Hello, I have frequent errors when I do apt-get update: W: Failed to fetch http://http.debian.net/debian/dists/jessie-backports/main/source/Sources Hash Sum mismatch
W: Failed to fetch http://http.debian.net/debian/dists/jessie-backports/main/i18n/Translation-en Hash Sum mismatch W: Failed to fetch http://http.debian.net/debian/dists/jessie-backports/main/binary-amd64/PackagesIndex Hash Sum mismatch Sometimes it works, sometimes it doesn't. The problem appeared on all my servers running Debian 8 (hosted on Google Cloud Platform) the last couple of days. What's wrong and what would you recommend?
