### Bug Description What is the expected behavior when a virtual package is listed in stage-packages in snapcraft.yaml? For example [libasound2](https://github.com/canonical/checkbox/blob/main/checkbox-core-snap/series24/snap/snapcraft.yaml#L290) in checkbox, it is a virtual package in [noble](https://packages.ubuntu.com/noble/libasound2). ``` $ sudo apt install libasound2 [sudo] password for vincent: Reading package lists... Done Building dependency tree... Done Reading state information... Done Package libasound2 is a virtual package provided by: libasound2t64 1.2.11-1ubuntu0.1 (= 1.2.11-1ubuntu0.1) liboss4-salsa-asound2 4.2-build2020-1ubuntu3 You should explicitly select one to install. E: Package 'libasound2' has no installation candidate ``` According to the build log for checkbox24, the behavior seems to be different on [ARM64](https://github.com/canonical/checkbox/actions/runs/16202677370/job/45745393365) and [AMD64](https://github.com/canonical/checkbox/actions/runs/16202677370/job/45745393319). If you search for "asound", you will find that it installed both packages on arm (which is also not correct since these 2 packages conflict with each other), but only libasound2t64 on amd64. Another weird thing is that the [build](https://github.com/canonical/checkbox/actions/runs/15216444593/job/42803001251#logs) on AMD64 on May 24th, it installed both packages, which is different from the current build. ### To Reproduce 1. git clone https://github.com/canonical/checkbox.git 2. cd checkbox/checkbox-core-snap/ 3. ./prepare.sh 24 4. cd series24 5. snapcraft ### Environment -
