@mikagrml I just searched through the web page of grml in order to fix the missing key on my side:
Get:1 http://deb.grml.org grml-stable InRelease [7,782 B]
Err:1 http://deb.grml.org grml-stable InRelease
Sub-process /usr/bin/sqv returned an error code (1), error message is: Missing key DE68E32DCAFFBBBB66D5459CEE1291F5F9382900, which is needed to verify signature.
I wasn't able to find something related to "DE68E32DCAFFBBBB66D5459CEE1291F5F9382900".
What is my error/mistake here?
