Try running sudo apt-get update separately on the command line. Your Ubuntu may be old, and its repositories may be obsolete. Therefore, apt-get update itself may not work on your machine.
To resolve this issue, run the following commands:
# Disable RVM from trying to install necessary software via apt-get rvm autolibs disable
If you still encounter errors, see if you can do apt-get install directly without performing apt-get update (which fails):
If this also does not work, insert your apt-get update output.
