GPG不工作

Question

我正在使用Ubuntu18.04.1。

我以前从gnupg.org手动安装了GPG2.1.15(包括依赖项)。

我想安装一个ppa，在运行sudo apt-key add Release.key之后，我得到了输出：

gpg: can't connect to the agent: IPC connect call failed 

然后我大惊小怪地解决了这个问题。这场疯狂的追逐收效甚微。我在GPG2和每个依赖项的目录中使用sudo make uninstall卸载了GPG2 (和依赖项)。然后，我通过apt安装了GPG2及其依赖项。

我现在完全不能使用GPG。

当我运行gpg --clearsign时，我得到了输出

gpg: can't connect to the agent: IPC connect call failed
gpg: can't connect to the agent: IPC connect call failed
gpg: keydb_search failed: No agent running
gpg: no default secret key: No agent running
gpg: [stdin]: clear-sign failed: No agent running

当我运行gpg-agent --daemon时

gpg-agent: relocation error: gpg-agent: symbol gcry_get_config version GCRYPT_1.6
           not defined in file libgcrypt.so.20 with link time reference

当我运行gpg --version时

gpg (GnuPG) 2.2.4
libgcrypt 1.7.0

Answer 1

我手动卸载、重新安装，然后再卸载libgcrypt 1.7.0，方法是转到我从gnupg.org下载的文件目录，然后运行

sudo make uninstall
sudo make install
sudo make uninstall

然后通过apt重新安装libgcrypt，运行

sudo apt install --reinstall libgcrypt20*

然后，我转到libgpg-error 1.21目录，并对libgpg-error 1.21执行相同的操作。

sudo make uninstall
sudo make install
sudo make uninstall
sudo apt install --reinstall libgpg-error0

然后，我转到libassuan 2.4.2目录。在通过apt重新安装libassuan之前，我先手动安装，然后卸载libassuan 2.4.2。

sudo make install
sudo make uninstall
sudo apt install --reinstall libassuan0
