[lubuntu-devel] Lu 20.10 running 5.4 kernel . . . still???

[Fritz Hudnut]

Walter:

Was running in Lu up until a couple minutes back . . . on to other stuff in
my Sys76 laptop . . . .  But thanks for adjusting the typos . . .  I'll
check into that later.

But, repeating again, this is essentially a box stock install, upgraded via
changing the sources.list from "focal" to "groovy" as I have done a number
of times over the years when working with ubuntu . . . .  The only thing I
have pinned is grub2, but I do run "autoremove" when apt shows kernel
packages and other stuff to remove . . . other than apt I'm not fiddling
with anything under the hood so to speak.

I did mess with the sources.list in my no longer extant U-MATE install to
have both "groovy" and "testing" and that did seem to cause "problems" that
became beyond fixable . . . but my Lu install I always had just "groovy"
and didn't change anything other than focal > groovy . . . .

Anyway, when I get back to the Lu I'll check through your suggestions and
see if anything jumps up . . . .  One of the nice features in LM is that
they used to have a GUI app to show the kernels available and you could
even move ahead of the curve if you felt like it . . . so you could see
"where you are" and "where you could go" . . . .

But, these days the care and feeding of 6 linux installs is enough just to
keep them updated in stock condition . . . I'm not messing around with
stuff, however apt runs the show is what I'm doing.
