Looking for some help to get back on the normal kernel stream for PM7 respin x64.
I recently tried a Low Latency kernel for attached music devices/synthesizers midi etc..and I'm having difficulty getting back to the normal kernel.
I've tried via the mint-updater kernel section and mismatch errors occur at 98% 
Any help would be greatly appreciated.

regards,
acer

What is returned by:

Code: [Select]

sudo apt-get -s remove --purge linux-image-lowlatency linux-image-4.4.0-87-lowlatency linux-signed-image-4.4.0-87-lowlatency

and

Code: [Select]

sudo apt-get -s install linux-signed-image-generic

and

Code: [Select]

[ -d /sys/firmware/efi ] && echo UEFI || echo BIOS

The first two commands won't actually remove or add anything, they're just a dry run to see what WOULD happen if we actually made the changes.
The last command is to see if Peppermint was installed in UEFI or Legacy BIOS mode.

And do you know how to boot into the generic kernel ?

sorry forgot to answer your last question.
No, I don't know how to boot into generic kernel 

I only have one kernel in use according to the mint-updater 4.4.0-87

[PCNetSpec]

Okay first we're gonna have to make sure you can boot to the generic kernel .. because you need to be booted into this kernel to remove the lowlatency kernel.

So...

Shut down your PC

Power ON your PC, and as soon as the BIOS POST screen (manufacturer logo) disappears, hit and hold the "Shift" key .. you should be presented with the GRUB menu.

On the GRUB menu use the down arrow key to select "Advanced" .. and hit Enter.

Use the arrow key to select Peppermint GNU/Linux, with Linux 4.4.0-87-generic .. and hit Enter to boot that kernel.

Once you're at the desktop, run:

Code: [Select]

uname -a

and post the output back here so I can see you got it right.

Code: [Select]

Linux HP-Notebook 4.4.0-87-generic #110-Ubuntu SMP Tue Jul 18 12:55:35 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Yeah done that before, just not in ages.

[PCNetSpec]

Cool .. okay, whilst booted to the generic kernel, run:

Code: [Select]

sudo apt-get remove --purge linux-image-4.4.0-87-lowlatency linux-signed-image-4.4.0-87-lowlatency

the reboot without doing anything in GRUB,

And post the output from:

Code: [Select]

uname -a

again

B I N G O ! Back to normal

I should have remembered this, it's just been a hectic friday!
Will mark as solved..
Cheers PCNETSpec..enjoy your evening and good karma be with you.

[PCNetSpec]

Yep, all done...

You have a good evening too acer

[acer]

Should I be concerned on the linux-libc-dev version?
Does it also need reverting back also or will that just change automajically with the next kernel update?

Code: [Select]

ii  linux-libc-dev:amd64      4.4.0-89.112

[PCNetSpec]

No that's the right version.

I have the same version and I'm on the 4.10 kernel series .. in fact it's the only version in the repos

[acer]

Yeah sorry, realised this later than the post and forgot to update/remove post.
Thanks again for the confirmation 

[PCNetSpec]

No worries
