I know this is probably a noob question, but I can't seem to install opensh

I installed inception, installed the wget utility, and then have tried to install opensh multiple times but get the following error:

Error: certificate common name 'www.endno.de' doesn't match requested host name 'endo.de'. To connect to 'endno.de' insecurely, use '--no-check-certificate'
Unable to establish SSL connection

This is what i've been typing in to terminal:
wget -O opensh_1.00_armel.deb https://endno.de/~itsnotabigtruck/in...1.00_armel.deb

I have also tried putting http:// rather than https:// and that comes up with the same error :/
