GPG issue when building docker image

[usamah82]

When attempting to build the image locally by running

docker build -t blacktangent/circleci-ruby:2.6.1-stretch-pgclient10.5-node10.15.1-browsers circleci-ruby/2.6.1-stretch-pgclient10.5-node10.15.1-browsers/

I encountered the following error:

Step 8/25 : RUN set -ex   && for key in   94AE36675C464D64BAFA68DD7434390BDBE9B9C5   FD3A5288F042B6850C66B31F09FE44734EB7990E   71DCFD284A79C3B38668286BC97EC7A07EDE3FC1   DD8F2338BAE7501E3DD5AC78C273792F7D83545D   C4F0DFFF4E8C1A8236409D08E73BC641CC11F4C8   B9AE9905FFD7803F25714661B63B535A4C206CA9   56730D5401028683275BD23C23EFEFE93C4CFFFE   77984A986EBC2AA786BC0F66B01FBB92821C587A   8FCCA13FEF1D0C2E91008E09770F7A9A5AE15600   ; do   gpg --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys "$key" ||   gpg --keyserver hkp://ipv4.pool.sks-keyservers.net --recv-keys "$key" ||   gpg --keyserver hkp://pgp.mit.edu:80 --recv-keys "$key" ;   done

Some fails on

gpg: cannot open '/dev/tty': No such device or address

Some fails on

gpg: keyserver receive failed: No data

Tried the fix by adding --no-tty or --batch option but it didn't work for me. Perhaps someone could also try the same (I may not have the proper local setup?) / or suggest another workaround?
