You were right, system partition was 100% full. I was checking available space, but didn't noticed, that system has different partition. In my case, this problem is probably my fault, because I've been playing with some manually installed x-applications.
But it's weird, that this problem occured in other cases, for example Lars Kristian Wichmann Hansen stated, that he didn't do any nonstandard operations. Anyway sorry for causing troubles. I will probably do manual reflash to get clean install now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1568889 Title: Upgrade to OTA10 fails on Meizu MX4 To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1568889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
