Please describe your issue:

I'm not exactly sure what happened but I can't update my chroot.
Here are the commands and output:

chronos@localhost ~ $ sudo crouton -un mojave
Downloading latest crouton installer...

chronos@localhost ~ $ sudo crouton -un mojave -r focal
focal does not belong to any supported distribution.

I installed bionic and then upgraded with update-manager-core's do-release-upgrade and it upgraded successfully. That's the only thing I can think of that might have caused this issue.

Added focal to the list of Ubuntu releases. It should work* now.

* for certain totally-untested definitions of "work"

If you run sudo crouton -r list you'll see 'focal' is not listed:

Recognized ubuntu releases:
    warty! hoary! breezy! dapper! edgy! feisty! gutsy! hardy! intrepid! jaunty!
    karmic! lucid! maverick! natty! oneiric! precise! quantal! raring! saucy!
    trusty! utopic! vivid! wily! xenial yakkety! zesty! artful! bionic* cosmic!
    disco* eoan*  

Releases marked with ! are upstream end-of-life, and should be avoided.
Releases marked with * are unsupported, but may work with some effort.

So specifying '-r focal' will not work since 'focal does not belong to any listed (supported or unsupported) release'.
You can still update & upgrade your chroot in the chroot but you can no longer update your version of crouton IIUC.

Hope this helps,
