Channel specific package + strict priority currently not compatible

[wolfv]

We might need to do some additional tricks to make the following work:

.condarc:

channels:
- conda-forge
channel_priority: strict

mamba create -n blabla quantstack::sphinx

Throws an error because it can't install quantstack::sphinx due to strict channel priority.

I just checked, and conda has the same problem ... not sure if we shoudl chagne that.

[opoplawski]

Just ran into this myself.

Looks like the conda issue is conda/conda#9642 which appears to have been accepted as a bug.

[opoplawski]

Well, it was closed as stale. This would be very helpful to me. I'm facing an issue where mysql-connector-python appears to have been retired from the main channel, so I need to grab it from conda-forge, but otherwise I want to use packages from main over conda-forge.

I cannot reproduce this issue with 2.0.6:

channels:                                                                                                                                                               
  - conda-forge
channel_priority: strict
