[aur-general] Problem with makechrootpkg

I am trying to run makechrootpkg -r /aur -- -i in the dir that contains the PKGBUILD /usr/bin/makepkg: line 461: /dev/null: Permission denied I redid the chroot with mkarchroot -f /aur/root base base-devel sudo to see if that would help but still the same error. I tried another package earlier and it gave the same error, thought maybe there was something else wrong.
