Hello
Unable to upgrade Ubuntu 18.04 LTS to 20.04 LTS
Every now and then a window appears with a new version available. After clicking install now, the box disappears and nothing happens. Updates on 18.04 LTS on a regular basis. What could be the reason.
Thank you.
Unfortunately, the update was unsuccessful.
It was loading a lot of things and finally showing: an error occurred while updating -> restore the system to its original state.
Hello.
I tried again today to upgrade from 18.04.6 LTS to a higher version. First, I updated the current system. Then in the terminal I typed "sudo do-release-upgrade". While downloading the data, it displayed the message: no public key. The update failed. Is there any advice?
Ubuntu supports the ability to upgrade from one LTS to the next LTS in sequential order. For example, a user on Ubuntu 16.04 LTS can upgrade to Ubuntu 18.04 LTS, but cannot jump directly to Ubuntu 20.04 LTS. To do this, the user would need to upgrade twice: once to Ubuntu 18.04 LTS, and then upgrade again to Ubuntu 20.04 LTS.
But I don't see much point in doing this. As calvinmeadows pointed out above in #5, to get at the current 22.04 LTS you'll have to upgrade twice. Doing a backup of your data following by a fresh install of 22.04 would result in less hassle and effort.

Reason: typo
Distribution: Ubuntu based stuff for the most part

Your system does not have a connection to the Snap Store. for the
best upgrade experience make sure that your system can connect to
api.snapcraft.io.
Do you still want to continue with the upgrade?
I think that is the issue since Ubuntu uses Snap so heavily.
