+    sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring -y
+
+# Import an official nginx signing key so apt could verify the packages authenticity. Fetch the key:
+
+    curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
+        | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null

+# Verify that the downloaded file contains the proper key:
+
+    gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg \
+        | grep -q 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 || exit 1
