How could I downgrade to 7.3?
Upgrading ubuntu when you have a lot of thing on your server is silly.
Ubuntu have always the last software, then your service won’t like the last php7.4 because they rely on old versions

I don’t use 20.04 and I doubt very many people here do. Try finding the .deb packages and manually install them.

what is a .deb package?
Reinstall on 18.04 or debian 10 or upgrade to v18.
Other then that you need to hire someone to do this for you.

Nate can still upgrade. He just has to go through a manual upgrade and it doesn’t sound like he can do that task.
Rock and hard place. Don’t upgrade your OS again without testing first.

Ok i have leaned my lessen on not upgrading my os.
Hello
Bad idea, you should upgrade your OS but you have to inquire before. Nextcloud is not a apt package on debian or Ubuntu, as a consequence, there may be compatibility issues. In the official NextCloud doc, (https://docs.nextcloud.com/server/18/admin_manual/installation/system_requirements.html ), Ubuntu 20.04 is not recommended. Maybe because the doc is not up to date, we cannot know. So lets the NextCloud Team updating the doc to be sure that the last version of whatever is compatible.
