Mullvad app not downloading from AUR

Hi, I am trying to install the mullvad GUI app from the AUR. According to the Arch Wiki, the official client is this one.

However, when I try to install it with pamac, I get an error: “one or more PGP signatures couldn’t be verified”.

I use Manjaro mikah-rc4 (the latest one).

How to solve this? Thanks a lot.

You need to import the key into your local gpg keyring.

Indeed. The instructions are in the pinned comment on the AUR page.
