This question already has an answer here:
When I try to use
sudo apt-get update
it gives this error:
Fetched 5.530 kB in 53s (104 kB/s) W: GPG error: http://extras.ubuntu.com precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 16126D3A3E5C1192 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) E: Some index files failed to download. They have been ignored, or old ones used instead.
When I try to access to etc/apt folder, it said no such file or directory.
How can I fix this?
