I'm trying to install that to build a tezos-client from scratch

logart@logart2:~$ sudo sh <(curl -sL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh)
sh: 0: Can't open /dev/fd/63

Any idea on how to fix that? Why is saying it can't open that? I would appreciate any help

You can try to split up the process in 2 step to see where the error is:

curl -L -o install.sh https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh
sh ./install.sh
sudo sh ./install.sh             # If the above complains about access rights
