@richard - Thanks for the heads up - running as a single command does work.

`mamba create --override-channels --channel=conda-forge --name=mne mne "vtk>=9.2=*osmesa*" "mesalib=21.2.5" -y`

Regarding - why do you pin mesalib - below are the instructions from the website:

We had set this up as a local/nightly testing for mne scripts. So it was working up until a week or two ago. After investigating it, the install turned out to be the issue of why the testing script failed. The single line install does work as a fix.

Thank you for the help.
