The regression is due to NM setting DEVICE_IFACE to "ril_0" in version 0.9.10.0 instead of "/ril_0" as in 0.9.8.8.
There has been a change in nm-modem-ofono.c:nm_modem_ofono_new that explains this (MODEM_UID is skipping the slash in the latest version). The patch that creates nm_modem_ofono_new is "add_ofono_support.patch". It is probable better to keep the change in MODEM_UID for consistency inside NM, so I have changed the script to handle this change. See attached. ** Attachment added: "03mmsproxy" https://bugs.launchpad.net/ubuntu/+source/ubuntu-download-manager/+bug/1454625/+attachment/4397380/+files/03mmsproxy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1454625 Title: Cannot send MMS messages with combined contexts with WiFi connected To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1454625/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
