It looks like lolcat hasn't been properly packaged in Solus (it doesn't install all required dependencies). This bug should go to the package maintainer.

In the meantime you can try installing it the ruby way by first removing the Solus package and then doing sudo gem install lolcat.

sudo gem install lolcat worked very well 👍 Thanks
