Comment 1 for bug 139040

You can work around this bug by physically removing the modem from the machine before installing/updating. I suspect most if not all of the people experiencing this have "soft" or "win" modems by Lucent and some other companies. The installation hangs when "configuring wvdial" as it tries to communicate with the modem. After removing the offending hardware the installation will move past that point in a few seconds and finish in a few minutes. If you connect to the internet through your ethernet card and don't need to use any other telephony applications then removing the modem is of no consequence - just make sure to cover the slot. If you need to use the modem you can still remove it before installing, then put it back in afterwards and try to configure the software manually.
