I had same problem, I just run this command:
curl -sS | sudo apt-key add - You can usually update all of your keys at once using:
sudo apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com
this worked for me
3Build on @PA-GW's answer, I created a Cronjob that refreshes the keys daily. Hopefully, that helps for the frequently rotating keys, like NodeJS:
17 2 * * * /usr/bin/apt-key adv --refresh-keys --keyserver keyserver.ubuntu.com > /dev/null
