Thanks, it works with

build() {
 cd /usr/bin && sudo ln -sf python2 python && cd - && cd /usr/lib/ && sudo rm -rf python && sudo ln -sf python2 python && cd -
  cd "hg"

  make all
  make -C "contrib/chg"

in the mercurial-hg PKGBUILD, so for me the solution is to use self-compiled mercurial with python 2.7 for cloning and compiling firefox-nightly-hg.

Any other mercurial version uses system python 3 / python 3.8 which didn't work for me.

I also installed python-virtualenv and python2-virtualenv, don't know if it's necessary.

@hugegameartgd : Normally it should compile with python 2 I find it amazing who compiles it for you with python 3

I get this error when cloning (output is translated):

[user@archlinux firefox-nightly-hg] $

I tried this config in ~/.hgrc:

fsmonitor =
purge =
sparse-revlog = no

I also tried it with mercurial, mercurial-python3, mercurial-hg or mercurial-stable installed. Upgrading the /src repo with hg debugupgraderepo --run also didn't fix it.

Seems to be an upstream issue either with firefox or mercurial (or python).
