Build in upgrade from 2.2.47 to 2.2.48 (or 2.2.48.1) fails with cannot create regular file (release-upgrades)

Sorry, I currently don't have time to do a broader deep dive on this myself, maybe this helps as a starting point in case others experience this too.

I tried upgrading from 2.2.47 to 2.2.48.1 with the build in upgrade tool (initial install was via 2.2.47 KVM disks) downloaded here https://github.com/GNS3/gns3-gui/releases/tag/v2.2.47

Error message is

cp: cannot create regular file '/etc/update-manager/release-upgrades': No such file or directory

system was rebooted in between tries, system time is correct

I'm having the same exact issue. Current version 2.2.47, and trying to upgrade to 2.2.48 or 2.2.48.1 fails with the same message.

Just did

cd /etc sudo mkdir update-manager sudo gns3restore

and VM is upgraded to 2.2.48.1

Thanks for the report. I have fixed the upgrade script and upgrades should work now.
