Fix error and get back to https with ssl

gistfile1.txt

#The reason is old rubygems.
#So we need to remove ssl source to be able to update gem --system which includes rubygems and so on.
#After this we can feel free to get back to ssl source.

#to temporarily remove secure connection
gem sources -r https://rubygems.org/

#add insecure connection
gem sources -a http://rubygems.org/

#now we're able to update rubygems without SSL
gem update --system

#to remove insecure connection
gem sources -r http://rubygems.org/

#add secure connection
gem sources -a https://rubygems.org/

#Now you're able to update gems using secure connection.
gem update
