If you ever see there is a big update, press n and go to the forum and check the stable updates thread and read through it.
Sometimes there are things you have to do to make the update go smooth.
In this case there was an update 11:th aug.
In your case, you should focus on reinstalling tbh (unless you feel confirtable with how the system is running now, why are you in chroot f.ex? do the update on your system)
When that is done, read that thread, take measures if needed and then run the update.
