** Description changed:
- There has been an API change in focal/eoan for python3-apt >= 1.9, and
- the package changer now raises exceptions:
+ [Impact]
+
+ * Regression when applying a package profile through landscape on
+ ubuntu-19.10. Process will stack-trace.
+
+ * The issue is caused by removal of some obsolete methods from
+ python-apt.
+
+ * The backported patch replaces old rewrite_section() by
+ TagSection.write()
+
+ [Test Case]
+
+ * On ubuntu 19.10 (eoan) install landscape-client, run landscape-config,
+ and create a package profile on the account.
+
+ * check /var/log/landscape/package-changer.log for exceptions.
+
+ [Regression Potential]
+
+ * The change has already been published for ubuntu 20.04 and is
+ verified.
+
+ * Patched callsites are only used by package profiles, which would limit
+ the effect of regressions.
+
+ * One possible regression could be in encoding errors,
+ as the new methods handle binary files directly instead of receiving
+ strings. This would imply an issue with python-apt.
+
