[haelix888]

any way I can help debug this?

[polmr]

Hi @haelix888 ,
is that a result of an attempt to set a sync?
The above log is missing the query to g.api.mega.co.nz, there we can examine if there is something wrong with the query. Note. g.api.mega.co.nz is not accepting the provided inputs: wrong arguments apparently.

Btw, that snipped of log shows that you are using a proxy. The returned response is well formed, so that is not likely to be the case. But just in case, you might want to try again without it if feasible.

[haelix888]

Pasting a larger extract of the log. No proxy this time. I'm using 2-factor auth. All start from clean (empty cache and configuration folder). The exact same thing works with megacmd 1.4.x.

I believe everything looks good until the ADD_SYNC request.

[haelix888]

@polmr thanks and lemme know how to help.

[polmr]

Hi @haelix888 , thanks for posting that out.
What is your operating system?
There is some issue when trying to gather an identifier for your computer.
Ideally, there should be some /etc/machine-id or /var/lib/dbus/machine-id file in your computer (assuming linux), but it does not seem to be the case for you.
A nasty way to circumvent this would be to ensure one of those files contains something useful:

sudo echo "somerandomidentifiergoeshere1234" > /etc/machine-id

Please, let us know any particularities on your operating system, so that we can try to find a general fix, just in case, other users are affected

[haelix888]

That was it, thanks.

I was running megacmd inside a recent linux Docker container where /etc/machine-id was missing.

A more correct way to generate that file is:

dbus-uuidgen > /etc/machine-id

After which the file contents is something like

$ cat /etc/machine-id 
ab4fcf0cdcefa7ad2dbb32186229d14a

A normal Linux machine (at least those with a desktop environment) will have that file, so I'm not sure if you need to do anything. Much appreciate the hint.

[polmr]

Thanks for reporting back @haelix888 !

[egeres]

I'm using MEGAcmd in termux and I don't have permission to write /etc/machine-id, what could be an alternative to setting the ID of the machine...?
