After we update the Ubuntu software source to a domestic source (e.g. 163s), update has the following error:

W: Failed to fetch bzip2:/var/lib/apt/lists/partial/mirrors.163.com_ubuntu_dists_trusty-security_main_source_Sources Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead.

This is due to GFW. The size of the file we obtained is not the same as that on the official source, resulting in a different MD5 value, so Hash Sum mismatch will appear. We can solve this problem by setting up agents.

There are many online solutions:

(1) I solved it in this way.

Sudo apt-get clean sudo apt-get update-fix-missing

(2) delete the contents of the / var/lib/apt/lists directory

# Delete sudo rm-fR / var/lib/apt/lists/* # create a new folder sudo mkdir / var/lib/apt/lists/partial # re-update sudo apt-get update

(3) change the source.

It seems that starting from ubuntu11.04, the source change can be operated directly in system settings, without the trouble of the command line.

Ps: in China, if it's a campus network, find a source of edu.cn. If it's not a campus network, I think it's not bad to use 163mirror.

For an easier way, we can use aliyun's software source, and I haven't had this problem since I changed it.
