Can't install or create environment in conda

Question

Every time I try to install a package or create an environment with conda appears, a message like this:

Collecting package metadata (repodata.json): / DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): repo.anaconda.com:443

For example:

To create an environment called `env3:

conda create -n env3 -vv

I already tried:

Uninstall and reinstall Anaconda, the version of conda is 23.7.2.
Several posts with similar issue like: this and this and this and this no one worked for me.

I'm using Ubuntu 23.04. Thanks in advance.

What exactly is wrong? The environment creation looks fine. The last one looks like not waiting long enough (Anaconda **base** is often difficult to install extra packages into). Could you show examples without the `-vv` flags first? - the DEBUG info isn't adding anything here. — merv, Aug 16 '23 at 15:00
There is no error shown there - just debugging messages being printed. The HTTP codes are normal (304: unmodified; 200: OK). Please show one complete example of: a command run, the resulting behavior, and the expected behavior. — merv, Aug 16 '23 at 16:04
The resulting behavior is that I can't install anything in conda base env or in any environment. The expected behavior is first that I can install packages and second that I can create environments without that message. I am very used to Anaconda, and those messages aren't normal, and I don't know how to fix it. In the post are the commands that I ran; I don't know if you are familiar with conda/ Anaconda and virtual envs... because I don't know which other information could be useful. — geomicrobio, Aug 16 '23 at 16:25
Did your configuration get changed to turn up the verbosity? Check `conda config --show verbosity`. There is nothing inherently wrong with any of the messages shown. Please add some direct evidence here to demonstrate that an environment isn't created (show `conda env list` before and after) or a package isn't installed (show `conda list` before and after). Please edit the post with this information. — merv, Aug 16 '23 at 16:37
Also, mixing Conda Forge packages with Anaconda **base** is not recommended and often leads to infinite solves or incompatibilities. If you want Mamba, start from a minimal **base** environment, like Mambaforge. — merv, Aug 16 '23 at 16:49
