Fix environment_ubuntu.yml

[TitouanTyack]

Hello there,

Ubuntu 22 user here. I tried to setup conda env with environment_ubuntu.yml and it didn't work :

conda env create -f environment_ubuntu.yml
2 channel Terms of Service accepted
ERROR conda.plugins.manager:detect_environment_specifier(599): EnvironmentSpec hook: an error occurred when handling 'environment_ubuntu.yml' with plugin 'explicit'. 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte
Channels:

 - conda-forge
 - defaults
Platform: linux-64
Collecting package metadata (repodata.json): done

  - package intel-openmp-2023.1.0-hdb19cb5_46305 requires zlib >=1.2.13,<1.2.14, but none of the providers can be installed
Could not solve for environment specs
The following packages are incompatible
├─ intel-openmp =2023.1.0 * is installable and it requires

├─ libintl =0.22.5 * does not exist (perhaps a typo or a missing channel);
└─ libzlib =1.3.1 * is not installable because there are no viable options
   ├─ libzlib 1.3.1 would require
   │  └─ zlib ==1.3.1 *, which conflicts with any installable versions previously reported;
   ├─ libzlib 1.3.1 would require
   │  └─ zlib ==1.3.1 *_1, which conflicts with any installable versions previously reported;
   ├─ libzlib 1.3.1 would require
   │  └─ zlib ==1.3.1 *_2, which conflicts with any installable versions previously reported;
   └─ libzlib 1.3.1 would require
      └─ zlib ==1.3.1 *_0, which conflicts with any installable versions previously reported.

I removed the zlib version specification and removed these:

- intel-openmp=2023.1.0
- libintl=0.22.5
- libintl-devel=0.22.5
- libzlib=1.3.1

I also change the encoding type to remove the first line of the ouput of the command (not mandatory) :

iconv -f UTF-16 -t UTF-8 environment_ubuntu.yml -o environment_ubuntu_fixed.yml

and it worked !

For your information I did this because I wanted to use JOBuilder.py locally and it worked well with this conda environment, I've been able to generate a JO that worked for the BPS stack.

If you want I can open a pull request with the modified environment_ubuntu.yml file.

Thank you.
