Thread: LEAP 15: Offline Upgrade USB loads but hangs on loading udev

    Default LEAP 15: Offline Upgrade USB loads but hangs on loading udev

    Fellow opensuse users,

    I have been using Opensuse since 2008 (13.1). I am trying to do an offline upgrade from 42.3 to 15.

    A bootable USB is being created using the SUSE Studio Imagewriter with the Leap 15 iso downloaded via torrent.

    The stick loads but on selecting Upgrade or Check Installation Media, the installer hangs on loading udev.

    What can I do so the installer finishes loading? I tried playing around with the non-UEFI/UEFI settings and the kernal setting set to safe but still no go.

    Any suggestions?

    Media check does not work for USB sticks only on CD/DVDs. If you have a good checksum checked iso image a copy to a USB should be good.

    Also not sure how up to date Imagewriter is. If copying from Linux just use cp or dd command for cp cp pathtoimage /dev/sdX were X is the reference to the device Note copy to device NOT a partition on the device. You can find USB deice by fdisk -l . If in Windows use a good binary copy program like https://www.osforensics.com/tools/write-usb-images.html

    I did my installs as clean installs.

    I did try an upgrade -- twice -- in a virtual machine. The upgrade worked. However, it first connected to online repos. It did not give me a choice for doing it offline. I suppose I could have removed the network card from the virtual hardware, to see what happens. But I didn't try that.
    openSUSE Leap 15.3; KDE Plasma 5.18.6;

    I am guessing you are installing UEFI.

    Highlight the Install option on the menu, type "e".

    Scroll down to the line that starts with "linux" (linux-efi?).

    Hit the END key to get to the end of that boot command line, it wraps.

    Add a space, then add "self_update" (without the quotes), then press F10 to boot the installer.

    You will need to wait a few moments as it downloads some additional files.

    See if that solves your problem.

    If not installing UEFI, then just add that to the end of the command line parameters.

    I have the exact same problem on 2 different machines, luckily I still had a 42.3 ISO so I've used that for the time being. Bit odd, though. I may wait another few months until I go to 15.

    I tried that but udev still hangs.

    SUSE Studio Imagewriter (from the repos) creates on my usb the following:

    1. 1.3 mb free space
    2. 4.0 mb /dev/sdb1 -- EFI
    3. 3.9 gb /dev/sdb2 -- ISO/bootable.

    My bios detects the usb as either UEFI/regular. I tried both settings but the usb still hangs on loading udev.

    I tried some research into udev but why would the installer be hanging there? Is it the USB/BIOS or my hardware?

    Any suggestions would be helpful. I don't want to do a live upgrade, but might consider it.

    I used the usb on a different and older but more powerful laptop and the usb loaded through the Check Installation Media option.

    So...what option(s) in BIOS would cause udev in the installer to hang? I will try turning on/off some options there and report back.

    Hi, I am trying to install via a DVD. The install hangs, last message was something to the effect 'udev=OK'.
    Then the triple green bar at the bottom of the screen appears, grows, stops growing. The CD-drive stops,
    and that is the end of the exercise. The CD has been checked and found to be OK.

    The PC is an ASUS N75SF. No problems booting 42.3.
    A memory check has been performed, no memory errors.

    Best regards,
    Jan Christian

    For USB install be sure that UEFI option iommu is turn on. or USB may stop working as soon as kernel is loaded.

    Had this not on an install but a replacement of mother board recently the default on the MB was iommu off and USB devices stopped working as soon a kernel loaded

    Yes, unfortunately. I have learned since that the "self_update" feature is *not* enabled in openSUSE, though it is there for SLES, etc.

    I am quite disappointed in that.

    ... although, I was sure it worked for me in a couple of instances, so I am still left scratching my head.
