Original GitHub issue: https://github.com/FiloSottile/mkcert/issues/222

I'm running mkcert as a local Docker container user in order to get it installed into the NSS DB so that it will work with headless Chrome (and Selenium) in a Docker container. I've used this approach successfully in a different container, but in this one (selenium/standalone-chrome-debug) I'm hitting a strange error that I'm not quite sure how to diagnose or debug.

Command: output

$ TRUST_STORES=nss mkcert -install
/usr/local/bin/mkcert: 1: /usr/local/bin/mkcert: Not: not found

From what I can tell, the tool is getting unexpected output and trying to execute that output. When I tried another invocation of this (with sudo -E in case permissions were an issue), it failed on line 26 of sh.

It's running Ubuntu:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.2 LTS
Release:        18.04
Codename:       bionic

I install mkcert in the Dockerfile with:

ENV MKCERT_VERSION=v1.4.0
RUN sudo su -c 'apt-get update && \
  apt-get install -y curl openssl libnss3-tools && \
  curl -sSL https://github.com/FiloSottile/mkcert/releases/download/$MKCERT_VERSION/mkcert-$MKCERT_VERSION-linux-amd64 -o /usr/local/bin/mkcert && \
  chmod +x /usr/local/bin/mkcert && \
  apt-get purge -y curl && apt-get clean && \
  chmod +x /selenium2-startup.sh'

And I see paths to the expected binaries with which, etc.

Ah. The contents of /usr/local/bin/mkcert are Not Found, so I guess the URL changed from last time I used it. That'll do it! Closing this.

P.S. link was fine, my switch to single quotes when porting my Dockerfile from headless Chrome to Selenium was the culprit. Obviously a literal $MKCERT_VERSION won't work.

You should try "./mkcert -install"
