Usually, as quickly as a brand new launch is up for grabs, present Ubuntu customers would sometimes get a notification about its availability and might then change to the brand new launch with a single click on.
Nonetheless, a extreme challenge prompted Ubuntu builders to disable the improve immediate. Whereas a handbook improve was nonetheless potential, some high Ubuntu builders need the distro to actively discourage customers from upgrading.
“In case you missed it within the launch notes and listen to individuals asking about it, I wished to let that customers of Ubuntu 20.10 should not being prompted to improve to Ubuntu 21.04…Because of the severity of the difficulty we should not be encouraging individuals to improve at this time limit,” Ubuntu Bugmaster Brian Murray wrote in a post to the Ubuntu developer mailing checklist
The difficulty relating to the shortage of an improve notification is talked about within the launch notes of Ubuntu 21.04, and stems from a bug within the software program (referred to as shim) that enables Ubuntu as well on Extensible Firmware Interface (EFI) geared up machines.
As talked about within the launch notes of the Hirsute Hippo, the present model of shim in Ubuntu 21.04 isn’t appropriate with EFI model 1.10 and can make these computer systems unbootable after the improve.
Murray writes that the builders will allow improve notifications as soon as a brand new model of shim is accessible that works with EFI 1.10.
