The procedure is as follows:
- Open your terminal application.
- For remote server login using the ssh command:
ssh user@debian-12-server
- Add or enable contrib repo to /etc/apt/sources.list using sed command:
sed -r -i'.BAK' 's/^deb(.*)$/deb\1 contrib/g' /etc/apt/sources.list
Here is how it looks when contrib is appended to each line:deb http://deb.debian.org/debian bookworm main non-free non-free-firmware contrib deb http://deb.debian.org/debian bookworm-updates main non-free non-free-firmware contrib deb http://deb.debian.org/debian-security/ bookworm-security main non-free non-free-firmware contrib
- Update apt repo database, type:
apt update
- NOTE: If you have recently installed a new Linux kernel update on Debian 12, you must reboot your machine or virtual machine. Failure to do so may result in compilation errors by the zfs-dkms package, as the command will try to use header files from the newly installed Linux kernel and fail.Install zfs package on a Debian Linux 12:
apt install linux-headers-amd64 zfsutils-linux zfs-dkms zfs-zed
Are you using a cloud server with cloud Linux kernel? Try:
apt install linux-headers-cloud-amd64 zfsutils-linux zfs-dkms zfs-zed
- Test it by running zfs version command:
modprobe zfs #<--load the module
zfs version
Outputs:zfs-2.1.11-1 zfs-kmod-2.1.11-1
