** Description changed:
+ [ Impact ]
+
+ If `apt` is masked by other helper tools, such as `nala`, as seen in the
+ original description, `apt list --installed` will return data in a
+ different format. This will cause the Pro Client to fail to parse the
+ data, and break.
+
+ The Pro Client should not be relying on CLI output when there are Python
+ bindings available to perform the same task - and python3-apt provides
+ ways to list installed packages.
+
+ The fix to this bug is to rely on the programmatic integration with APT
+ instead of calling the CLI.
+
+
+ [ Test Plan ]
+
+ Listing installed packages is part of the regular operation of the Pro
+ Client in many scenarios covered by the integration / acceptance tests.
+
+ For this particular issue:
+ - Launch a container for the release to be tested
+ - install nala
+ - alias `apt` to `nala` in the system
+ - see it fail
+ - install the package from -proposed
+ - see it does not fail anymore
+
+
+ [ Where problems could occur ]
+
+ Switching from the CLI call to python3-apt brings the risk of wrong
+ implementation of the integration, which would lead to a different
+ package list to be returned by python3-apt. The regression potential is
+ mitigated by extensive testing - unit, integration and acceptance tests
+ rely on this functionality.
+
+
