Comment 94 for bug 1779827

Thank you Wes Newell for your reply.

I only installed ubuntu on this computer (big big big mistake) I do not have the grub menu at start.

After typing many commands which I did not understand ubuntu started. I have lost the sound however and now I am afraid to turn it off. If I run:

dpkg -l | grep linux-imagerc

linux-image-4.15.0-20-generic 4.15.0-20.21 amd64 Signed kernel image generic
rc linux-image-4.15.0-22-generic 4.15.0-22.24 amd64 Signed kernel image generic
ii linux-image-4.15.0-23-generic 4.15.0-23.25 amd64 Signed kernel image generic
ii linux-image-4.15.0-24-generic 4.15.0-24.26 amd64 Signed kernel image generic
ii linux-image-generic 4.15.0.23.25 amd64 Generic Linux kernel image

And currently:

uname -r:
4.15.0-24-generic

Which commands should I run to purge that kernel and run the previous one? Should I do it from tty? or from the current session? Should I wait for an update or will that make it worse...
