Answer 1

Do not specify the v2 in the docker pull.

Try:

docker pull 124.70.180.84:8081/docker/jib-mvn

Assuming "docker" is the name of the repo and "jib-mvn" is the name of the image.

Answer 2

After checking https://www.passwordstore.org/

pass init "ZX2C4 Password Storage Key"

mkdir: created directory ‘/home/zx2c4/.password-store’
Password store initialized for ZX2C4 Password Storage Key.
Here, ZX2C4 Password Storage Key is the ID of my GPG key. You can use your standard GPG key or use an alternative one especially for the password store as shown above.

fix it by reinitiating the pass with gpg-id.

at the very first ,I have initiated pass with my email.
