an empty channel.ini file is certainly not right. You can copy the one from the other device you have. It should look something like
adb shell system-image-cli -i current build number: 25 device name: krillin channel: ubuntu-touch/stable/bq-aquaris.en last update: 2015-09-09 09:13:11 version version: 25 version ubuntu: 20150825.1 version device: 20150821-736d127 version custom: 20150821-887-33-32-vivid If you want to be sure you actually have all of r25 ota6 you could do this after restoring the channel.ini file sudo system-image-cli -b 0 This will reinstallll the entire image but not remove any data -- 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/1495207 Title: BQ E4.5 (r24): after fine update to r25 system is reported as r-1 and as "never" updated Status in Canonical System Image: New Status in system-image package in Ubuntu: New Bug description: After the vacation I have updated today (September 13, 2015) my BQ 4.5 and the one of my wife to r25. Both updates went without any problem and mine does not show any issue. The one of my wife shows in About the device window: OS number: -1 (and not r25) last updated: never version: Ubuntu 15.04-armhf (20150825-170536) What went wrong and what can I do? I'm afraid that the next update will fail completely now because it can not see the current version. Apart of this the device is working.
