Hi –
I’m unable to get Nextcloud up and running following an upgrade from Ubuntu 18.04 to Ubuntu 20.04. Please note that everything worked as of a couple of hours ago, and had been flawlessly for months. A quick overview of the events leading up to my current issue:
- Upgrade Ubuntu 18.04 to 20.04. However, in this process, PHP, too, gets updated to version 7.4.xx, leading to:
This version of Nextcloud is not compatible with > PHP 7.3. - Not immediately able to fix this, I purge my system of
php7.4*(as well asphp7.3*,php8.*to catch anything lingering from my attempts of solving the above by downgrading PHP), and installphp-7.3from scratch.
Running php -v now shows PHP 7.3.28-2+ubuntu20.04.1+dev.sury.org+1, yet Nextcloud remains inaccessible.
- Unsure what to do, I ran
sudo snap refresh nextcloud --channel=17. This installed and upgraded Nextcloud to revision 23903. Nextcloud remains inaccessible, but checkingsudo systemctl | grep nextcloudshows:

I assume this explains why I cannot access anything. However, checking sudo systemctl status snap.nextcloud.apache.service merely yields:

Not entirely sure what is going on, I attempted to further refresh Nextcloud seeing how versions 18, 19, and 20 should all be available. However, running
sudo snap refresh nextcloudtells me that Nextcloud is up-to-date. -
I attempt to run
php /var/www/nextcloud/index.php, but encounterPHP Fatal error: Uncaught Doctrine\\DBAL\\DBALException: Failed to connect to the database… realising that my purge in step 2 might have deleted MySQL, I installsudo apt install php7.3-mysqlsuccessfully. -
I can now run
php /var/www/nextcloud/index.phpwithout any errors, but I am still unabe to access my192.168.x.y/nextcloudinstance. At this time, I’ve already restarted the machine several times, but do so once more. The issue persists. -
Not convinced upgrading Nextcloud is really the way to go right now, I seek to restore my system to the state it was prior to upgrading to 20.04. I did this by running
sudo snap revert nextcloud, allowing me to go back to revision 18204 with version16.0.7snap2.
Attempting to access 192.168.x.y gives me the Apache2 screen.
Attempting to access 192.168.x.y/nextcloud gives me a blank screen, i.e. an internal server error.
- This suggests that a secondary Apache installation is running. I run
sudo systemctl stop apache2followed by asudo snap restart nextcloud.
Attempting to access 192.168.x.y gives me the Apache2 screen.
Attempting to access 192.168.x.y/nextcloud yields a 404.

Seeing how the snap.nextcloud.apache.service is running now, it might have been a conflict with the other service, which no longer shows as currently running. Interestingly, attempting to access localhost yields the following:
… so something is running, just not the instance I previously had running.
Running sudo nextcloud.occ shows the following:

It seems like I have somehow managed to stat the installation of Nextcloud instead of just returning to the one I was previously using. I have not edited anything in the config.php file, and have a copy of this elsewhere.
Any help moving forward would be greatly appreciated. This all worked prior to upgrading to Ubuntu 20.04. I suspect that the upgraded PHP, which caused the initial issue, and my handling of that, is the root cause.
Thanks!
