Makefile:24: *** Unexpected opam version (found: 2.1.0, expected: 2.0.*). Stop

Question

Just followed the instruction here https://opentezos.com/deploy-a-node/installation#install-tezos-dependencies-1

ran into this issue

Makefile:24: *** Unexpected opam version (found: 2.1.0, expected: 2.0.*). Stop.

any suggestions?

Answer 1

Install, for instance, opam version 2.0.9. To do this:

$ wget https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh
$ chmod +x install.sh
$ ./install.sh --version 2.0.9

Once this is done, you may need to remove/re-create $HOME/.opam directory.
