Thread: Network unavailable after update to snapshot 20220518-1619.1

    Default Network unavailable after update to snapshot 20220518-1619.1

    After today's update, I had to rollback to the pre snapshot to get my network back. I locked NetworkManager* and kernel-firmware-* and updated successfully. If anybody has a clue which package set caused the problem, I'll remove the other lock and update again.

    Thanks,
    Gene

    Never mind, I just had to update NetworkManager with --recommends and all is well. I found the answer (missing NetworkManager-wifi) in the other thread about this issue.

    Something is wrong, even after getting NetworkManager-wifi installed. The wired Ethernet disappeared:

    Code:
    > ip link show
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    2: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
        link/ether 38:d5:7a:53:49:d7 brd ff:ff:ff:ff:ff:ff
    I don't see anything helpful using zypper se NetworkManager. Any ideas?

    No driver loaded? Ethernet hardware details?
    Code:
    /sbin/lspci -nnk | grep -iA3 net
    Firmware related?
    Code:
    dmesg | grep -i firmware
    openSUSE Leap 15.4; KDE Plasma 5

    Nothing in either command about the wired Ethernet. This is a new Dell laptop, and I've never had it connected to the wired Ethernet. I'll look in Windows to see what the hardware is. Here's the output of the commands you requested.

    Code:

    It's possible the wired connection has never been running, since that was the first time I ran the "ip link show" command on this hardware.

    *EDIT*

    Wow, I can't believe I missed this detail when I ordered this laptop. It has no wired Ethernet. This is a first for Dell laptops I've owned over the years.

    Hi
    I have a couple of spare USB -> Ethernet devices around for those types of systems

    Hi
    I've had OTB experience with the TP-Link USB to Ethernet Adapter UE305 device, the new ones UE306 should be fine.

    The SLES people split networkmanager into multiple parts to make server images smaller. Kind of like what they did to the kernel where you need kernel-default-extra and kernel-default-optional as that code was removed to make smaller servers.

    Remember that SLES customers pay for SLES and OpenSUSE get the benefits and issues caused by those that pay for support and pay for changes.

    you need networkmanager-wifi and wpa-supplicant to be added to get wifi to work as they are not a part of NW anymore in Tumbleweed.

    They should have made it installed for everyone and let servers do a zypper rm to get rid of it where it was not needed.
    OpenSUSE 15.4 with VirtualBox VM's (XP, 10, 11, Ubuntu MATE 22.04, Manjaro, 15.4, Tumbleweed)
    Pi4 with OpenSUSE 15.4
    Unix since 1974 (pdp-11, Interdata, AT&T, Tandy, Convergent, Sun, IBM, NCR, and HP)
    Linux since 1995 (Mandrake, Fedora, CentOS, OpenSUSE)
