Problem description

when I try to install or update packages using pkg, it show me the following error:-

/data/data/com.termux/files/usr/bin/pkg: line 197: TERMUX_MAIN_PACKAGE_FORMAT: unbound variable

Steps to reproduce the behavior.

All I found in the internet is to use apt instead of pkg.

What is the expected behavior?

It should install or update packages.
