Meltdown/Spectre patches(Solved)
« on: January 20, 2018, 02:53:18 pm »
Hi Mark,
You recently posted on the peppermint forum a link for users of Pep 6 to update for the above, this I have done, thanks, however just wondering about Ubuntu 14.04 which I run dual booted with Pep 6, how can i ensure that I have the latest patches for the problems with Meltdown/Spectre.

Thanks in advance for your help.

Regards,
Degsy.

I doubt you need to do anything in Ubuntu 14.04 (besides normal updates) as long as you're on their default kernel.

But if you wish, the same HWE update **could** be applied to Ubuntu 14.04 .. just update to the HWE (as per the instructions either in the Peppermint posting or) here:
https://wiki.ubuntu.com/Kernel/LTSEnablementStack

If you want to be sure, post the output from:
Code: [Select]
uname -a
from within Ubuntu 14.04

Hi Mark,
Ran the suggestion as per the website you mentioned, this is the result of the Terminal command.

derek@derek-MM061:~$ uname -a
Linux derek-MM061 3.13.0-137-generic #186-Ubuntu SMP Mon Dec 4 19:09:19 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
derek@derek-MM061:~$

Either the HWE update didn't work, or you haven't rebooted yet to boot the HWE kernel because your currently booted kernel is NOT a patched version.

The standard 14.04 kernel was patched at version 3.13.0-139 (or higher)

and 14.04 with the HWE should be running the patched 4.4.0-109 kernel (or higher)

Reboot, then post the output from:
Code: [Select]
uname -a
again ?

Rebooted, got same response to uname -a.
Repeated sudo apt-get update, got the following error at the end:
W: Failed to fetch http://ppa.launchpad.net/lestcape/cinnamon/ubuntu/dists/trusty/main/binary-amd64/Packages  403  Forbidden

W: Failed to fetch http://ppa.launchpad.net/lestcape/cinnamon/ubuntu/dists/trusty/main/binary-i386/Packages  403  Forbidden

E: Some index files failed to download. They have been ignored, or old ones used instead.

Advice please

Okay can you explain:-

Quote
Ran the suggestion as per the website you mentioned

and post the output from:
Code: [Select]
ls /etc/apt/sources.list.d

And have you attempted to install Cinnamon in Ubuntu 14.04 at some point ? .. is it still installed ?

Hi,
derek@derek-MM061:~$ ls /etc/apt/sources.list.d
lestcape-cinnamon-trusty.list       teejee2008-ppa-trusty.list
lestcape-cinnamon-trusty.list.save  teejee2008-ppa-trusty.list.save
derek@derek-MM061:~$
Initially I ran sudo apt-get update, then sudo apt-get dist-upgrade, then rebooted.
I then copied and pasted the lengthy command into the Terminal and proceeded, it seemed to be going ok as the 4.4.0-109 number appeared several times during the process, however after reboot and uname -a the result was as previously given.
I have not knowingly attempted to install cinnamon.

then
Code: [Select]
sudo rm -v lestcape-cinnamon-trusty.list.save
then
Code: [Select]
sudo apt-get update
then
Code: [Select]
sudo apt-get dist-upgrade
if that command finishes without error, REBOOT

Then post the output from:

Good god you have a LOT of old kernels installed.

First try running:

Hold on .. did you say this was a dual boot setup with 2 Linux distros ?

If so, run:
Code: [Select]
sudo update-grub
in BOTH distros.

Then boot into 14.04 and post the output from:
Code: [Select]
uname -a
