Hi Samuel, tl;dR: Help! I have a tentative fix ready, but in order to see this fixed in Bullseye, someone else has to test the tentative fix by Saturday, 17:00 UTC.

I did the backporting work in a topic branch: https://salsa.debian.org/apparmor-team/apparmor/-/tree/debian-bug-981442 The resulting apparmor binary package has no dependency on python3. Salsa CI will tell us about obvious breakage in other areas, but AFAICT it does not exercise aa-status, so that's not sufficient to make me comfortable uploading this significant dependency change, so close to the freeze, in a package we install by default on any system that has a Linux kernel. I would like this to be tested: 1. build packages from the debian-bug-981442 branch 2. install the resulting apparmor binary package into a testing/sid VM (I don't think a chroot will do) that has no python3 installed 3. ensure step 2 did not install python3 4. ensure aa-status works (compare with how it works in a regular testing/sid system) If you, or someone else, has time to go through this test procedure by Saturday 17:00 UTC, and if the test result is successful, then I'll try hard to upload on Saturday night (UTC), which should hopefully allow this improvement to migrate to testing in time for the freeze :) Thanks for caring about the size of minimal systems installed by d-i! Cheers!

That is getting fixed through #981016, but still better avoid installing the python stack only for aa-status :) Samuel

I'm surprised here. It does seem that Stretch, even as 10.0, does install apparmor and thus python, indeed. But I check for the install size before each Debian release, and did not notice that. Perhaps the apparmor recommendation appeared late in the Stretch process. I'm not sure whether debian-boot was aware that python ended up getting installed. > > or avoid making it hardly depend on python3? > > The only reason why apparmor "Depends: python3" in current testing/sid > is that /usr/sbin/aa-status is written in Python. > > Upstream commit 8f9046b1b179190d0003ae1beacf460ee93c5090, included in > upstream 3.0.0 release, and thus in Debian experimental already, > ported that program to C, which should allow dropping the dependency > on python3.

The only reason why apparmor "Depends: python3" in current testing/sid is that /usr/sbin/aa-status is written in Python. Upstream commit 8f9046b1b179190d0003ae1beacf460ee93c5090, included in upstream 3.0.0 release, and thus in Debian experimental already, ported that program to C, which should allow dropping the dependency on python3. I did not check how hard it would be to backport this commit. There's some more context in https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1865519

Hi Samuel, Thanks for bringing this to our attention. For now I'll focus on trying to understand the scope and severity of this problem.

Could you please confirm whether "in the past" means "in Stretch and older" here, or something else? I'm asking because AFAICT, the chain of dependencies has not changed between Buster and Bullseye: - the Linux kernel images Recommends: apparmor - apparmor depends python3:any > Could you have a look at not installing apparmor by default, For context, the current (Buster, Bullseye) status of enabling AppArmor by default is the outcome of years of work and of a long discussion on -devel@ ("Let's enable AppArmor by default (why not?)" starts at 857eyij4fb@boum.org, August 2017). This of course does not imply it's set in stone nor that we can't improve things :) > or avoid making it hardly depend on python3? I did not check how hard that would be yet.
