SOLVED Revert Cloudron version?

[stoccafisso]

Hi

I try to restore a backed up cloudron (upgraded server OS), but setup the wrong cloudron version on my new server. Need to revert to older cloudron version that corresponds with the backup version.

Is there a way to force cloudron to revert to an earlier version, or do I simply need to uninstall the cloudron and install the correct version?

What is the best way to do it? Is there a working command for "uninstall cloudron", or do I have to reinstall the whole server OS and start over again?

Thanks

Hmm.....

I actually reinstalled the server OS (Ubuntu 20.04) and started all over from scratch.

./cloudron-setup --provider generic --version 5.5.0

Then installation stopped and gave error msg. From /var/log/cloudron-setup.log:

Package mysql-server-5.7 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  mariadb-server-10.3

E: Package 'mysql-server-5.7' has no installation candidate

So, as the cloudron I try to reinstall is a subscription cloudron (paid), but with no critical information stored on it, would it be easier to just install a fresh latest version cloudron, and have you guys (support) change the running subscription so it is connected to this new cloudron ID?

@stoccafisso looks like the Cloudron version you are trying to install did not support Ubuntu 20.04 yet. Please try the same with a server running Ubuntu 18.04.

@nebulon

Thank you. I tried using 18.04, installation went well, but when I picked the restore option, filled in the details for downloading my my DO Spaces backup, I tried once and forgot archive encryption key, then filled in the key, but now got error message:

"Already activated. Restore with a fresh Cloudron installation."

Maybe its easier to install a fresh cloudron, and have you guys connect it to the running subscription?

Please advice how to proceed.

Hold on a minute....seems like restore worked well after all....strange thing....I check it out and report back....

I had to install 18.04, then install Cloudron 5.5.0, then restore the backed up cloudron, then upgrade it to 6.1.2, then make a backup.
Then destroy the 18.04 and install 20.04 instead, then restore the 6.1.2 backup....puhh. Done, working!

(Could not restore a 26GB Nextcload app, but no problem, had the files backed up locally)

Guess this thread can be marked as solved?
