Hello All,

I started getting this kernel build error yesterday on the Stable branch. Not sure how to get around it. Any insight much appreciated.

Thanks Much,

Issue resolved with some online help:

I added the backports repository and successfully installed
6.5.0-0.deb12.4-amd64. Apt upgrade was still hanging and trying to configure 6.1.0.18 though so I used:

apt-get --force-yes remove 6.1.0-18-amd6

Voila! No more 6.1.0.18 hanging and erroring out and now I have:

uname -r
6.5.0-0.deb12.4-amd64
