Debian

GPG 密鑰新密鑰但不包含使用者 ID

  • June 21, 2020

我添加了一個新來源

deb http://httpredir.debian.org/debian buster-backports main contrib

到我的樹莓派上的源列表文件。當我更新我的 sudo apt 以確認更改時,我收到此錯誤:

sudo apt update
Hit:1 http://raspbian.raspberrypi.org/raspbian buster InRelease
Get:2 http://httpredir.debian.org/debian buster-backports InRelease [46.7 kB]
Get:3 http://archive.raspberrypi.org/debian buster InRelease [32.6 kB]
Err:2 http://httpredir.debian.org/debian buster-backports InRelease
 The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 04EE7237B7D453EC NO_PUBKEY 648ACFD622F3D138

W: GPG error: http://httpredir.debian.org/debian buster-backports InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 04EE7237B7D453EC NO_PUBKEY 648ACFD622F3D138
E: The repository 'http://httpredir.debian.org/debian buster-backports InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

我得到了以下指示:

gpg --recv-keys 04EE7237B7D453EC
gpg --recv-keys 648ACFD622F3D138
gpg --export 04EE7237B7D453EC | sudo apt-key add -
gpg --export 648ACFD622F3D138 | sudo apt-key add -

但是當我執行這個命令時:

gpg --recv-keys 04EE7237B7D453EC

我收到此錯誤:

gpg: key E0B11894F66AEC98: new key but contains no user ID - skipped
gpg: Total number processed: 1
gpg:           w/o user IDs: 1

該輸出應該發生嗎?我按照說明進行操作,但仍然出現以前的錯誤,public key is not available這表明我的鑰匙有問題。

我找到了答案:

包管理器需要 PGP 密鑰來驗證來自新儲存庫的包集。您首先必須從密鑰伺服器獲取密鑰,例如 SKS 一個:

$ gpg --recv-keys --keyserver ipv4.pool.sks-keyservers.net 04EE7237B7D453EC
gpg: key E0B11894F66AEC98: public key "Debian Archive Automatic Signing Key (9/stretch) <ftpmaster@debian.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1
$ gpg --recv-keys --keyserver ipv4.pool.sks-keyservers.net 648ACFD622F3D138
gpg: key DC30D7C23CBBABEE: public key "Debian Archive Automatic Signing Key (10/buster) <ftpmaster@debian.org>" imported
gpg: Total number processed: 1
gpg:               imported: 1

然後將它們導入您的本地 APT 密鑰庫:

$ gpg --export 04EE7237B7D453EC | sudo apt-key add -
OK
$ gpg --export 648ACFD622F3D138 | sudo apt-key add -
OK

然後你的 apt update 應該可以工作了。
