This is a bit of a wrong recipient for your complaint - apt does not manage snap packages, the deb2snap packages implement that in their maintainer scripts - but let me say that this behaviour is in line with the behaviour expected for transitional packages.
For deb2deb transitional packages, apt even implements special logic for that behaviour: If a package is manually installed but becomes a transitional package, the manual bit moves to the new package replacing it and the transitional package becomes autoremovable. The behaviour for deb2snap packages is in line with that, with the exception that these do not become automatically removable. ** Changed in: apt (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/2087320 Title: Removing an APT to snap transitional package does not remove the snap Status in apt package in Ubuntu: Invalid Bug description: Environment: Xubuntu 24.04.1 LTS x86-64 apt 2.7.14build2 snap 2.65.3+24.04 Steps to reproduce: Open a terminal and enter these commands df sudo apt install chromium-browser sudo apt purge chromium-browser df Actual results: APT does not offer to remove the snap after removing the transitional package. Expected results: APT removes the snap and archived older versions, either on its own (because nothing depends on it) or by displaying the appropriate snap command to run afterward. Additional notes: During these steps, I observe bug #1958811, in which apt install displays the size of only the transitional package proper, not the snap it installs.
