If your distro is not {arch, debian, fedora, freeBSD, gentoo, venom, solus} based fetch-master-6000 wont be able to detect number of packages In that case you have to specify number of packages yourself
Solus is already supported For example:
On Solus (eopkg) command to list all istalled packages is:

eopkg list-installed

to count packages pipe the list to wc -l

eopkg list-installed | wc -l

make it an alias to avoid typing it everytime

alias fm6000='fm6000 -p $(eopkg list-installed | wc -l)'

Similiarly for other distros

fm6000 -p $(pacman -Q | wc -l)

output
