Good Day, Friends!

After a software update (that actually is a system update) the mender client sometimes reports 14 hours later. The update is successful but the mender client hangs on the reporting .

mender client 3.4.0 runtime: go1.19.3

Performing update, before reboot

How can I handle this? Is there a mender client configuration for this?

I think a similar question is, how to surpress ArtifactFailure to be triggered if the device comes up after an update and has not internet connection.
Especially bothers me this line that sometimes causing trouble.

Hi @mister_kanister,

I guess that this is two effects combining here.

the client tries to reach the server, and fails because of network not reachable or not ready
a polling cycle being in the range of 12hrs would re-trigger after that time and be successful then.

So the things I’d look at is:

why is the network connection failing? Is there maybe some kind of requirement to be up and running? If so, make sure that this is started before the Mender Client
the configurations, how do the polling cycles look like?

Greets,
Josef

Thank you for your answer!

This is how mender is configured in production. 14h gap is one of the biggest gaps. I think the polling is ok.

mender setup \
--device-type $DEVICE_TYPE \
--server-url $SERVER_URL \
--server-cert /etc/mender/server.crt \
--config /mnt/mender/mender.conf \
--data /mnt/mender \
--update-poll 120 \
--inventory-poll 120 \
--retry-poll 30

What we recently discovered is, that this behaviour occurs if the internet provider of the customer is forcing using IPv6 (e.g. Vodafone, Germany). How could this affect the mender client?

The OS is using SystemV and init scripts.
