Package: cloud-init
Version: 18.3-6
Severity: normal
Dear Maintainer,
I'm trying to add some other repositories under
/etc/apt/sources.list.d using the following 10_fuss.cfg file in
/etc/cloud/cloud.cfg.d/:
apt:
preserve_sources_list: true
sources:
fuss-buster.list:
source: "deb http://archive.fuss.bz.it/ buster main"
key: |
-----BEGIN PGP PUBLIC KEY BLOCK-----
...
it work fine and add the list the first time cloud init is run, but in
a later run cloud-init reprocess this file (like after adding a new
ssh key for accessing the server) the source line is appended (the
same happens also if preserve_sources_list is false). So I got
duplicated lines with APT complaining
Looking at the logs in cloud-init.log I traced the problem inside the file:
/usr/lib/python3/dist-packages/cloudinit/config/cc_apt_configure.py
where in the function add_apt_sources, at line 624 there is a:
util.write_file(sourcefn, contents, omode="a")
that write the file in append, giving a duplicate line.
The problem is present also, at the time of writing, in the official
upstream sources, here:
https://github.com/canonical/cloud-init/blob/master/cloudinit/config/cc_apt_configure.py
I think changing the code to omode="w" should solve this problem.
