all packages throw 403 error

[robvoi]

I can't install any micropython package. All packages throw an error 403. The json in the pypi URL exists.
I have no idea on where to start searching. Can someone maybe point me to the right direction? Thanks!

python3 -m micropip install micropython-rosserial

results in:

I'm not sure either. My test script works:

$ micropip.py install -p ~/rats micropython-copy
Installing to: /home/adminpete/rats/

The micropip.py script is a port of the official upip.py so I attempted to install your package to an ESP8266 using upip. This failed:

>>> upip.install("micropython-rosserial")
Installing to: /lib/
Warning: micropython.org SSL certificate is not validated
Installing micropython-rosserial 0.2.8 from https://files.pythonhosted.org/packages/c5/e0/3b232b334011948b543811d3b9ed2e9ad9973ec2aa27dcb6b42156a082f3/micropython-rosserial-0.2.8.tar.gz
Error installing 'micropython-rosserial': [Errno 22] EINVAL, packages may be partially installed
>>> 

I then went on to install "mcropython-copy" and to check the outcome of both installs.

>>> upip.install("micropython-copy")
Installing to: /lib/
Installing micropython-copy 3.3.3.post2 from https://micropython.org/pi/copy/copy-3.3.3.post2.tar.gz
>>>  
/home/adminpete/Downloads> ls /pyboard/lib/
copy.py
/home/adminpete/Downloads> 

So it correctly installed copy.py but did nothing with micropython-rosserial.

This suggests that either there is a problem with the package, or there is a bug or limitation in upip. I am not knowledgeable about pypi: if you are convinced that the package is valid, it might be best to raise an issue against upip and I will port any changes the maintainers make to micropip.

Sorry I can't offer anything more authoritative.

Thanks for the swift reply and your time for testing it.
I found your script as it woks for the pi pico which doesn't have wifi. That's why I got stuck with upip and hoped to have a solution with your script.

[peterhinch]

It is possible to run official upip under the Unix build of MicroPython, but on the basis of my test this won't fix your problem. You might ask in the forum: maybe someone will have an idea of why upip can't access that repository.

However, as a straight port of upip, I will only implement changes to micropip in response to improvements in upip.

I have updated the micropip README to explain this issue.
