[Bug 1826404] Re: do-release-upgrade tells me upgrades are only available from latest supported release when on latest supported release

[Balint Reczey]

Now I can't upgrade to Impish from Hirsute:

rbalint at chaos:~$ sudo do-release-upgrade -d
[sudo] password for rbalint: 
Checking for a new Ubuntu release
Upgrades to the development release are only 
available from the latest supported release.
rbalint at chaos:~$ cat /etc/issue
Ubuntu 21.04 \n \l
