You can use the version from EPEL, which is still at 1.x and is maintained (1.10.17 in testing)

In my archives I only have old versions

See yum documentation and exclude/includepkgs directives.

BTW, I have not enough information about what you are running (at least distribution and  version)

For now you can download old versions from
http://rpms.remirepo.net/store/composer/

Will have to think to something simpler
Perhaps I should have created a stream (module) for it, need to think about this

After more thinking (and a good lunch), I choose to remove composer from "remi" repository and to provide it as a module (so in "remi-modular")

"dnf install composer" will install latest version from default stream, so v2.0.4

"dnf update" will also enable v2 (even when installed from "remi", before modular changes, would have be a blocker for me if not working)

For people wanting to keep v1

dnf module reset composer
dnf module install composer:1

And, later, to upgrade to v2

dnf module reset composer
dnf module install composer:2

"dnf update" will preserve major version, as module was desinged for.

P.S. of course latest versions (1.10.17 and 2.0.4) are available in their respective stream.

It is already done.

   dnf module reset composer
   dnf module install composer:1

Should be enough (when used mirror will be synced with primary server)
