Installation hanging on downloading repodata

[ruben-arts]

Reproducible example

The problem with this is that I've yet to find a way to reproduce the issue.
The only noteworthy resemblance between the cases this happens to me is that:

• Installing a large set of packages, often ROS environments or similarly large set of dependencies.
• Installing from multiple channels seems to have something to do with it.
• Clean or Full cache doesn't seem to make a difference.
• I can often reproduce it multiple times after another, until the stars ⭐ misalign again, and I can't figure out how to reproduce it anymore.

The result looks something like this in a terminal:

The longest I've left it running was at least 5 minutes, but that doesn't seem to matter.
I've not seen it happen on Sharded repodata and going into debug it often spends a lot of time in the JLAP code but I've been able to pin point it any further, so this is just an idea right now.

Expected behavior

Not getting stuck on downloading repodata.
