so I'm trying to install heroku toolbelt with
wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh
but, I get this error:
Ign http://packages.medibuntu.org precise/non-free Translation-en_US Ign http://packages.medibuntu.org precise/non-free Translation-en Fetched 910 B in 14s (63 B/s) Reading package lists... Error!
W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://dl.google.com stable Release: The following signatures were invalid: BADSIG A040830F7FAC5991 Google, Inc. Linux Package Signing Key
so I tried to use sudo apt-get install, and I get the same exact error. How do I fix this and install heroku toolbelt?
