The Basics
- Nextcloud Server version: 30.0.8 (maybe - see below)
- Operating system and version: Ubuntu 22.04.5 LTS
- Web server and version: Apache - not sure which version, managed by snap
- Reverse proxy and version: Apache (I guess? Not sure how to check)
- PHP version: 8.2.26
- Is this the first time you’ve seen this error? (Yes / No): Yes
- When did this problem seem to first start?: This morning
- Installation method: snap
- Are you using Cloudflare, mod_security, or similar? (Yes / No): I don’t think so. Everything is local
Summary of the issue you are facing:
Basic symptom - Nextcloud is unreachable through browser.
More detailed symptoms - please note that I’m a beginner Linux admin. I know enough CLI to read logs and run commands - so ELIF is much appreciated. I keep a running text file of what I’m doing, if you need any additional details, I can provide them. Pastebin rejected my dump of my logs from the troubleshooting I’ve done. Something about a smartfilter… :?
-
System was extremely sluggish to ssh into and I could not do a “sudo reboot now” so I had to hard power cycle the box.
-
When it came up, Nextcloud was still unreachable.
-
Reviewing /var/log/syslog told me that at some point, during routine shutdown/startup of nextcloud snap, systemd core dumped.
-
Doing a “sudo snap list --all” shows me that I have two nextclouds on my box:
||nextcloud 30.0.8snap1 46970 latest/stable nextcloud✓ disabled|
|---|---|
||nextcloud 31.0.2snap1 47222 latest/stable nextcloud✓ -|
-
Doing a “sudo snap start nextcloud” reports “Started.”
-
Looking at “sudo snap info nextcloud” says that it’s still disabled?

“ps -aux” says that various nextcloud bits are running, so I try to access my server via https. No luck
-
On a guess, I tried to access nextcloud via http and I see the following error on the browser:
App directory "/snap/nextcloud/current/htdocs/apps" not found! Please put the Nextcloud apps folder in the Nextcloud folder. You can also configure the location in the config.php file.
- I looked at /var/snap/nextcloud and this is what I see:
46970 47222 common
At this point, I’m stumped. Is it a failed upgrade? When systemd coredumped, did something get left undone and I’m in this weird middle state?
Most importantly, how do I recover?
Fortunately, my data is still there, I checked those directories - and I’m synced on my local workstation. The only downside is loss of my primary calendar at the moment, but I have it on my mobile device, so there’s that for the moment.
Help?
