The dialog which follows is the final question before the upgrade actually begins. If you choose N here your system will be restored to its previous state. Calculating the changes Do you want to start the upgrade? 3 installed packages are no longer supported by Canonical. You can still get support from the community. 16 packages are going to be removed. 322 new packages are going to be installed. 1391 packages are going to be upgraded. You have to download a total of 1,156 M. This download will take about 2 minutes with your connection. Installing the upgrade can take several hours. Once the download has finished, the process cannot be canceled.

Are you talking about this question (see copy of the output in the terminal below)? Reading cache Checking package manager Continue running under SSH? This session appears to be running under ssh. It is not recommended to perform a upgrade over ssh currently because in case of failure it is harder to recover. If you continue, an additional ssh daemon will be started at port '1022'. Do you want to continue? Continue [yN] At this time I press N to stop. However, this comes very early in my experience and the result is the same with and without the -p option. Last time I tried to upgrade the machine directly I also remember more stuff coming out in the terminal before the error occured. Or is there another point later at which you can choose to upgrade or abort? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1924951 Title: Cannot upgrade from 18.04 to 20.04 "An unresolvable problem occured while calculating the upgrade."

[Bug 1924951] Re: Cannot upgrade from 18.04 to 20.04 "An unresolvable problem occured while calculating the upgrade."
The error that you encountered was with calculating the upgrade, which only changes your /etc/apt/sources.list file from your old release to the new one and then calculates the upgrade. To test the fix it would be enough to just run the upgrade process to the point where it asks you if you want to upgrade and then quit the process. That being said I've enough positive feedback so far to feel confident that the change works so do whatever you feel comfortable with. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1924951 Title: Cannot upgrade from 18.04 to 20.04 "An unresolvable problem occured while calculating the upgrade."

Thanks for the help Brian, really appreciated. This is just to inform you that it will take a while until I can try this and report the results back to you. This machine is located at my workplace, but due to the recent increase of Covid-19 cases in Singapore we are supposed to work from home for now. As doing a release upgrade is discouraged via ssh, this will have to wait a few weeks until we can go back to the office.

Thanks for taking the time to report this upgrade failure. There is currently a new version of the release upgrader available in -proposed which may resolve the error you've encountered. Please run the following command to test the new version of the upgrader: do-release-upgrade -p Please lets us know the results in this bug report.
