I am having problems with installation of Indigo in UBUNTU 14.04.3 LTS Desktop 64 Bit. I followed the installation instructions provided on ROS website. But following problems are occuring.
At step 1.3 when i run following in terminal:
sudo apt-key adv --keyserver hkp://pool.sks-keyservers.net --recv-key 0xB01FA116
following msg is displayed:
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.AyKV0NvoaE --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://pool.sks-keyservers.net --recv-key 0xB01FA116
gpg: requesting key B01FA116 from hkp server pool.sks-keyservers.net
?: pool.sks-keyservers.net: Host not found
gpgkeys: HTTP fetch error 7: couldn't connect: Connection timed out
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
Edit:
Since i m a beginner in Linux environment. I do not know much about the system and its requirements. It is also possible may be I have not configured the repositories properly. Bcoz following command is also not working properly.
sudo apt-get update
When i run it following message is displayed.

Could you try the following: sudo apt-key adv --keyserver p80.pool.sks-keyservers.net:80 --recv-key 0xB01FA116 and report back here?

I tried this. It also gives same message.

seems you are behind some proxy server, else try changing to main fetch server in software sources.

First: you cannot apt-get update until you've set up your keys properly. Second:
Could not resolve 'archive.ubuntu.com'
seems to point to a problem with your network configuration. Are you behind a proxy? Can you browse the internet normally? Can you ping archive.ubuntu.com successfully?
