Omega 2+ not starting after package updates

Jonathan Jefferies

Hi. I hadn't used my Omega 2+ in a while, so ran opkg update yesterday and saw that there were a load of packages that need upgrading. There doesn't seem to be a way to upgrade everything, so I started upgrading a few of them individually. After I did opkg upgrade opkg opkg seemed to stop working.

I did a reboot to see if that would help, but the Omega won't start up properly now. The orange light comes on for about 8 seconds, then flashes for 3 or 4 seconds, then the light goes out. The WiFi access point never becomes available, so I can't connect to it.

I've tried to do a factory reset several times, but holding down the reset button, but nothing seems to happen.

Has anyone got any ideas? Thanks.

If you have a mini dock or expansion dock, try and connect to the console and see if you can get any hints as to what is happening in the boot stage.

From your description of the start up, it fits the profile of not getting enough A's to start up, so if you're not powering the device from a dock, make sure it's getting enough 'juice' to boot. If you are using a dock, check the amperage of your power supply, often you need more than 500mA.

I realise that doesn't correlate to the opkg upgrade, but in order to investigate that, the device has to start up at least.

Hey. Thanks. I managed to connect via serial. This is the last page of output:

I remember seeing the Error relocating /lib/libubus.so: uloop_cancelling: symbol not found or something similar while I was doing some opkg upgrade ..., so presumably it's related to that.

Jonathan Jefferies

OK. I've pressed F + Enter to enter Failsafe mode and it's given me the option to do a factory reset...

Jonathan Jefferies

I've done the factory reset, and now the access point comes up and I can connect to it. When I try to run wifisetup I keep getting the same Error relocating /lib/libubus.so: uloop_cancelling: symbol not found over and over again.

Potentially the same issue as in this post: https://community.onion.io/post/15469

@Jonathan-Jefferies
Possibly. If you can identify the correct libubus package, you could try downloading it from the repo (there are a few revisions there) and then installing it manually.
But honestly, since you don't seem to mind resetting your device, I'd suggest you just reflash it from USB using the stable b160 firmware image and start from scratch.

Quite why a factory reset doesn't do what it says on the tin is a bit disconcerting though. What's so special about libubus that when it breaks, it survives a factory reset? More research required.

Jonathan Jefferies

I assumed a factory reset was my only option. Hopefully all the code I had on there is in repositories anyway, so I'm hoping it won't matter too much.

It does seem very strange that the problem with that package still exists after the factory reset. I'll try and get some more information.

Jonathan Jefferies

Ok, I must've not done the reset correctly. It's worked now.

Thanks for your help
