你不应该以 root 身份运行 gpg。因此请尝试不使用 sudo 来运行 gpg。
gpg --keyserver pgpkeys.mit.edu --recv-key EEA14886
gpg: requesting key EEA14886 from hkp server pgpkeys.mit.edu
gpg: key EEA14886: public key "Launchpad VLC" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)
将密钥添加到 apt-key：
gpg -a --export EEA14886 | sudo apt-key add -
[sudo] password for arun:
OK
验证密钥：
apt-key list
