I just tried to update one my Kali Virtual Machine and received the following error:
root@kali:~# root@kali:~# apt-get update Get:1 http://kali.mirror.garr.it/mirrors/kali kali-rolling InRelease [30.5 kB] Err:1 http://kali.mirror.garr.it/mirrors/kali kali-rolling InRelease The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <devel@kali.org> Reading package lists... Done W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://kali.mirror.garr.it/mirrors/kali kali-rolling InRelease: The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <devel@kali.org> W: Failed to fetch http://http.kali.org/kali/dists/kali-rolling/InRelease The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <devel@kali.org> W: Some index files failed to download. They have been ignored, or old ones used instead. root@kali:~
It seems like the APT GPG Key expired. Searched around and the found that the following solution worked for most people:
root@kali:~# apt-key adv --keyserver hkp://keys.gnupg.net --recv-keys 7D8D0BF6 Executing: /tmp/apt-key-gpghome.Ze2Ri87qe6/gpg.1.sh --keyserver hkp://keys.gnupg.net --recv-keys 7D8D0BF6 gpg: key ED444FF07D8D0BF6: 133 signatures not checked due to missing keys gpg: key ED444FF07D8D0BF6: "Kali Linux Repository <devel@kali.org>" 135 new signatures gpg: Total number processed: 1 gpg: new signatures: 135 root@kali:~#
After that, you simply try to run apt-get update and it should just work as normal.
Apparently the above solution didn’t work for few, here’s an alternative solution:
root@kali:~# wget https://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2018.1_all.deb root@kali:~# apt install ./kali-archive-keyring_2018.1_all.deb
However, you need to ensure that your Kali Linux Repositories are correct, mine were as follows:
If you want a guide on how to fix you Kali Linux Official Repositories, follow this guide. Follow the Kali Rolling section.

tried to fix but I got gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation after I put in apt-key adv –keyserver hkp://keys.gnupg.net –recv-keys 7D8D0BF6
i got the same thing… are you also trying to run apt within wsl? I was looking at something the other day that was saying the issue might be related to having the right permissions within windows for your distro and/or an issue related to your PATH will get post my answer if i figure it out.
