List and Remove Repository GPG Keys

This is especially useful when server GPG keys are updated.

List the repository GPG keys that are currently installed with

sudo rpm -q gpg-pubkey --qf '%{NAME}-%{VERSION}-%{RELEASE}\t%{SUMMARY}\n'

List your secret keys, and decide which one to export.

gpg --list-secret-keys --keyid-format LONG

Export the secret and public parts of the key.

gpg --export --armor  &gt; gpg-pub.asc

When added --args "nomodeset" to arm-image-installer command, booting problem was fixed.

sudo arm-image-installer \
  --image=Fedora-Server-40-1.14.aarch64.raw.xz \
  --target=rpi4 \
  --media=/dev/sda \
  --resizefs \
  --args "nomodeset"
