Hello, After some further testing, it seems that this is caused by installing NetworkManager via apt.
I run these commands to build and install: > wget > https://www.freedesktop.org/software/ModemManager/ModemManager-1.16.6.tar.xz > tar -Jxvf ModemManager-1.16.6.tar.xz > cd ModemManager-1.16.6 > apt-get install -y build-essential pkg-config libglib2.0-dev libgudev-1.0-dev > libmbim-glib-dev libqmi-glib-dev > ./configure --prefix=/usr --sysconfdir=/etc > --libdir=/usr/lib/x86_64-linux-gnu --with-qmi --with-mbim > --with-suspend-resume=systemd > make > make install After that I run this to install NetworkManager without ModemManager: > ➜ ~ apt install network-manager modemmanager- > Reading package lists...

[Y/n] It seems that after that, ModemManager breaks, because the NetworkManager install is doing something to break it. I am not sure on how to move forward, should I build NetworkManager from scratch too? or should I add some other flag to ModemManager?
