Debian 11 APT Sources List File Upgrading to Debian 11 from Debian 10
Newly modified /etc/apt/sources.list file. # bullseye-updates, previously known as 'volatile' Now replace the original ‘ Buster‘ lines with the following lines in the /etc/apt/sources.list file to ‘ Bullseye‘ as seen in the below screenshot. Original /etc/apt/sources.list Debian 10 APT Sources List File $ sudo cp -v /etc/apt/sources.list /root/ Assuming a standard /etc/apt/sources.list file.įirst, make sure to backup sources.list file and then do changes as shown. Now it is time to do is prepare the system to look at the new repositories for ‘ Bullseye‘. Once updates finish, you need to reboot the system to apply the kernel and other updates: $ sudo systemctl reboot To completely update the system issue the following command as root or with the ‘ sudo‘ utility: # apt update Personally, recommend that the current system be completely updated before attempting a distribution upgrade but this is likely unnecessary. If a backup/tar file can be made, it is strongly recommended before continuing.ĭisclaimers out of the way, let’s begin the upgrade process.
The first step before the upgrade is to back up any important data! While this is often unnecessary, the one time that a backup isn’t made, something will fail and break the system.
An upgrade the other day took about an hour due to slow download speeds from the Debian US repository, likely because a lot of people are upgrading at the moment. For those wishing to upgrade from Debian 10 Buster to Debian 11 Bullseye, the process is very simple but does take a while depending on the connection speed to the Internet.
