执行sudo apt install python3-pip命令时我得到
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package python3-pip is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'python3-pip' has no installation candidate
并且在sources.list中添加Universe存储库后仍然会出现相同的错误。
如何为Python 3.7安装pip？
