Ubuntu Core Desktop will not be released alongside Ubuntu 24.04 LTS in April, as originally hoped.
Canonical doesn’t go into details about what specific issues need resolving. One imagines, given that the first Ubuntu Core Desktop release was going to be a preview and not a recommended download, it’s a myriad bugs/difficulties — ones not easily sorted.
My belief is use the appropriate tool for the job, without inserting ideology into it. If I find Flatpak nice, I will use it. Same goes for Snap or AppImage. Linux package method wars are as dumb as Cola Wars or console/smartphone wars.
I do the same but I still have a preference. I agree it’s dumb.
