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:
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:

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
