I have installed Salmon with conda. However, I think that an old version has been installed (I get some errors). How could I update with conda? I have tried conda update salmon but nothing happened. I could not install manually that s the reason I used conda. Any solutions? Thank you!

Make sure conda-forge and bioconda are in your channels: conda install -c conda-forge -c bioconda salmon=1.3.0. I assume you're not running this on Windows, since we (Bioconda) only ship for Linux and OSX at the moment.

Hi thanks for this answer Devon Ryan as it ultimately led to the solution to my salmon update. however i am wondering why conda update salmon without salmon=1.9.0 doesnt look for the current version or update to the current version. Trying to understand bioconda better. Thanks!

Have you tried conda install salmon=1.3.0, to specifically request the latest version? Sometimes, there are strange package conflicts, and so the other thing you can try is to create a new, blank, environment, and install salmon there.

Let me tag @Devon Ryan here as well, since he may have an idea what's going on with bioconda.

PackagesNotFoundError: Do you have the bioconda channel available? You can check with:

conda config --show channels

Which should print something like:

channels:
  - conda-forge
  - bioconda
  - defaults

If you don't see bioconda there, check the installation instructions to fix it.

Also, I would suggest switching to mamba for installing packages (consider that snakemake recommends installing with mamba so it should be pretty reliable)
