This ties in with the upstream bug on the Maria jira

https://jira.mariadb.org/browse/MDEV-9781

[Daniel Bartholomew (dbart)]

This looks like network issue to me. The message "key CBCB082A1BB943DB can't be retrieved" indicates that the local server wasn't able to talk to the keyserver.

Unless the error message contains something along the lines of "The repository is insufficiently signed..." the error is not related to https://jira.mariadb.org/browse/MDEV-9781

Some background info:

The log message is the output of the following command that the config-changed hook runs:

sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db

Successful output when running the above manually looks like this:

Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.BH1UjsdhDR --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xcbcb082a1bb943db
