如果我想升级 pip，也会发生这种情况：

python3 -m pip install --upgrade pip

我将 Ubuntu 16.04 升级到 20.04。我确定我已经删除了 Python 2。

sudo update-alternatives --config python3
update-alternatives: error: no alternatives for python3

我使用sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10没有错误

update-alternatives: using /usr/bin/python3 to provide /usr/bin/python (python) in auto mode

我希望你能帮助我。提前致谢。
