Updates through Update Manager

Asked by Inderjit Singh

When I run the update manager for updates it is failing after some time and shows the message 'check your internet connection'. As I was sure there is no problem with the internet connection , I run the command on terminal- ' sudo apt-get update' which is showing the the following problem-

"N: Ignoring file 'getdeb.list.bck' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
W: Failed to fetch gzip:/var/lib/apt/lists/partial/in.archive.ubuntu.com_ubuntu_dists_precise-updates_universe_source_Sources Hash Sum mismatch

W: Failed to fetch gzip:/var/lib/apt/lists/partial/in.archive.ubuntu.com_ubuntu_dists_precise-updates_main_binary-amd64_Packages Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead."

What is this problem. Please sort out the same by giving me solution. Thanks.

Hi ,
please open a terminal only (no other application must run) and copy-paste from here to your terminal the below commands , one at time . One line = one command

+++++++++++++++++++++++++++++++++++++++++
sudo rm /etc/apt/sources.list.d/getdeb.list.bck
sudo rm /var/lib/apt/lists* -vf
sudo apt-get update
++++++++++++++++++++++++++++++++++++++++

See if last command returns any errors.
Thanks
