[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Kai-Heng Feng (kaihengfeng)]

5.8.0-25.26 is too old. Please make sure system is fully upgraded.

[Asif Youssuff (yoasif)]

Kai-Heng, I am fully updated and I am running the same kernel - see:

[Kai-Heng Feng (kaihengfeng)]

Oh you are using hirsute.

There's a new update in groovy-updates. Please add that to /etc/apt/sources.list.

[Asif Youssuff (yoasif)]

I added groovy-updates.

The issues persist:
