I was updating my ubuntu 12.04 and got few issues. I think something is broken that has to be fixed. Kindly help me to fix the issue when i run update command. I am receiving below errors.
W: There is no public key available for the following key IDs:
1397BC53640DB551
W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)
W: Failed to fetch http://in.archive.ubuntu.com/ubuntu/dists/precise/restricted/source/Sources Hash Sum mismatch
E: Some index files failed to download. They have been ignored, or old ones used instead.
sudo apt-get update` Running this did the trick. Got it resolved. Thx @Liso for the Link.
