Trying to investigate https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/1949621 I made a few local backports of modemmanager / libmm / libqmi packages from next 22.04 (but the source was still too old to handle the modem), and when I reverted to latest impish version, it seems the bug disappeared? I can now successfully: - use mmcli, as a standard user, like before - use modem-manager-gui, as a standard user, like before - see modem from GNOME Control Center and interact with it, as a standard user, like before. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1946481 Title: GNOME Control Center cannot connect to ModemManager with "org.freedesktop.DBus.Error.AccessDenied" Status in modemmanager package in Ubuntu: New Bug description: Upgraded my laptop (ThinkPad P14s Gen2) from 21.04 to 21.10, trying to get access to Modem Manager fails with: > error: couldn't create manager: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied This was working on 21.04.

Running GNOME Control Center as root (not a good idea, I know), clearly gets the ModemManager connection to work. ** Attachment added: "GNOME Control Center (root)" https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/1946481/+attachment/5534919/+files/Capture%20d%E2%80%99%C3%A9cran%20de%202021-10-21%2015-19-24.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1946481 Title: GNOME Control Center cannot connect to ModemManager with "org.freedesktop.DBus.Error.AccessDenied" Status in modemmanager package in Ubuntu: New Bug description: Upgraded my laptop (ThinkPad P14s Gen2) from 21.04 to 21.10, trying to get access to Modem Manager fails with: > error: couldn't create manager: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied This was working on 21.04.

[Desktop-packages] [Bug 1946481] Re: GNOME Control Center cannot connect to ModemManager with "org.freedesktop.DBus.Error.AccessDenied"
According to the policies in place for ModemManager in /etc/dbus-1/system.d/org.freedesktop.ModemManager1.conf it looks like only root can really do something. Assuming this is right, then I'm wondering why GNOME Control Center tries to directly access ModemManager instead of going via NetworkManager ? At least that is what I am wondering from the error in message #1 from `(uid=1000 pid=49211 comm="gnome-control-center " label="unconfined")` ** Summary changed: - NetworkManager cannot connect to ModemManager with "org.freedesktop.DBus.Error.AccessDenied" + GNOME Control Center cannot connect to ModemManager with "org.freedesktop.DBus.Error.AccessDenied" ** Bug watch added: gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues #402 https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/402 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1946481 Title: GNOME Control Center cannot connect to ModemManager with "org.freedesktop.DBus.Error.AccessDenied" Status in modemmanager package in Ubuntu: New Bug description: Upgraded my laptop (ThinkPad P14s Gen2) from 21.04 to 21.10, trying to get access to Modem Manager fails with: > error: couldn't create manager: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied This was working on 21.04.
