OS: Ubuntu 24.04, Permissions: Read write (chmod 777 and chown to my account) User: non root (with root i getting do not run as root! error)
Compiled myself manually, no luck, still /mnt/linux permission denied (even if i compiled in home/user/poco/linux-next)

Compiling linux (not next) is successful but linux-next not

Creating files in /mnt/linux without root works
