Manager not opening

I am useing LMDE2 BETSY Linuxmint Debian. Downloaded latest manager but not starting

This problem seems similar to other forum topics where recent Manager updates requires the updating of other software. Search the forum for topics regarding the updating of “Mono”.

Follow all the commands bit still not working!!!

What is your version of Mono - should be 4.0 or higher.
Read through this topic, one user had to re-download Manager after the Mono update

Its working Now, Thanks a lot
