Hello, I’m new to Galaxy and I’m currently trying to get Galaxy (version 20.01) onto a Linux machine (os: Linux-3.10.0-1062.1.2.el7.x86\_64). I followed the instructions on [https://galaxyproject.org/admin/get-galaxy/](https://galaxyproject.org/admin/get-galaxy/).

I began by cloning a new galaxy repository:  
$ git clone -b release\_20.01 [https://github.com/galaxyproject/galaxy.git](https://github.com/galaxyproject/galaxy.git)

Then I started it up:  
$ sh run.sh

It all seems to run smoothly until I get to this section:  
\*\*\* Operational MODE: threaded \*\*\*  
added lib/ to pythonpath.

We’ve installed pysqlite3 and the sqlite-devel linux package but this doesn’t seem to resolve the issue.

Any help would be greatly appreciated. Thank you!

Hi @G_Lab

It appears that the _system python_ is being used instead of _conda python_. That can lead to odd problems. And not just during the initial start-up phase, but later within the application itself (core functionality issues, tool dependency problems).

Try creating a virtualenv `.venv` in your `../galaxy/` directory and allowing Galaxy to manage dependencies. Shut down Galaxy first, add the `.venv`, then rerun `sh run.sh`. If that doesn’t work, try again with a fresh checkout.

Simple instructions are here, for `OSX`, but it describes the general process that you can adapt it for your OS: [Example step-by-step for a basic local Galaxy install with an admin account created](https://help.galaxyproject.org/t/example-step-by-step-for-a-basic-local-galaxy-install-with-an-admin-account-created/1451)

More about dependency resolvers is covered in the Galaxy Admin docs here:

- [https://docs.galaxyproject.org/en/master/admin/dependency\_resolvers.html](https://docs.galaxyproject.org/en/master/admin/dependency_resolvers.html)
- [https://docs.galaxyproject.org/en/master/admin/conda\_faq.html](https://docs.galaxyproject.org/en/master/admin/conda_faq.html)

Let us know how this goes, and we can help more if needed.

Thanks!
