Kernel Update Woes

jackdanielsesq · 2018-08-07 08:48

Greetings all

My best, longest living O/S is now garbage - stuck in infinite-Control-D-loop
Tried everything ... did notice some weird audio problems after a reboot

Jack

Edit

Any ideas that work with this distro would be appreciated - moving my post does not count

Sorry, your post didn't look like a support request before you edited it, so it has been moved to the General section. In order to help you, we would need some information about the problem, such a particular error messages, hardware specs, etc ... Are you really sure, it is connected to the kernel update ?

Yes - it occurred after the first reboot - first Pulse went awry, did another reboot, and that was it, the system is not accessible
The above image was 18MB - the latest image on 2.5 # 2 is 38MB - 8 days later ... why?

I think that the size of updated image isn't a problem.

I have a similar problem, my laptop also not boot correctly.

The OS boot into emergency mode, then ask root password and login. Then, I press Ctrl+D, and it proceed booting normally.

Did your system also boot in emergency mode? If yes, try to login as root and check the red lines on the output of

# journalctl -xb

Or login as root and then type

# exit

Did you notice this issue after the latest kernel update ? In about last 7 days ?

In my case, it started after I installed the "latest Kernel available" using the instructions on the Q4OS documentation. The latest kernel available is 4.0.17 (somethink like this, I didn't remember now) and after this update I always get stuck at "You are in emergency mode bla bla bla" dialog. Ctrl+D don't work, I can't type anything, the system don't boot.

I am using the second entry of Q4OS in "Advanced options for Q4OS" entries on GRUB, it uses the 4.0.9 kernel (i think it is), the system shows a message about mounting Swap partition and also boot into Emergency mode, but I can type Ctrl+D to exit and then system continues boot normally. And the Swap partition is also mounted sucessfully after boot.

@BrJPedro
We assume, you have followed these instructions https://q4os.org/dqa011.html#system.5 to install the latest kernel from backports. As you can see, there is a warning in the instructions:

"We recommend to use reliable and deeply proven default Q4OS/Debian kernel, there isn't too much reasons for ordinary users to use newer kernel. Keep in mind, the latest kernels are not so secure as the rock stable and exhaustively tested default Debian kernel ..."

We suppose, the issue you mentioned is not connected to the OP. Anyway, thanks for the hint.

@q4osteam Yes, I followed these instructions.

I checked all 4 kernels available at "Advanced options for Q4OS" in Grub.
If I use 1st (4.0.17 I think) and 4th (4.0.9-5) entries, the system stucks at Emergency mode.

But if I use second (4.0.9-7) or third (4.0.9-6), the system show the Swap warning and boots into Emergency Mode, but if I press Ctrl+D the boot proceed sucessfully.

I suggest to the OP to also try to use the others entries in GRUB.

PS: As I am not being able to use the latest kernel, is there a way to I uninstall it? :v

Yes, run in terminal:
$ sudo apt autoremove linux-image-4.0.17-amd64 linux-image-4.0.9-5-amd64
