symbol lookup error: undefined symbol: _ZN15BluetoothServer14runningChangedERKb about nymea-networkmanager HOT 6 CLOSED

Hello! Could you sent me please the output of
apt policy nymea-networkmanager
and
apt policy libnymea-networkmanager

undefined symbol means a function is not available in the library, so maybe this is a library daemon mismach.

from nymea-networkmanager.

Indeed, apt is confused by the version number of libnymea-networkmanager. For the moment, I'll force nymea-networkmanager to 0.3.2 which worked fine for my project.

$ apt policy nymea-networkmanager 
nymea-networkmanager:
  Installed: 0.5.1+202001231339~stretch1

As you already noticed, there is a general stretch/main repository working on all armhf (which can be removed on the Raspberry Pi) and a stretch/raspbian section which is a special compiled repository for the Raspberry Pi allowing you to install this on Raspberry Pi 1, ZeroW, 2, 3 and 4.

Your /etc/apt/sources.list.d/nymea.list should look like this:

deb http://repository.nymea.io stretch raspbian

Please not if you switch in the future to debian buster, the section is gonna called deb http://repository.nymea.io buster rpi

Glad we figured it out :)

from nymea-networkmanager.

Oh, I just noticed that the stretch raspbian section is outdated and you added the stretch repository on the debian buster system. So you soulld change your nymea.list file to:

deb http://repository.nymea.io buster rpi

Sorry for the confusion, we do not build rpi packages for stretch any more.
After changing the repository I would recommend to remove the nymea-networkmanaher and libnymea-networkmanaher package and re-install from the buster rpi section.

Thanks. I do hope for a lite build sometime without dependencies on GUI libraries.

Hmm, what GUI libraries are you referring to?
