Getting error while updating the bench

Hi,
I am getting error while doing bench update.

vishnu@vishnu-VirtualBox:~/frappe-bench$ bench update
INFO:bench.utils:updating bench
fatal: unable to access ‘https://github.com/frappe/bench/’: Could not resolve host: github.com

I appreciate, if anyone can help me out in this context.

It just looks like github timed out but if issue persists maybe try:
cd /frappe/bech-repo/
git reset
git pull
cd /frappe/frappe-bench
bench update
