Made small edits to the test case, given that `nala` is not available on
all releases we test on, and we actually want the binary to be different
rather than an alias to reproduce the bug.
After those tweaks, I was able to reproduce the bug when running from
the archive, and to verify that the proposed package fixes this for all
relases we support.
I am marking verification-done for all releases.
** 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
+ - alias `apt` to `nala` in the system (or better, link the nala binary to
/usr/bin/apt)
- 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.
