NCP: Internal Server Error following upgrade

ā„¹ļø Support šŸ“¦ Appliances (Docker, Snappy, VM, NCP, AIO)
1

On Saturday I upgraded ncp and nextcloud.
Everything seemed to go OK, but today when I try to access Nextcloud from the web interface I get

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

Iā€™m also unable to access my files and synced calenderā€™s from mobile and desktop clientā€™s.

I can access ncp via the web interface, I tried rolling back to the backup I made before the upgrade, but I still have the same problem.

I found a post in the forum that suggested I try
sudo -u www-data php /var/www/nextcloud/occ maintenance:repair

But that has not fixed the issue, does anyone have any suggestions as to what else I can try?

The only log I could find was /var/log/ncp.log which ended with

I tried the command listed in the warning

systemctl daemon-reload

but this did not seem to do anything.

Any help would be appreciated.

I should also have mentioned Iā€™m running on a Raspberry Pi 3

I after more searching I found a post which suggested I change

'memcache.local' => '\\OC\\Memcache\\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',

to

'memcache.local' => '\OC\Memcache\Redis',
'memcache.locking' => '\OC\Memcache\Redis',

But this did not fix the issue, and another post on the Raspberry Pi Forums which suggested this should be

'memcache.local' => '\OC\Memcache\APCu',

which I seem to recognize from an earlier NextCloud install, but that still did not fix my issue.

ā€˜memcache.localā€™ => ā€˜\\OC\\Memcache\\Redisā€™,
ā€˜memcache.lockingā€™ => ā€˜\\OC\\Memcache\\Redisā€™,

Is the setting on my RPi2B+ running
NCP v1.35.0
NC 20.0.8.1
NextCloudPi image NextCloudPi_03-09-19
Raspbian GNU/Linux 10

Cheers @OliverV,

That is what my setting used to be, so I have reverted to that, but I still have the same issue.

My system config (after rolling back the update to 20.0.8 which seem to have caused this) is
Pi3
NCP v1.35.0
NC 20.0.2.2
NextCloudPi image NextCloudPi_03-09-19
distribution Raspbian GNU/Linux 9
datadir /media/USBdrive/ncdata
data filesystem ext2/ext3
swapfile /var/swap
dbdir /media/USBdrive/ncdatabase
Nextcloud check ok

I notice you are Buster while I am still on Stretch, could that be the issue?

I did not notice the dist_upgrade until I sshā€™ed in following my problem, and did not want to run that update in case it made my problem worse.

I can still get to the ncp web interface, just not nc.

Very likely, Iā€™d make backups if needed, and upgrade to Buster.

I tried running the upgrade, and had some errors

Iā€™ve listed the full output below, but it looks like the main error is

The following packages have unmet dependencies:
 php7.3-bz2 : Depends: php7.3-common (= 7.3.27-1~deb10u1) but 7.3.27-9+0~20210227.82+debian9~1.gbpa4a3d6 is to be installed

Does anyone know how I can fix this?

Full outputā€¦

NextCloudPi v1.35.0 is up to date
Update to buster available. Type 'sudo ncp-dist-upgrade' to upgrade

>>> ATTENTION <<<
This is a dangerous process that is only guaranteed to work properly if you
have not made manual changes in the system. Backup the SD card first and
proceed at your own risk.

Note that this is not a requirement for NCP to continue working properly.
The current distribution will keep receiving updates for some time.

Do you want to continue? [y/N]

OK,

I managed to fix that blockage by removing php7.3-common

sudo apt remove php7.3-common

then re-running

sudo ncp-dist-upgrade

However now it has stopped at

And my Google-fu has definitely failed me this time.

Does anyone have any ideas how I can fix this?

I have this problem too. Did you manage to solve it?
