    Default sudden - 'google-chrome' is signed with an unknown key - problem

    i have had google chrome installed for 9 months, have not changed any repos recently. Repo url is
    Code:
    http://dl.google.com/linux/chrome/rpm/stable/x86_64
    On my last dup i suddenly get the message:
    Code:
    file 'repomd.xml' from repository 'google-chrome' is signed with an unknown key '1397BC53640DB551'. Continue?
    thinking the key might have changed i went to http://www.google.com/linuxrepositories/ and executed

    Code:
    wget https://dl.google.com/linux/linux_signing_key.pub
    sudo rpm --import linux_signing_key.pub
    but the problem persists, can anyone shed light on the issue?

    same here. (re)loaded the public signing key like you did. still unknown key.
    downloaded the rpm from Google (got version 60.x, had version 59.x) and forced (re)install with zypper. re-install from rpm file did not add google-chrome repository. manually (re)added repo, still unknown key.
    checked key ID with web search and it appears to be fully legitimate and in existence for years.
    re-ran zypper refresh, shrugged, and answered "yes" to the question "Continue?".

    It's a flaw, been there for ages. See here: https://forums.opensuse.org/content....-Google-Chrome

    I don't know why they don't fix it, but they don't.

    the post you link appears to carry no information regards the current issue? The link regards installation and further comments suggest adding the key to prevent security warnings. In my case I had a working system with key, that suddenly started giving warnings and adding the key again does not help. (or please explain if i havnt understood).

    In my experience I am given an option during the install to "ignore" the key error and that's the end of it.

    Even so I just now uninstalled Chrome and reinstalled it via a google download just to see if I can get your issue and dig deeper. But sad to say: I can't get the error. So I'm sorry to say that I can't help this time.

    Yup, that's my experience too. Ignore once, message gone.

    If this is the long-standing key issue (not something new),
    The key is associated with a signed library (subcomponent) of Chrome.
    For various internal legal reasons, the key is required but for unknown reasons (maybe some more legal?) the "secret" isn't embedded in the main app.

    Ignoring and continueing is probably the easiest solution.
    But, if you want to fix the problem so it doesn't appear, I do remember there is a thread somewhere in this Forum's archives where someone posted the key and how to install.

    i have not chosen the ignore option since i dont really understand what is going on (and dont want to get hacked). The issue has also come up on mailing list so ill wait and go with the ignore/continue if all else fails.

    well google compiled and signed that package but they didn't include the public key in their own repository it's a google issue but
    a quick google search reveals this
    https://www.google.com/linuxrepositories/
    according to that page you can import the google key using rpm command (you can use copy/paste)
    Code:
    sudo rpm --import https://dl.google.com/linux/linux_signing_key.pub
    after importing the public key that warning should be gone
    personally I think Chromium is a better choice then Chrome for security reasons but I don't use any of them

    I didn't read your first post entiraly
    apparently you do have google's key but the error persists
    well that's a google bug and you're unsure of the validity of the rpm package (it was downloaded via https from a trusted source) you're thinking it might be a mim attack
    you have three choices report it to google or ignore it or use chromium as it's build and signed by opensuse team there's nothing they can do about 3rd party propitiatory code
