Strange ocp-index conflict and opam --fixup wants to remove everything.

Here's the interaction (cudf file is here):

I noticed a similar issue last night where an opam upgrade cycle wanted to remove everything. Not sure if it's related.

Updates available for 4.01.0, apply them with 'opam upgrade':

Me too. I suspect this is a widely hit problem.

Very hard to repro ... I've tried to install various combination of ocp-build and ocp-indent and everything works fine. @AltGr is in vacation, but I can try to have a deeper look at it tomorrow if that bug is blocking people.

[dbuenzli]

I have ocp-indent 1.4.2 and ocp-build 1.99.8-beta. Here's the end of upgrade with --debug.

[dbuenzli]

Strange, I did an opam remove ocp-indent and then opam install ocp-indent at that point I was proposed to upgrade to ocamlfind 1.5.5, thus everything reinstalled and things are now ok.

[yminsky]

Any progress on this? I can presumably fix by blowing away my .opam directory and reinstalling, but it's pretty bad that this upgrade is breaking everyone's installs.

I'm using the latest opam from brew, to no avail, for what it's worth.

[samoht]

Try opam upgrade ocamlfind and see if things go better. The cause of the bug is #1834
