Don't know if it's the same problem, I have a MX4 running an old Ubuntu Touch version r1, with the same problem. When I download a new version and try to install it, I always get this error (see image http://imgur.com/XLxG4ql ). So I try updating it via ubuntu-device-flash
ubuntu-device-flash touch --channel=ubuntu-touch/stable/ubuntu I get this error error pushing: failed to copy '/home/dario/.cache/ubuntuimages/pool /ubuntu- b5f4cc2c8fdcda0c8c2f1112f8ea22648af9fe2306e9038147427e8306c2acb2.tar.xz' to '/cache/recovery//ubuntu- b5f4cc2c8fdcda0c8c2f1112f8ea22648af9fe2306e9038147427e8306c2acb2.tar.xz': No space left on device -- 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
