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.
Probably should have not liked Fedora Silverblue either? Or is it just illogical hivemind hatred?
