我在笔记本电脑上使用Lubuntu V.17.10。在此版本的Lubuntu上默认安装了gnupg V.2.1.15和libgcrypt V.1.7.8。 我想删除gnupg V.2.1.15和libgcrypt V.1.7.8然后安装gnupg V.2.1.0和libgcrypt V.1.6.3。 过去，我安装了gnupg V.2.1.0和libgcrypt V.1.6.3。但是当我使用multi命令时，我会给出冲突答案。
~$ gpg --version

~$libgcrypt-config --version
1.6.3
这些冲突导致我对安装gnupg V.2.1.0和libgcrypt V.1.6.3没有信心。
我希望当我使用命令gpg --version时，我会给出这些答案gpg (GnuPG) 2.1.0 libgcrypt 1.6.3
