Thanks! Can you check the PR files for unwanted changes?

I think this is a longer story, as precompilation would have to be refactored, it calls RegistryInstances.reachable_registries() as well.

In the moment it is switched off in order to see what else could happen. I can try to get a more comprehensive refactoring.

I did run with a patched Pkg in order to see if it works. As a result I get what is in the screenshot, so it seems that there is still another issue:

Ok what do we have now on nightly ?

• the "Connection reset" problem goes away whe using dev'd HTTP.jl
• In the notebook we get the following (for each notebook cell):

For the complete_remote_package problem I used the band-aid proposed in
#2810 (comment)

I think it may make sense to make a PR to Pkg which marks internal things used by Pluto as public in Julia 1.11 sense, making these public interface.

[j-fu]

Ah, nicer stactrace now :)

Now it works with dev'd HTTP.jl - the difference seems to be just one commit which also appears to be about the new Memory type: JuliaWeb/HTTP.jl@040cf0a

Not sure though if returning a view is a good idea. Will need through testing.

As for the Pkg stuff: I would go with @balenamiaa's hack implemented here and fix the Pkg stuff in a different PR when the public interface issues have been resolved.

Guess it remains to wait now for a new release of HTTP.jl ...

[j-fu]

Still need JuliaWeb/HTTP.jl@040cf0a to be released, see JuliaWeb/HTTP.jl#1154

worked locally now under 1.6, 1.11.0-alpha1 and nigthly.

Thanks! Let's work on the method table problems in another PR...

[fonsp]

The method table issue is here #2840

Thanks again @j-fu ! The other issue was only on Julia 1.12 (nightly), I now changed our CI to run the 1.11 preview and 1.12 nightly separately: fabde1f

The new issue was caused by a change in Julia specifically meant to improve Pluto support! Super cool :) JuliaLang/julia#53415
