0: File Error. Check permissions for /etc/tedge/mosquitto-conf/tedge-mosquitto.conf about thin-edge.io HOT 7 CLOSED

Hi Artur, can you change the owner of the directory mosquitto-conf to tedge:tedge? CLI tedge connect can't write a file in a directory owned by root.
Namely, run sudo chown tedge:tedge /etc/tedge/mosquitto-conf.

Hi,
that wasn't the problem. I fixed it for me, but I think there should be a general solution.

I tried almost erverything. I also changed the ownership of the directories to default:

$ chown -R tedge:tedge /etc/tedge
$ chown -R mosquitto:mosquitto /etc/tedge/device-certs

But at least I had do set the TMPDIR to the same filesystem than /etc/tedge.
My /tmp is mounted as tmpfs but /etc is mounted as ubifs.
The following line was the final successful trial.

$ mkdir /etc/tedge/tmp
$ chwon tedge:tedge /etc/tedge/tmp
$ TMPDIR=/etc/tedge/tmp tedge connect c8y

The problem seems to be the rename() which is called in persist_tempfile().

Indeed your root cause analysis is correct. The configuration files are created as temporary files then renamed. That cannot be done across file-systems.

=> One needs to create the temporary file along the target file in the same directory.

Yes, that's what I've done with TMPDIR. But that seems to be not professional.

I might have been confusing. tedge connect will be fixed asap.

from thin-edge.io.

A fix has been merged. Can you, please, double check that the connect command is now working as expected on your device.

from thin-edge.io.

The latest version works fine, thank you.
