我拉取 UBUNTU docker 镜像，运行下载的 ubuntu 镜像，然后运行以下命令
dpkg -s libksba8来检查 docker ubuntu 系统内 libksba8 的当前版本。
当我运行上述命令时，输出如下所示
dpkg-query: package 'libksba8' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files.
因此，我从源存档文件中下载 libksba8 库，然后像下面这样手动安装它
- 下载文件
wget https://www.gnupg.org/ftp/gcrypt/libksba/libksba-1.6.3.tar.bz2 - 提取下载的文件
tar xjf libksba-1.6.3.tar.bz2 - 进入解压的文件夹
cd libksba-1.6.3 - 配置包
./configure - 构建包
make - 安装库
make install
安装后，我再次检查 libksba8 版本，然后得到下面这样的信息，但我想问的是，我安装了版本 libksba-1.6.3，为什么下面的命令显示版本 1.6.0-2ubuntu0.2。
