After updating from Checkmk 2.4 to 2.5, you need to either source your .profile or log out and back into your shell sessions:

source ~/.profile

If you have no open shell sessions after the update, you may ignore this.

This manual intervention is required because Checkmk 2.5 added new environment variables to .profile for special agents and active checks, but the update process cannot modify your currently active shell environment.
