This error about a single package could get it ignored on older opam versions, but I don't think it should ever make the full update command fail. In other words, this should be harmless unless you want to install `pxp`. What were the end of output and return code from opam ?

I'll report the error for ocamlfind+ocp1 ; you can work around it by pinning to a different version, e.g. `opam pin add ocamlfind 1.5.5`.

On the `ocamlfind-ocj` and `ocj-ocamlfind`, that should probably be cleaned up in the opam repository.

Best,
