Arch Linux User Repository

In order to check a new version

$ git clone https://aur.archlinux.org/miniconda3.git
$ cd miniconda3
$ nvchecker -c .nvchecker.toml                        
[I 07-09 21:47:02.603 core:416] miniconda3: updated to 24.5.0.0

Important note: This is the way how to upgrade.

Suppose that we have this line in ~/.bashrc or ~/.zshrc or etc.

[ -f /opt/miniconda3/etc/profile.d/conda.sh ] && source /opt/miniconda3/etc/profile.d/conda.sh

1. Before to upgrade I comment this line.
2. Upgrade the package as usual.
3. Uncomment the line.

I have packaged micromamba in AUR. Try it if you are looking for a lightweight, barebones alternative to miniconda.

I have a similar problem as @joanmanel and have no CONDA_* variables in env... but it is not "/opt/miniconda3/pkgs/" but "/opt/miniconda3/lib/python3.11/site-packages/" where the conflicts lie.

I also manually activate conda, so there is no need to uncomment any lines, and conda is deactivated.

Hi @joanmanel, could you look

$ env

and look if any CONDA_FOO environment variable is activated?

Hi there. Went to update the package (through yay). I uncommented the line in bashrc as suggested. But I went a bunch of

miniconda: /opt/miniconda3/pkgs/.... exists in filesystem

I'm usually wary of using sudo with pip, and I found with a slight variation of @kearneyBack's method as below, you can run a non-sudo pip in the base conda env and get the cryptography and pyOpenSSL packages updated just fine:

$ conda activate base
(base) $ pip list | grep cryptography
cryptography            39.0.1
(base) $ pip install -U cryptography pyOpenSSL

From then on conda worked fine again.

Hi @busywhistling, yes conda 23.7.2 is available, but no available from here https://repo.continuum.io/miniconda

I tried conda activate base but got same error. Here is a way.

$ pwd
/opt/miniconda3/bin
$ ./pip list | grep pyOpenSSL
pyOpenSSL               23.0.0
$ ./pip list | grep cryptography
cryptography            39.0.1
$ sudo ./pip uninstall cryptography pyOpenSSL
$ sudo ./pip install cryptography pyOpenSSL
Successfully installed cryptography-41.0.3 pyOpenSSL-23.2.0

conda work again. thank gru

Thanks that worked

I had the same issue on an old installation. I solved it by activating the base conda env and updating with pip pyopenssl and cryptography. I hope this helps.

On a fresh Arch installation, I just installed miniconda3 with yay, and when executing conda I get the following error

(I have openssl installed and also python-pyopenssl and other packages it installs like python-cryptography)
