Device Manageability feature

[Mauricio]

Hi everyone,

I am automating the process of installing and configuring the device management feature.

I have founded some errors:

1) The update step, can sometimes fail.

So, my workaround is replace the lines with this one:

apt-get update >&/dev/null || echo 'no-possible-update'

in the install-tc.sh file.

2) On Ubuntu 20.04, I having an issue related to trtl:

Now, I am having a problem with trtl package:

Do you know why I get this error?

Hi Mauri,

Thanks for reaching out. The Edge Insights for Industrial software package and the Device Manageability list Ubuntu 18.04 as a pre-requisite. Could you try this process on a Ubuntu 18.04 system and let me know if you continue to have this issue?

Regards,

Jesus

Hi Jesus,

I have had the same error on Ubuntu 18.04.

My workaround was:

sudo apt remove --purge apparmor 
reboot
sudo apt install apparmor

but I am not sure that was the solution.

I have been problems with the services:

apparmor.service

trtl

configuration.service

mqtt.service

In this moment I do not have this errors.

If I install turtle creek every time I use it, I do not have this errors.

Best regards,

Mauri

Hi Mauri,

Edge Insights for Industrial version 2.6.1 is now available, could you check if you run into the same error on this release?
