Hi, sorry really struggling to flash an ubuntu bootloader to transition from my old Macbook Pro to new framework laptop. I’ve tried everything I can see suggested on the forum including opening through sudo, re-downloading ISO, using an older linux ISO, rebooting, re-formating my (brand new) USB stick, but to no avail. Error code is below, if anyone could help me that would be amazing. Thanks in advance, Donald index.js:2 \_\_\_\_\_ \_ \_ | _**| | | | | | **| |_ _** | |** \_\_\_ \_ \_\_ | **|| / | ’ \ / \_ \ '| | |**| || (__| | | |**/ | \_**_/ \__\_\_\_|_| |_|\_\_\_|_| Interested in joining the Etcher team?
