Question

linux

Colleagues, good time!
Evil fate forced me to face Astra Linux Smolensk 1.6. In good faith - for nothing!
But now I had to ...
Now the task is to update the kernel of the Smolensk 1.6 system to 5.10.
Everything seems to be simple and clear. On Linux. But not in Astre.
As a manual, I used https://wiki.astralinux.ru/pages/viewpage.action?p...
With grief, I deployed the virtulka on KVM in half, did all the steps to "Installing the linux-5.10 kernel"
And then ... Well, there is no such kernel versions!
Has anyone come across this ambush?
We need a 'hard' kernel 5.x for Astra Linux Smolensk with all the stupid bells and whistles and approved by our guardians of cheburnet security.
