Aleksander: I have installed modem-manager 0.4 on my 11.10 system and it works ok - a debug log is attached (it contains the sequence connect/disconnect/connect)
It was quite painless for me to install the older release, so this might be a suitable interim solution for some other people who are having this problem. To install the version from Natty you need to: Step 1: Fetch the old .deb file. You can get this from: http://packages.ubuntu.com/natty/modemmanager In the section "Download modemmanager" click on either amd64 or i386 as appropriate for your machine and save the file somewhere. I'm using 64-bit so the file I retrieved is called: modemmanager_0.4+git.20110124t203624.00b6cce-2ubuntu1_amd64.deb Step 2: Remove the current (broken) version of modemmanager from your machine. sudo dpkg --purge modemmanager Step 3: Install the older version that you downloaded in Step 1. sudo dpkg -i modemmanager_0.4+git.20110124t203624.00b6cce-2ubuntu1_amd64.deb Step 4: (not 100% sure this is needed but won't hurt) Bounce the NetworkManager sudo stop network-manager sudo start network-manager The modem should now work as it did in 11.04. You might want to perform an additional step to prevent the update manager from reinstalling the broken version: Optional Step 5: Start the Synaptic Package Manager Find modemmanager in the packages list. It should look something like: S | | Package | Installed Version | Latest Version | Description ! modemmanager | 0.4+git.20110124t203624.00b6cce-2ubuntu1| 0.5-1ubuntu1 | D-Bus service for managing modems Click on the modemmanager package, then from the menu select Package -> Lock Version Obviously at some future time when this bug is fixed you will want to unlock this version by again selecting Package -> Lock Version ** Attachment added: "Natty modem-manager on Oneiric" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/868034/+attachment/2662771/+files/modem-manager-04-on-1110.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/868034 Title: Huawei E220 can't connect on Ubuntu 11.10 Status in ModemManager (with NetworkManager support): Unknown Status in “modemmanager” package in Ubuntu: Confirmed Status in “network-manager” package in Ubuntu: In Progress Status in “modemmanager” package in Debian: New Status in “modemmanager” package in Fedora: Unknown Bug description: I'm using Ubuntu in my HP Pavilion dv6745tx laptop.
