Installing Linux packages

Trying to follow the section in the NomadBSD handbook for installing Linux packages, however I get two error messages:

# service abi start
abi does not exist in /etc/rc.d or the local startup
directories (/usr.local.etc/rc.d), or is not executable

# pkg install linux-sublime
[1/27] Installing linux_base-c7-7.9.2009...
Cannot install package: kernel missing 64-bit Linux support
pkg: PRE-INSTALL script failed

Using version 130R-20210508 of NomadBSD.
