Since this morning I have this error

Err :18 http://dl.google.com/linux/chrome/deb stable Release.gpg The following signatures are not valid : KEYEXPIRED 1555048520 KEYEXPIRED 1555048520 KEYEXPIRED 1555048520 KEYEXPIRED 1555048520

when I'm running

sudo apt-get update -y

I searched some solutions but I didn't find the good one on google so ... I'm here

  • Apparently, google's signing key expired, so we just need to wait until they put out a new one. After they did just run wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add - to fix your problem. – jangxx Apr 12 at 8:29

    Did you read my comment? You have to wait until google puts out a new signing key. Until they do it, there is nothing we can do about the problem. – jangxx Apr 12 at 8:43

    most probably the same as askubuntu.com/questions/1133199/… – Gerald Schneider Apr 12 at 9:46

This is an ongoing problem that only seems to hit Google Chrome. In order to avoid seeing warnings, one can temporarily turn off the repository for GC.

  • Seeing this happen today as well. Disabling the repository may work, as Google Chrome can update itself. If it can't, it will show an icon for you to start the update. – Ismael Miguel Apr 12 at 16:56

wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

    Just wait until google updates their signing key. This is not going to help before they do. – jangxx Apr 12 at 8:44

To get rid of the problem (temporary) use --allow-unauthenticated in the apt command and wait until google fix the signing key.

You can check it from time to time by calling

curl 'https://dl.google.com/linux/linux_signing_key.pub' | gpg
