gpg：[不知道]：无效数据包（ctb=2d）

gpg：[不知道]：无效数据包（ctb=2d）

尝试修复 Ubuntu Trusty 上我的密钥问题： 

$ apt-key list >/dev/null
gpg: [don't know]: invalid packet (ctb=2d)
gpg: keydb_search_next failed: invalid packet

因此，我已将我的密钥从 PPA 存储库备份到/etc/apt/trusted.gpg.d.BACKUP/：

$ sudo mv /etc/apt/trusted.gpg.d /etc/apt/trusted.gpg.d.BACKUP
$ apt-key list | grep gpg$
/etc/apt/trusted.gpg

然后我将密钥导回 GPG：

$ sudo mkdir /etc/apt/trusted.gpg.d/
$ for file in $(\ls /etc/apt/trusted.gpg.d.BACKUP/ | grep gpg$) 
> do
>   sudo gpg --no-default-keyring --keyring /etc/apt/trusted.gpg.d/$file --import /etc/apt/trusted.gpg.d.BACKUP/$file
> done
gpg: keyring `/etc/apt/trusted.gpg.d/andykimpe-gparted.gpg' created
gpg: key 274A7DA0: public key "Launchpad PPA for andykimpe" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)
...
gpg: keyring `/etc/apt/trusted.gpg.d/openlp-core-release.gpg' created
gpg: key DF629112: public key "Launchpad Development Packages" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)
$

当我检查时，我仍然有相同的情况：

$ apt-key list | grep gpg$
/etc/apt/trusted.gpg

就像什么都没有导入一样。

你能帮我吗 ？

这是一个权限问题：

E: Some index files failed to download. They have been ignored, or old ones used instead.

然后我用命令循环遍历丢失的键sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys $key，现在问题终于解决了。
