According to Microsoft, the bug only affects older versions of Linux-based operating systems, but apparently it has also affected the latest versions of Debian, Ubuntu, Linux Mint, Zorin OS and Puppy Linux.
Fortunately, while waiting for an official fix, it is possible to work around the problem by temporarily turning off Secure Boot, opening the terminal and deleting the SBAT policy with the sudo mokutil -set-sbat-policy delete command. After rebooting, you should turn Secure Boot back on, Ars Technica reports.
