W: Some index files failed to download. They have been ignored, or old ones used instead.
i tried by removing proxies and everything i found on forum but nothing worked for me.
Actually i want to install headers for kernel and apt-get update is a prerequist of that.
For installing headers i also used other ways like:
#apt-get install -y linux-headers-$(uname -r)
but also given an error as
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
Can some body help me please??
