[SOLVED] Unable to install Kernel 4.15.0.38-Generic

Post by Jodel-D18 » Sat Oct 27, 2018 7:14 am

Apologies for the length of this post, but I didn't want to omit what may be important information to help identify the issue.

My main desktop PC (running Mint 19) has not been able to accept any updates to the Linux kernel since Kernel: 4.15.0-36-generic.
I have another laptop also running Mint 19 which has not encountered any such update issues and is now running Kernel: 4.15.0-38-generic.

My PC build is nothing particularly exotic and is as follows:

Code: Select all

uname -r

Whenever I’m notified of an update, the process terminates with an error message – for example, see below for a report of an update which included Chrome and Firefox amongst others (in the interest of brevity, I’ve cut out parts of this):

I’m very much a Linux novice, and it looks as though the Kernel 4.15.0-38-generic has been downloaded, but for whatever reasons not installed. I have not (consciously) moved or deleted any files such as the dkms.conf file. Can anyone shed any light on this at all? I’d appreciate any guidance which may help me resolve the problem.

Check the source folders in /var/lib/dkms/* as one or more might be missing the dkms.conf file
Replace the * with package/version#

Re: Unable to install Kernel 4.15.0.38-Generic

JeremyB, thanks for the prompt response. There are indeed a couple of sub-directories in my /var/lib/dkms created I think during my (failed!) attempts to get my TP-Link wireless USB stick working, but each of these do contain a short dkms.conf file.

There is not a dkms.conf file for the 4.15.0.38 kernel as far as I can see (nor for the 4.15.0.36 for that matter - which is working fine).

Do you happen to know if there is there a 'standard' dkms.conf file for the kernel which I can download, or can I create one via nano or similar editor?

BTW: Thank you if you tidied up my initial post - I wasn't sure how to present the information.

If it helps:

Code: Select all

dkms status
/var/lib/dkms/mt7610u_sta/1.0/source
/var/lib/dkms/rtl8812AU/5/source
/var/lib/dkms/rtl8814au/4.3.21/source

You could remove them if none of them worked for your wifi, use sudo dkms remove package/version --all
You can get the package from the directory name in /var/lib/dkms and the version number will be a folder name within the package folder, normally you get get the dkms package name and version from results for dkms status but that command will likely fail also

Re: Unable to install Kernel 4.15.0.38-Generic (SOLVED)

Post by Jodel-D18 » Sat Oct 27, 2018 9:26 am

Now solved! Thank you.

As suggested I removed the wireless network packages, then ran

Code: Select all

sudo apt-get dist-upgrade
I rebooted and now

Code: Select all

uname -a
results in:

Linux midi-tower 4.15.0-38-generic #41-Ubuntu SMP Wed Oct 10 10:59:38 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Looks like all is working again, so thanks for your help :)
