Thread: Not able to run yum on Ubuntu.

i trying install command line client amazon emr docs.

using command:

code:

$sudo apt-get install ruby-full

but error

code:

loaded plugins: fastestmirror, security      loading mirror speeds cached hostfile      amzn   | 2.1 kb     00:00      java   | 9.9 kb     00:00 ...      http://hg.openjdk.java.net/jdk7u/jdk7u/repodata/repomd.xml: [errno -1]  error   importing repomd.xml java: damaged repomd.xml file      trying other mirror.      error: cannot retrieve repository metadata (repomd.xml) repository: java.      please verify path , try again

can guide me on how resolve this?

i'm confused. title , contents not match.

yum - tool used on rpm-based distros. ubuntu uses apt-get, aptitude, synaptic or software center instead.

apt-get issue ruby - please post entire command , output together? can't see java has installing ruby. btw, if ruby programmer, me, should use rvm https://rvm.io/ install , manage ruby, not ubuntu version.
