I have a mirror server that I maintain in school.
$ uname -a Linux CSE-Cloud01 4.0.0-1-amd64 #1 SMP Debian 4.0.2-1 (2015-05-11) x86_64 GNU/Linux
$ sudo apt-get update
...... W: Failed to fetch http:// mirror.cs.nchu.edu.tw/debian/dists/jessie/main/source/Sources Hash Sum mismatch W: Failed to fetch http:// mirror.cs.nchu.edu.tw/debian/dists/jessie/main/binary-amd64/Packages Hash Sum mismatch W: Failed to fetch http:// mirror.cs.nchu.edu.tw/debian/dists/jessie/non-free/binary-amd64/Packages Hash Sum mismatch W: Failed to fetch http:// mirror.cs.nchu.edu.tw/debian/dists/jessie/main/i18n/Translation-en Hash Sum mismatch E: Some index files failed to download. They have been ignored, or old ones used instead.
In mirror itself or some of my machines, It failed in the end.(some work properly.) I had tried to do the below commands that recommended, and won't work
$ apt-get clean $ rm -rf /var/cache/apt/* $ rm -rf /var/lib/apt/lists/* $ apt-get update
I can't find other solution on the internet. Did anyone know how to solve this problem?
