External Email - Use Caution
Hello Antonin, I’ve found a few posts that seem to indicate you can upgrade as well as downgrade the kernel (and its dependent packages) by editing the /etc/apt/sources.list to point to the Ubuntu distribution you want (and then running update, upgrade, dist-upgrade commands).. Not sure what the previous Ubuntu distribution name was for you, but this post, https://sypalo.com/how-to-upgrade-ubuntu, lists the distributions as, 18.04 - bionic 18.10 - cosmic 19.04 - disco 19.10 - eoan 20.04 - focal 20.10 - groovy While that post gives the example of *upgrading*, this post gives the example of *downgrading*, https://linuxconfig.org/how-to-downgrade-ubuntu-linux-system-to-its-previous..., but I think they are essentially doing the same thing, i.e. it’s a function of the distribution name listed in /etc/apt/sources.list. Note that even if you are downgrading the kernel, as far as the apt package manager is concerned you still have to run the various “upgrade” commands to change the distribution to a different one even if it is older. - R.

Hi there!
thanks for the answer and your searches.
Actually I solved my issue, basically the last upgrade created a circular depency issue in my nvidia driver packages, causing issues with graphical applications. I think this, in the end, is unrelated to the kernel upgrade.
Thanks again for your time!
Best

I use to have a perfectly working freesurfer installation on my Ubuntu 18.04 LTS machine, until that doomsday where I installed updates as recommended by ubuntu itself.
Now, each time I run freeview, I get the following error:
Aborted (core dumped)
I reinstalled freesurfer from scratch, fixing nothing.
I think Ubuntu did a kernel upgrade; now I have a uname -r output = 5.4.0-52-generic I think it used to be 49 instead of 52 before the upgrade, but I am not sure.
Do you know of any patch fixing this, by any chance?
Thanks for your lights
