The "Failed to start casper-md5check Verify Live ISO checksums" error typically occurs on Linux systems, particularly Linux Mint and Ubuntu-based distributions, after a system update or during boot. This service is designed to verify the integrity of a Live ISO system by checking checksums against a file located at /cdrom/md5sum.txt, but it is unnecessary on installed systems where the Live ISO is no longer in use. As such, the error is generally non-critical and does not affect system functionality, though it can be disruptive during boot.
The most common and recommended solution is to disable the service to prevent the error from appearing at boot. This can be done by running the following commands in a terminal:
Bash:
sudo systemctl disable casper-md5check.service
sudo systemctl stop casper-md5check.service
sudo systemctl mask casper-md5check.service
These commands disable the service from starting at boot, stop any currently running instance, and mask the service to prevent manual activation. After executing these commands, a system reboot will resolve the issue, and the error should no longer appear in the boot logs.
