我在 Ubutun 20.04 中提到了 Spyder。它说“Spyder 4.1.3 可用!”。我安装的是4.1.2版本。在命令行上我收到一条消息:

spyder is already the newest version (3.3.6+dfsg1-4build1).
The following packages were automatically installed and are no longer required:
libgnutls-openssl27 libvpx5
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
那么 4.1.2 比 4.1.3 版本更新,这是怎么回事?或者这是一个错误?
答案1
我假设
a) Spyder 在自己的服务器上测试新版本
b) Ubuntu 存储库尚未提供版本 4.1.3,因此 4.1.2 是它所知道的最新版本
因此,该程序将提供新版本,但您apt
将无法安装它,因为它缺少新版本的源。
