I don't understand why this issue could be survive. It display this error message all the time
Fetched 32.8 MB in 1min 16s (430 kB/s) W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/trusty-security/main/binary-amd64/Packages Hash Sum mismatch W: Failed to fetch http://security.ubuntu.com/ubuntu/dists/trusty-security/universe/binary-i386/Packages Hash Sum mismatch E: Some index files failed to download. They have been ignored, or old ones used instead.
I was tried to using these commands (which found in this question)
sudo apt-get clean sudo rm -vf /var/lib/apt/lists/* sudo rm -vf /var/lib/apt/lists/partial/* sudo apt-get update
No luck for me. That dump message show up again. Always failed with
security.ubuntu.com. My internet connection is OK, I'm able to ping to
security.ubuntu.com without any trouble.
So, the question here is why? And anyone out there can help me out of this? I'm going to crazy!
