Hi, I’ve trying to get the Ubuntu 20.4 (Rpi4) to boot from SSD, by following this guide, however on step 11 when entering zcat vmlinuz > vmlinux, I get a message saying: gzip: vmlinuz.gz: No such file or directory, which means the file doesn’t exist.

I’m thinking maybe this guide is outdated, and the filesystem has changed over the months, or I’m doing something wrong?

Would appreciate help with this, thanks!
