[bitfolk] Kernel upgrade (Debian 10.2)

Hello, I'm having some issues upgrading software on my Bitfolk-hosted Debian 10.2 server. I ran 'sudo apt --fix-broken install' after being told to do so to fix unmet dependencies. Running this gives the following error: "This version of the GNU libc requires kernel version 3.2 or later. Please upgrade your kernel before installing glibc." Is there an easy answer to the obvious question what kernel to upgrade to? And would this even solve my issues? I currently appear to be running 2.6.32-5-686-bigmem. I've had this server for years and I might have added one quick fix for a specific problem too many over the years. Here's the content of /etc/apt/sources.list: deb http://apt-cacher.lon.bitfolk.com/debian/ftp.uk.debian.org/debian/ stable main contrib deb-src http://apt-cacher.lon.bitfolk.com/debian/ftp.uk.debian.org/debian/ stable main contrib deb http://apt-cacher.lon.bitfolk.com/debian/ftp.uk.debian.org/debian/ stable-updates main contrib deb http://apt-cacher.lon.bitfolk.com/debian/security.debian.org/ stable/updates main contrib Thanks!
