unfortunately I’m not the most experienced Linux user and when I try to Pkg.build(“IJulia”). We have RHL installed on the university computers. I always get the following error msg. We have RHL installed on the university computers. Why is it showing python3.8 when I mostly use python2.7 how'd I change to the lower version as default?

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:
Specifications:
- jupyter -> python[version='>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']
Your python: python=3.8
If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

A dependency conflict in conda environment seems to cause the environment to be in a state of self-conflict and it is unable to find any useful fix.
I've tried things like conda install anaconda and conda update --all but seems nothing works, they all leads to the same error:

In this case, how to make conda saving itself? Also, why conda's conflict resolver seems to be so much weaker than apt? The later always gave several alternatives that can results in a reliable fix.
You have mix used pip and conda, which caused a dependency conflict. The simplest solution is to reinstall Anaconda to recreate the broken "base" environment.
Tips:
Use a virtual environment whenever you are working on a project. Don't install all packages in the "base" environment. The "base" is designed to work with conda the command, not recommended for your projects.
Don't mix use pip and conda in the same environment, unless you read the following reference.
Extended Reading
Create an environment from Get started with conda
Using Pip in a Conda Environment
The anaconda consists of a number of packages, so I normally start by:
$ conda create -n env_name python=3.6 anaconda
This way, it will pull in list of packages in anaconda from anaconda.org, and it should be self-consistent.
Many packages support conda install, but some only pip. The preference is to do conda install as it has a better dependency detection and resolution mechanism,
So after env is created, conda activate env_name, then conda install packages and then pip install the packages.
When I find packages are in conflict (say pkgA, pkgB, pkgC), I normally just do: conda install pkgA pkgB pkgC and let conda to pick and choose the one to resolve the issues. (This does not always though...)
This solved my problem.
I created a new environment using this:
"What worked for me :
run spyder from the environment (after source activate)
go to
Tools --> preferences --> python Interpreter and select the python file from the env you want to link to spyder ex : /home/you/anaconda3/envs/your_env/bin/python
Worked on ubuntu 16, spyder3, python3.6."
[LINK: https://stackoverflow.com/questions/30170468/how-to-run-spyder-in-virtual-environment/30170469#30170469]
Then proceed with installing the package I need. The issues were miraculously gone :)
Then I typed this in the anaconda environment
spyder activate MyEnvironment
