 3rd party packages, esp. from https:/ /launchpad. net/~oibaf/ +ppa-packages
For best results with a release-upgrade, you should remove all 3rd party packages (bringing your system back to a pure Ubuntu one, ie. no 3rd party packages) then perform the upgrade. The tool ppa-purge can assist with this.
Likely related to https:/ /bugs.launchpad .net/ubuntu/ +source/ ubuntu- release- upgrader/ +bug/1069133
(following from https:/ /bugs.launchpad .net/ubuntu/ +source/ ubuntu- release- upgrader/ +bug/1922546/ comments/ 2)
[The use of oibaf ppa] 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 ppa:oibaf/ graphics- drivers' . After that you can try upgrading again and if it still fails open a new bug report. Thanks and good luck!
