Unable to access Files

[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.

@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

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.

[robi]

After the 3rd time of my client rebooting the server this week, I decided to try my hunch.

Looks like I was right @girish ; this fixes the issue.

@import '/app/code/core/css/whatsnew.scss';

Please do the needful

[girish]

@robi Looks like non-cloudron users hit the same issue - https://github.com/nextcloud/server/issues/13556#issuecomment-848314122
