Synapse upgrade hangs -> Error 504

Support
1

My YunoHost server

Hardware: CubieTruck (a.k.a. CubieBoard 3)
YunoHost version: 3.6.5.3
I have access to my server : Through SSH and through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : yes, there are a Blynk server and a MQTT server installed

Description of my issue

I have launched the Synapse application upgrade. It seems to hang and after a long time an error throws up (Error 504).

I tried also with the cli tools : yunohost app upgrade synapse
But it hangs also.

What could be wrong?

Thanks in advance for your help

Hello,

Do you have any log of your upgrade ?

Hello,

In general, the log file can be found in webadmin. But in this case, the webadmin always reports an error 504.
Where can I find the log file?

Well in this case it’s more nginx error. Can you try to access to your server and type this command:

systemctl status nginx

Hello Josue,

The result of the systemctl status nginx:

I tried again and before I did not pay attention but it seems the system reboots after a while.

I have run the following command: yunohost app upgrade synapse
It displays the following messages:

It is running since 8h30 am this morning and has not completed now.

Which log file can I check?

Thanks in advance

Steve

You can see all log here : /var/log/yunohost/yunohost-cli.log

Something goes wrong and now Synapse is no longer on the system :frowning:

8

Probably the upgrade failed and synapse was removed on the upgrade process.

I finally reinstall Synapse but I lost everything.
