I get following error when trying to install anything with RVM:
Searching for binary rubies, this might take some time. Found remote file https://rvm.io/bina
apt install libc6:amd64 libc6:amd64 libc6 libc6-dev:amd64 libc6-dev libc-dev-bin libc-bin man-db libc-dev-bin libc6-dev:amd64
thats work fine for me ^^
