Ubuntu/Mint Error: The Volume boot is low on space

Case: Updating a Linux Mint 20 installation successfully, rebooting and receiving a pop-up message: Error: The volume "boot" has only 54 MB disk space remaining.


The /boot/ partition is used for boot loader files (e.g., kernels, initrd). During update, kernel headers are updated but their older counterparts remain.

Run sudo apt autoremove

autoremove deletes files, downloaded by updates, that no longer have dependencies, such as the kernel headers stored in /boot/.
