Re: `apt list` output question

[IL Ka <kazakevichilya@gmail.com>]

What is the meaning of the "stable,now" string?

Here are two answers from the Debian developer 

https://unix.stackexchange.com/questions/408944/understanding-apt-list-output

https://unix.stackexchange.com/questions/403177/what-is-the-format-of-the-apt-search-output-on-debian-ubuntu

Btw, "apt" output is not stable nor well documented. It is recommended to use "apt-get" for the scripting purposes or, in your case, "dpkg --list" or "dpkg-query".
