Unable to access Files

[JOduMonT]

Neither any user (even Admin) was unable to access their Files via the WebInterface and no Files was showing up in the Dashboard. I'm speaking in past tense because I fixed it, so I just posting here in case someone else have the same situation.

the config

Nextcloud: Package v4.8.8-1 / App v20.0.8

• Nextcloud have is own dedicated drive + few external path, mainly from BackBlaze mounted in Nextcloud

the issue

• When you log in nextcloud web interface, every apps was working fine except File
  This directory is unavailable, please check the logs or contact the administrator

What I tried

0. Looking through the logs
1. reboot the apps
2. validate the space drive both / and /mnt/nextcloud
3. validate the owner:group of /mnt/nextcloud/$users/files/
   everything was/is fine
   I even restore the apps under another name and the issue was still remaining.

so What did you do Doc ??

the solution

1. I create a new user directly via nextcloud (not in cloudron) and login with it and everyone gain access to their file.

Mysterious, yes I would say.

does someones have an explanation and/or had the same behavior in the past?

[robi]

We just hit this issue and tried all the same things to no avail.

Will create a new user to see if that helps kick things back into working order.

Thanks @JOduMonT

[robi]

Created new test user, added to test group, logged in, restarted NC from CL - same problem.
Btw, we're using a different version than above:

Nextcloud 21.0.1
com.nextcloud.cloudronapp@4.9.0

What plugins do you have installed? Have you tried disabling all/most of them?

[robi]

@girish just defaults.

This link has a few suggested solutions: https://help.nextcloud.com/t/users-cannot-acces-their-home-folder-after-upgrade-to-14-0-1-this-directory-is-unavailable-please-check-the-logs-or-contact-the-administrator/38200/3

Turn off File Sharing is one. Another is to run occ files:scan -all in the Terminal But this is from 2018, and for version 14. I reckon it won't hurt to try some of the solutions there.

[robi]

@scooke the occ command now only has a --all (notice the extra -.

scan didn't change the internal server error.

[robi]

There was a message to run the ocs command as the webserver user www-data.

Trying that in terminal as root gives:

su www-data
This account is currently not available.

Yet all user files exist under that www-data user.

[nebulon]

@robi in Cloudron to rescan files, use the command mentioned at https://docs.cloudron.io/apps/nextcloud/#rescan-files

[robi]

@nebulon Thanks, but it made no difference. Scan results are the same.
All files are there, the Files app simply errors, and I don't see where it logs the error.
Doesn't appear to be in /app/data

[girish]

Just looking into @robi 's server now. First, I enabled debug in /app/data/config/config.php by setting debug to true and loglevel to 0.

I got this trace:

Looks like whatsnew.scss is missing . I checked a couple of other nextcloud installs and that file isn't there either. This led me to this https://bbs.archlinux.org/viewtopic.php?id=263820&p=5 about several other broken nextclouds...

@robi said in Unable to access Files:

@girish just defaults.

There seems to be quite of a few of them installed. Atleast, 15 more than the standard one.

[girish]

@robi I have temporarily fixed the problem by commenting out a line in /app/code/apps/files/css/merged.css . I think we will have to ask the upstream nextcloud to ask what the issue is. I suspect the issue is from some plugin you have to disable them one by one to know what is causing the problem.

[girish]

So strange, all the installs look the same and yet yours errors. I can't figure what it is, I have to try again with fresh pair of eyes later.

[robi]

@girish Thank you a whole bunch.

It does look like someone had fun installing some NC Apps, and after I found where those were, a few needed updates.. most are featured and come with NC, and the others look disabled as they are untested, so they have the button to enable them. I left them that way.

One had an error upgrading so I removed it.

[robi]

Internal Server Error came back, so went to disable all plugins and it didn't help.

After trying all the lines in the merged.css file this one seems to be the culprit which was uncommented as below.

/* @import '../../../core/css/whatsnew.scss'; */

[robi]

@girish perhaps that relative path is part of the problem, and needs to be absolute?

[girish]

@robi right, I don't quite understand why it works fine in a default install with relative paths though (it's relative in all the nextclouds I have access to as well). So, there is something different in your install, not sure what.

[robi]

@girish you're welcome to login again, i'll keep the access credentials the same until resolved.

it'll happen again when the server restarts ;-/

[girish]

@robi OK, thanks, will get to it at some point this week.
