That is really unfortunate, if someone can help try to debug this issue further, it would be great. According to the comment I added in that issue it could be related to how the inhibition process leaves a port around open in the old modem object. > I have been trying to get a modemanager 1.16 .deb file to install on my > Ubuntu 20.04 system, but was not able to find one online, so I decided to > compile from source. > > I have ran the following, as per this build guide: > https://modemmanager.org/docs/modemmanager/building/building-autotools/ > > $ 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 > $ ./configure --prefix=/usr --sysconfdir=/etc > --libdir=/usr/lib/x86_64-linux-gnu --with-qmi --with-mbim > --with-suspend-resume=systemd > $ make And "sudo make install" I hope? > > > but systemd fails to load the service, and if I try manually I get this: > > $ /usr/sbin/ModemManager > /usr/sbin/ModemManager: symbol lookup error: /usr/sbin/ModemManager: > undefined symbol: mm_location_3gpp_set_mobile_country_code This looks like the MM program is trying to use an older library in the system, not really a problem in the MM build I'm afraid. > > > I have also tried removing these flags: > > --prefix=/usr --sysconfdir=/etc --libdir=/usr/lib/x86_64-linux-gnu > If you tried to remove those flags it could very well be that you installed under /usr/local also and then there's a mix of libraries and binaries around.
