How to fix Turris Omnia "Signature check failed"

So, I got a new Turris Omnia and flashed the latest Turris OS 7.0.0 using the medkit (USB flash), and opkg didn’t work.

Whenever I ran “opkg update” I got the error: Signature check failed. Remove wrong signature file.

As it turns out, the latest medkit I used sets the wrong repo URLs. The repo of the OS is set to HBS but the URLs point to HBL.

To fix this, SSH into your router and run the following command:

switch-branch hbs

This will configure everything correctly.

If you want to play it safe you can run switch-branch without any arguments to see what current branch you’re on.

Note: User forums suggested just changing the URLs manually, but I recommend using the built-in command instead because this will reinstall everything properly to make sure you’re on the correct branch.

Enjoy!

I run this blog in my free time, consider tipping a coffee if I helped you out. (:

  hbs (snails, stable)
    The default and most stable rolling release. Suggested for unexperienced
    users and for critical infrastructure.
  hbt (turtles, testing)
    This rolling release contains next stable version. Please join this branch to
    help us test it and to get new stuff few weeks up-front.
  hbk (kittens, next-fixup)
    This rolling release tracks stable OpenWrt upstream and stable Turris
    development. It is commonly used to prepare next fixup releases (aka 1.0.x)
    or next minor or major if no more fixup version would be released. Manual
    intervention might be sometimes required to fix introduced bugs and because of
    that it is suggested to be used only by experienced users.
  hbl (lions, next-minor)
    This rolling release tracks stable OpenWrt upstream and the latest Turris
    development. It is commonly used to prepare next minor releases (aka 1.x.0)
    or next major if no more minor version would be released. Manual intervention
    might be sometimes required to fix introduced bugs and because of that it is
    suggested to be used only by experienced users.
  hbd (dragons, next-major)
    This rolling release not only tracks the latest Turris but also the latest
    OpenWrt development. It is commonly used to prepare next major release
    (aka x.0.0). It can frequently break and is suggested to be used only by
    experienced users on non-critical infrastructure.
