sudo cp /var/lib/dpkg/status /var/lib/dpkg/status.bak

Now that you’re equipped to handle this error, you can confidently manage your Debian or Ubuntu system without fear of the dreaded dpkg interruption.

sudo chown -R root:root /var/lib/dpkg/ sudo chmod -R 755 /var/lib/dpkg/

Sometimes, running the command above isn't enough. If dpkg finished configuring but your packages are still arguing with each other, run the following command to fix broken dependencies:

dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

In most cases, the error will be gone. But if the error persists or you see a different message, proceed to the next section.

ls -l /var/backups/dpkg.status.* # locate backups sudo cp /var/backups/dpkg.status.0 /var/lib/dpkg/status sudo dpkg --configure -a

If the standard command freezes, errors out, or fails to run, use these advanced steps to clear out the corruption. Fix 1: Clear the Package Manager Lock Files

while an active installation ( apt or dpkg ) is running.

If a specific software package is causing the loop and refusing to configure, you can force remove that single package to unstick the system.
