Yes, I mean only extras. I have not installed stuff from devel or testing or even activated those repos. Thats why it was a surprise to me that I couldn't update using package manager.

Also It is strange that before update there was only ~35mb free in rootfs. I thought that this was to reason why I couldn't do the update so I tried to free space by reinstall python (that was suggested in some thread). Eventually I managed to get 55mb free but still it didn't allow me to update OTA. I have no idea what was filling my rootfs, now after the update amount of free space is 41.58mb. I hope that next time I can do update using package manager.
