For our distro Ubuntu Budgie we have been supporting our classic distro-specific snap ubuntu-budgie-welcome for 18.04/20.04 and later.
Our agreed support arrangements for 18.04 ends this April (3 yrs support) and as such we no longer want the extra complexity to check newer versions of our classic snap works against this old flavour version nor release compatible versions of the snap for this old version.
We build ubuntu-budgie-welcome with core18 specifically for 18.04 support (32bit + 64bit). We would now like to move to core20 and thus 64bit only
Is there a recommended method to stop support for our snap - maybe removing the snap from the stable/ubuntu-18.04 track? I would rather not just let the snap “fester” with no more updates.
Should we just release one last version of the snap on the stable/ubuntu-18.04 track with a dialog displayed when the snap is run saying that “this flavour is now end-of-life - please upgrade to 20.04” ?
