"The schedule of manned flights to the International Space Station (ISS) will be changed after the launch of Soyuz MS-02 spacecraft was postponed due to technical malfunction, the press service of Russian space agency Roscosmos told reporters on Tuesday."
Marc's note: Originally scheduled for this Friday, the launch of the Soyuz MS-02 has been delayed until November 1 though it has also been reported by Interfax that October 12th was also considered.
There is an unspecified issue with the Soyuz MS-02 spacecraft. Plans for a November 16th launch of the follow-on Soyuz MS-03 are proceeding as planned with no issues. So is this a one-off issue? Or could the issue crop up on Soyuz MS-03?
Marc's update: According to RIA Novosti and other media reports from Russia the issue with the Soyuz MS-02, a short circuit, has been traced to a faulty part that will be replaced.

"Replacing the damaged cable is relatively straight forward, but it now has to be conducted on the vehicle fully loaded with toxic propellants and pressurized gases. Such an attempt would violate usual safety rules, but draining the spacecraft off its propellants and gases would likely be even more unprecedented and require lengthy repairs."
