1.15.1 on Odroid-C2 doesn't work

Hi, Just detected that Syncthing doesn’t work on my Odroid-C2 with attached USB drive. Page simply doesn’t open:

Unable to connect Firefox can’t establish a connection to the server at

Started troubleshooting and conclusion is that Syncthing 1.14.0 automatically updated to 1.15.1 causing this issue.

Restored CoreELEC from backup (contain Syncthing 1.14.0)

Unplugged LAN cable

Disabled Syncthing add-on in Kodi (device accessible via CEC)

Plugged back LAN cable

set 0 in config.xml:

< autoUpgradeIntervalH >0< /autoUpgradeIntervalH >

Enabled Syncthing add-on in Kodi

Syncthing 1.14.0 works properly.

Hard to tell without logs. Could you try v1.15.1 and upload the log generated by syncthing?

Odroid C2 only is the hardware. Which OS you are using?

Syncthing web page says: image

in ssh:


Logs files I will be able to provide later on…

Nothing is recorded in the log file:

Once I have pressed the button “Upgrade To v1.15.1” it is only showing this: image

When Odroid-C2 is restarted (manualy) no entries in the log file, web page looks like: image

Maybe is better to install the right version of Syncthing 64-bit first.

Version what is installed is the official one available in CoreELEC repository. I will stay on 1.14.0 as apparently the new one 1.15.1 doesn’t work.

Is 32-bit and work … If you try v1.15.1 as 64-bit as installation on manual way?

If it comes from a third party repository, please indicate that when asking for help - that’s very important information.

Given you are using the CoreELEC repository, i.e. their builds, the update is likely unintended. Probably changes something about their build process and somehow messed up disabling auto-upgrades. In any case, that’s a question for the support venue of CoreELEC.

As to the logs you posted: They only show how syncthing stops, nothing more. Logs of the subsequent start attempt would be interesting. If there aren’t any, you need system logs of whatever manages running Syncthing. That’s a gain a question for CoreELEC.

Yes, I have realized that as well - it’s all the matter of CoreELEC repository. For the old version 9.2.7 apparently repository contain old Syncthing version and when autoupdate is performed through Syncthing itself it is causing this critical issue. For the new version 19.1 Matrix there is available Syncthing 1.15.1 in CoreELEC respository. I have already asked the question if we can expect Syncthing update in CoreELEC 9.2.7.

Sorry for my alert :slight_smile:
