Package: cloud-init
Version: 20.2-2~deb10u1
Severity: normal
Dear Maintainer,
after switching from the Debian cloud image "debian-10-generic-amd64-daily-20200510-259.qcow2" to the newer "debian-10-generic-amd64-daily-20200803-347.qcow2" we noticed some automated builds using cloud-init failing.
The exact message printed in /var/log/cloud-init.log is as follows:
2020-08-04 13:10:01,614 - util.py[DEBUG]: Running module apt-configure (<module 'cloudinit.config.cc_apt_configure' from '/usr/lib/python3/dist-packages/cloudinit/config/cc_apt_configure.py'>) failed

oldkey))
ValueError: Old and New apt format defined with unequal values True vs False @ apt_preserve_sources_list
In our configuration we override APT mirrors with local adresses as outlined in the cloud-init documentation which has worked fine in the past:
[...]
# cc_apt_configure
apt:
preserve_sources_list: false
[...]
After some research it seems that a change made a while ago might be responsible for this behaviour:
https://salsa.debian.org/cloud-team/cloud-init/-/commit/2e56b3a489e840c670db4c89633a49ad3374deed
It might be required to specify the default using the newer syntax as "apt_preserve_sources_list" seems to be an outdated way of defining the configuration key according the upstream code:
