I have also tried all thing but my solution was download old get-pip version and install.
<ol>
<li>download: <code>curl -O https://bootstrap.pypa.io/2.7/get-pip.py</code> the file <code>get-pip.py</code></li>
<li>install: <code>python get-pip.py</code> or <code>python2 get-pip.py</code></li>
<li>enjoy</li>
</ol>
This is worked on Debian systems.
<hr />
Edit: A better solution is always to install a Python version that is long supported. If at all you need to work with an older version - only then must one resort to the above workaround.

I solved it by firstly run
<code>python -m pip install --upgrade &quot;pip &lt; 19.2&quot;</code>
and then
<code>python -m pip install --upgrade &quot;pip &lt; 21.0&quot;</code>.
It seems reinstall my pip 20.3.4 and the error disappreared!
