this worked for me:

# -- Get metalib for coq-8.10 via commit when getting it through git submodules (unsure if needed)
#rm -rf coq-projects/metalib
#git submodule add -f --name coq-projects/metalib https://github.com/plclub/metalib.git coq-projects/metalib
# - use the one with commit even if it doesn't work just to document the commit explicitly in the .modules file
git submodule add -f --name coq-projects/metalib git+https://github.com/plclub/metalib.git#104fd9efbfd048b7df25dbac7b971f41e8e67897 coq-projects/metalib
git submodule update --init coq-projects/metalib
(cd coq-projects/metalib && git checkout 104fd9efbfd048b7df25dbac7b971f41e8e67897)
(git rev-parse HEAD && cd ..)
# Metalib doesn't install properly through opam unless we use a specific commit.
eval $(opam env --switch=coq-8.10 --set-switch)
(cd coq-projects/metalib && opam install .)

# install it again since I think his code has pointers to a version under deps, could unify with above but it's less work to just accept as is and install it, ref: https://github.com/UCSD-PL/proverbot9001/issues/77
rm -rf deps/metalib
#git submodule add -f --name deps/metalib git+https://github.com/plclub/metalib.git deps/metalib
# - use the one with commit even if it doesn't work just to document the commit explicitly in the .modules file
git submodule add -f --name deps/metalib git+https://github.com/plclub/metalib.git#104fd9efbfd048b7df25dbac7b971f41e8e67897 deps/metalib
git submodule update --init deps/metalib
(cd deps/metalib && git checkout 104fd9efbfd048b7df25dbac7b971f41e8e67897)
(git rev-parse HEAD && cd ..)
# Metalib doesn't install properly through opam unless we use a specific commit.
eval $(opam env --switch=coq-8.10 --set-switch)
(cd deps/metalib && opam install .)

# -- Install metalib for coq-8.10 via opam pin (it seems to overwrite the isntalled versions so let's have opam pin be the last one?)
eval $(opam env --switch=coq-8.10 --set-switch)
opam pin add -y coq-metalib git+https://github.com/plclub/metalib.git#104fd9efbfd048b7df25dbac7b971f41e8e67897

@sweirich does your response mean that:

opam pin add -y coq-metalib git+https://github.com/plclub/metalib.git#104fd9efbfd048b7df25dbac7b971f41e8e67897

is not needed? how do you recommend installing/pinning the right version I need?

The tag coq8.10 just identifies a commit. Since you already have found a commit that builds, you can leave it be for now and come back to it later if problems arise because of it. If you do want to use that tag, you get a shorter URL:

opam pin add -y coq-metalib git+https://github.com/plclub/metalib.git#coq8.10
