Maybe combine apt upgrade with snap refresh?
Lubuntu currently just uses the default Ubuntu tools for package upgrades. Changing that would involve more work, as
apt is kept by default as close to upstream Debian as is possible to reduce workload by Ubuntu developers.
The easiest way to accomplish that would be a front end tool that did both, even if just an alias or script, and given the ease of it, I’m not sure its worth packaging. But that’s just my 2c.
Thanks for the suggestion though (my opinion is just my opinion, others can happily disagree with it!).
snap are two completely different ways to handle packages. That is like mixing beer and milk.
My approach to solve/workaround this: Creating an
alias on all systems which executes
sudo apt update && sudo apt full-upgrade && sudo apt autopurge && sudo snap refresh
