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
In my case rvm missed some linux packages, which couldnt be installed without sudo. There were no apt-get install errors at all.
When running rvm install ruby x.x.x with sudo, rvm installed packages required to build ruby and it worked.
Issue - requirements_debian_update_system ruby-2.2.2 error
I also had the same issue. I found info on this link Click Here
I followed this and resolved my issue. Was able to install ruby as
rvm install 2.2
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 ^^
I had the same issue. If none of the other answers work try this. I ran the following command to fix it:
sudo apt-get -f install
Then I remembered that I failed installing a package earlier that day. What this command did was resolve the dependencies on that package and allowed RVM to do its thing.
I was also getting this error when my working directory was inside a mounted dir.
The fix was just to:
cd ~
I figured this out by seeing this at the bottom of a sudo apt-get update
