FAQ

“Repository […] changed its Version value from […] to […]”

This means that the major and minor version you are running is no longer current and a newer version is available from the repo. From that point, you should no longer receive further updates from the repository (when running apt-get upgrade) unless you allow the updater to switch to the newer version.

To resolve this issue, just run the following command:

apt-get update --allow-releaseinfo-change

Update packages

sudo apt upgrade -y

    In Debian 11 Bullseye the security suite is now named bullseye-security instead of bullseye/updates. So you need to locate the following debian-security lines in the /etc/apt/sources.list file:
    deb http://security.debian.org/debian-security bullseye/updates main
deb-src http://security.debian.org/debian-security bullseye/updates main
    And replace them with these ones:
    deb https://deb.debian.org/debian-security/ bullseye-security main
deb-src https://deb.debian.org/debian-security/ bullseye-security main
  5. Perform a Minimal System Upgrade first
    apt update
apt upgrade --without-new-pkgs

If apt-listchanges is installed, press Q to close its pager with release notes. You will be asked to confirm to stop running services.

  2. Check the currently installed version:
