I updated checkmk raw docker from

  • 2.0.0p9

to 2.2.0p14 with the update steps:

  • 2.0.0p39
  • 2.1.0p37

Web UI is working fine. But if i Want to apply some configuration. I get th error:

An error occurred: Error creating configuration: MAC check failed

This seems a known fixed issue: Werk #13641: Fix ‘ValueError: MAC check failed’ error in “Rewriting rulesets” phase of update

but it seems i dont need to do anything?

Compatibility	Compatible - no manual interaction needed

Not sure how to proceed.

I could trigger the error message under “Setup > General > Passwords”. So i digged further and found the file:

cmk/var/check_mk/stored_passwords

This file was in cleartext and on my dummy fresh instance in binary. So i renamed the file and it got recreated with the content and the error message with MAC dissapeared. :slight_smile:
