Doesn't build out of the box

Hello, I'm new to linux and I'm setting ubuntu up on my Macbook Pro 15.

When I run sudo make I get this:

$ sudo make
make -C /lib/modules/6.2.0-32-generic/build M= modules
make[1]: Entering directory '/usr/src/linux-headers-6.2.0-32-generic'
  SYNC    include/config/auto.conf.cmd
  LEX     scripts/kconfig/lexer.lex.c
/bin/sh: 1: flex: not found
make[3]: *** [scripts/Makefile.host:9: scripts/kconfig/lexer.lex.c] Error 127

@MCMrARM Do you still maintain this? Please let me know if there's a fork I can go to instead. Thank you!
