Thread: Raspi 3 TW - Update went wrong, grub2 console

  1. #1

    Question Raspi 3 TW - Update went wrong, grub2 console

    Hi!

    Something went wrong with the update of an older TW (XFCE Desktop) install on a Rapsi 3, now the boot shows "Welcome to grub" and then swiches to a GRUB console, no idea what to do there.

    Had a look at the first partition of the SD-card (BOOT), compared to another Raspi 3 with TW, had no /EFI/BOOT/grub.cfg file. Copied over from other Rapsi, replacing the UUID from the actual card, didn't change anything.

    Any ideas (as there is no way to boot the raspi from CD, USB etc.) how to get this going again?
    Kind regards

    ...had a look at /boot/ on the ROOT partition, no kernels, no initramfs, something went really wrong here. Any way to fix that?
    Kind regards

    Hi
    FYI, RPI installs, aren't installs but created from a prebuilt image onto a MicroSD or USB device... there are only a few questions to answer for setup, but nothing like an iso image install...

    And, TW images are deprecated and become unusable fast.
    More than likely a brand new image will have to be downloaded.

    @tsu

    What do you mean by "deprecated"? Are TW on raspi installs not meant to be updated? Just install and never update? **shock**

    It was a samba server, miight anybody guide me trough how to save my samba config, passwords etc and "transplant" to a fresh install (TW or whatever...)

    Many thanks in advance!
    Kind regards

    No, he means if you install an ISO image, let's say 6 months old, you have to most likely download gigabytes of data because everything has gone up a version or two. Thus, the old ISO is out of date and "deprecated" (meaning a new version is available)

    Personally, I'd just grab the latest TW ISO and install it on top of your old version - it should "upgrade" and save your configuration files.

    Hi miuku!

    The TW that failed to update was running for more than a year, last update some 3-4 weeks ago (8GB card btw..., so problems ahead). Tried to update anyway, had 900 updates, after reboot no kernels etc.

    By new install from TW .iso you mean the procedure described here:

    https://en.opensuse.org/HCL:Raspberr....28upstream.29

    with an SD-card and an US-stick?

    Did you ever do this tuff? Sounds experimental... I'm not in experimental mode, just wanted my samba share up and running soon :-)
    Kind regards

    Start with checking from where this grub was loaded. Use "echo $cmdpath" (or simply "set" command); $cmdpath on EFI should be set to full directory name from which grub was loaded

    How exactly you "had a look"? Please paste exact commands used to get access to and display content of /boot/ with their output.
