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.
The only reason I’m still using Canonical’s bullshit after they tried to kill Unity, tried to force Snap on me and put ads in the shell is because of Rudra Saraswat. His Ubuntu Unity flavor is really good once you remove snapd.
