looks like the problem was caused by a sensor failure that led to further issues resulting in the abort. There are a few more soyuz rocket flights upcoming, and with the cause identified, that might lead to crewed Soyuz launch in December, which in turn will keep ISS from running without a crew in early 2019.
They've expanded on the initial report to say that it was an assembly fault the lead to the failure and two other rockets have been disassembled and repaired.

Talk is the next flight will be in December with a Canadian aboard and will result in the current ISS crew staying aboard for an extra week or so.
