nrfconnect-2.5.0-x86_64.AppImage requires more installation steps on Ubuntu 18.04 than documented

[Achim Kraus]

Using a nRF52832-DK and nrfconnect-2.0 on Win 10 everything works well.

But using that with Ubuntu 18.04 requires more installation documentation!

1. it seems, that the segger jlink software 6.20b (exactly that version) must be installed ahead.

2. even when the user is added to dialout, "Error while setting up device ....: Keine Berechtigung, cannot open /dev/ttyACM0" is reported.

  starting as su works.

crw-rw---- 1 root dialout 166, 0 Sep  2 18:51 /dev/ttyACM0

Please check, why it's required to run a su, I would prefer to run it as normal user in the dialout group.

Hi,

Small update.

I can confirm the j-Link software must be preinstalled.

For the permissions issue, see nrf-udev.

Even with that, using ubuntu 18.04 keeps reporting

"Error while setting up device 000681482097: Error: Das Gerät oder die Ressource ist belegt, cannot open /dev/ttyACM0".

I double checked, that I'm member of the dialout group, the mods for 

crw-rw---- 1 root  dialout 166,  0 Sep  6 17:53 /dev/ttyACM0

seems to be also right.Using sudo works.

So frank question:

is it tested with ubuntu 18.04, or assumed, that it must work?
