Phone after the jailbreak to add the source always appears posix:operation time out or failed to Fetch, add any source will appear this error, although not affect the use of the source, but I have obsessive-compulsive disorder, see Card in the Scarlet letter is like to wipe it out.
Search for a while, there is no effective solution, and then carefully looked at the information found is repo666.ultrasn0w.com response timeout, that is, dev team Source (also known as the ultrasn0w source) problems
The dev Team source is then removed and updated again to solve the problem
Dev Team Source is the official source of the Ultrasn0w tool (Dev Team Source has only one ultrasn0w software), Ultrasn0w is a snow unlock tool for locking the network lock, if not with the lock machine or not, you can remove the dev team source, Can solve the above problem!
Note: Delete this source just can't download ultrasn0w software, no other impact!
In fact, you can also change the phone's DNS to 114.114.114.114 after the attempt to add.
If this is the problem after subsequent deletions, it is recommended that you delete all your own sources directly.
