Python 3 installation from dietpi-software fails

Troubleshooting
1

Hi,

I’m trying to install Bazarr (for Radarr subtitles) and the installation fails when installing Python3, which is required for Bazarr. When I try to install it, I get this error :

The command that appears to fail is the following :

curl -ILfvm 10 https://bootstrap.pypa.io/pip/get-pip.py

I tried to execute it separately in a subshell, I get the same error.
I also tried to install Python 3 separately, from dietpi-software. I get the same error too. But it proves that the error is only with Python 3 and not Bazarr.

Does someone have an idea of what is happening ?
Thanks in advance for any answer, have a great day everyone !

Hi,

mayby an temp issues with the external server https://bootstrap.pypa.io hosting the python install script

curl: (22) The requested URL returned error: 503 Service Unavailable

I did a quick test and it was working fine. Maybe you can try again. Not sure if applicable, but probably you can check as well DNS/AdBlocker if installed.

You were right, it was apparently a temporary issue. I don’t think it was on my end as I’m not using any adblocker, I’m using Cloudflare DNS but in normal mode (no safe or family mode) so it should let everything pass. Anyway, it worked now. Thanks for your answer ! Have a good day and thanks for everything you’re doing for this community
