Linux kernel image Update problem in Ubuntu mate 21.04 daily build.How to update?

I am using ubuntu mate 21.04 (Hirsute Hippo) daily build .I am running it inside virtual box 6.1
I have allocated 2 cores and 2gb ram to the virtual box.
I updated the system using "sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade -y && sudo apt autoremove -y"
I saw Linux image update from to different versions
There are 3 versions

  1. linux-image-generic/hirsute-proposed amd64 [upgradable from:]
  2. linux-image-generic/now amd64 [installed,upgradable to:]
  3. linux-image-generic/hirsute amd64

I want to update to the hirsute-proposed version (linux-image-generic/hirsute-proposed amd64 [upgradable from:])
Even after rebooting several times I can't seemed to update to the hirsute-proposed version. How can I update to that version?

Hi @jofena9870, welcome. Have you enabled the 'hirsute-proposed' repo? If not do so and see if you are able to upgrade.

EDIT: Sorry, saw in screenshot you have already enabled the -proposed.

To install from -proposed, use the -t option as

sudo apt install linux-generic -t hirsute-proposed
