Hi Pavel,
Most likely you have an issue with GPG key.
- Next instruction will help you to generate new GPG key in the Docker. Also, you can do it on the Debian machine if you don’t have Docker.
docker run -v /Users/<USER_NAME>/share_folder/:/root/share -it ubuntu
apt-get update
apt-get install gpg
gpg --gen-key
gpg --list-keys
cd /root/share
gpg --armor --output public.gpg.key --export 315F58C16D58E682E39A816AD7
gpg --armor --output private.gpg.key --export-secret-key 315F58C16D58E682E39A816AD7
- Be sure you are using private key not public in the Nexus repository settings.
- Important thing is to copy private key with all headers, next lines. If something in the document will be changed, GPG key becomes broken.
- If nothing help, I can share with you my temporary created GPG just for testing.
Good luck!
