CheckMK-Docker after Update to 2.2.0 => Error 500

bastimm13 · May 25, 2023, 9:46am

CMK version: 2.2.0 Docker -Raw
OS version: Ubuntu 22.04

Error message: “Internal Server Error 500” on GUI

Hello,
I am new to checkmk… yesterday I updated my running checkmk to 2.2.0
=>
docker stop checkmk
docker rm checkmk
docker container run -dit -p 8095:5000 -p 8000:8000 --tmpfs /opt/omd/sites/cmk/tmp:uid=1000,gid=1000 -v monitoring:/omd/sites --name checkmk -v /etc/localtime:/etc/localtime:ro --restart always checkmk/check-mk-raw:2.2.0
On my server there is a nginx forward to port 8095 and this worked until this update…
If I open domain.de/cmk/check_mk/ => I get a Error 500…

Can somebody help me to find this error?
Thanks in advance

I have ran into the same issue, after upgrading my Checkmk docker to 2.2.0p2.cre the web GUI is no longer accessible and I am receiving a HTTP Error 500.

I check the web.log in the docker container /opt/omd/sites/cmk/var/log/web.log and I get the following entry

Checking the status through the command line it looks like everything is up as well.

I am still getting email notifications for events/alarms so it appears like the back end is working, just the web gui seems to be having issues.

Edit: I was successful in launching a new clean docker image with 2.2.0p2.cre so this appears to only affect upgrades. I upgraded the docker image from 2.1.0p28 to 2.2.0p2

Looks like I was able to get back into the web gui by going into the docker image and running

OMD[cmk]:~$ cmk-update-config -vvv --debug
parsed arguments: Namespace(debug=True, verbose=3, conflict=<ConflictMode.ASK: 'ask'>)

  Some steps may take a long time depending on your installation.
  Please be patient.

After that the web GUI came back. Had to re-run some discoveries on host but eventually everything returned back to normal.

Hi,
just tested it again…
I get this error:

Bacon-O · June 15, 2023, 3:29pm

I would not considered myself an expect on Checkmk, but I suspect the issue is that you are still the root user inside the docker image and not the site user. Try switching to the site user and running the cmk-update-config command again.

For me my site is called “cmk”

THX , didn’t know that I had to switch to cmk user…

THANKS in advance!!

bastimm13 · June 16, 2023, 4:15am

after pressing “c” I got this error:

bastimm13 · June 16, 2023, 4:38am

Perhaps it is the best to delete all my settings/Servers and restart with a clean install?

Matthew1 · August 3, 2023, 6:05am

Did you solve these issues? I have the same I would not do a clean install of my server because I have a lot of data into.
