[Caml-list] opam corrupted my sources.list.

[Caml-list] opam corrupted my sources.list.

[Hendrik Boom]

Well, technically, it was the directory /etc/apt/sources.list.d that 
got an unwanted file:

opam.list

and I'm guessing that it was opam from the name of that file.

It contained the line:

deb http://download.opensuse.org/repositories/home:/ocaml/Debian_7.0/ /

This caused havoc with my system because I am *not* running Debian or 
suse, but devuan, a Debian derivative, and I am now stuck with 
aptitude tring to install a *huge* collection of unwanted and 
inconsistent packages because the dependencies in my system are 
different from those in the openuse repository.

I am still unable to use aptitude to do routine upgrades.

Why does opam do this?  And, is it indeed opam?

Perhaps devuan needs to do something special with ocaml-related 
packages, but until I know what's happening and why it's hard to know 
where to start.

This is not related to opam. It is a repository of Debian-style
packages visibly intended for Ubuntu users, authored by Anil
Madhavapeddy who hosted then on opensuse repositories. My guess is
that you enabled this repository manually to get 4.02.1 OCaml packages
at a time where they were not yet packaged in your official Debian
repository.

The best way to setup an OCaml *development environment* today is to
install opam (either through your distribution package manager, as a
binary, or from sources built from a distribution-packaged OCaml
version), and then install ocaml-$version switches in opam. (For
end-user packages written in OCaml, distribution packages are still
very important.)

It would surprise me if it were.  In fact, it did surprise me to think it did.

I have never created a file in /etc/apt/sources.list.d myself.
The only file near there I have edited is /etc/apt/sources.list itself.

Then some other action must have done this on my behalf, apparntly not opam.
I installed opam from the proper devuan repository.

So I have to conclude that I just do not know why the corruption happened.

Too bad.

Wild speculation:  Could Debian have just taken over the packages in 
that repository on opensuse, and then devuan got it from Debian?  That 
would be surprising, but it is at least plausible.

Apparently, you, or someone else on your machine, or some script you
ran as root, followed the OPAM installation procedure for Debian
described here:
https://opam.ocaml.org/doc/Install.html#Debian

The conclusion is "don't do that if you're not running Debian".  There
are other ways of installing OPAM, described on this page, that should
work with whatever distro you feel like using.

At any rate, this has nothing to do with OCaml itself, and not much
with OPAM, so let's take this discussion off caml-list.
