If I recall correctly, I installed my system from 20.04 desktop installation CD. I have been applying updates as they come along. However, even though I have seen many updates, I have not seen any updates for the kernel, which seems quite strange. Here's what I currently have
$ lsb_release --a
No LSB modules are available.

Can it really be true that there have been no updates to the kernel since January?
