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 Touch seeded packages, which is subscribed to system-image in Ubuntu. https://bugs.launchpad.net/bugs/1568889 Title: Upgrade to OTA10 fails on Meizu MX4 Status in Canonical System Image: Confirmed Status in system-image package in Ubuntu: Confirmed Status in ubuntu-download-manager package in Ubuntu: Invalid Bug description: On Meizu MX4 upgrade from OTA-9.1 to OTA-10 fails. Upgrade downloads normally, phone restarts and starts system upgrade and after a while it freezes with strange icon (small microchip with red sign on it) When you turn off the phone and start it again it still presents itself as OTA-9.1 and again it founds and offer upgrade. Anyway some changes from OTA-10 seems to be applied, because I can see design changes, copy function in web browser etc. It's reproducible on my phone any time I try to upgrade. If I can help with output of some log, or anything else, please let me know.
