Python 3.x upgrade has broken yum on centos7-devtoolset7

[thegecko]

Since the python 3.x upgrade, yum seems to be broken on the centos7-devtoolset7 image.

Using the following dockerfile:

FROM ghcr.io/prebuild/centos7-devtoolset7:2.1.0
USER 0

RUN yum install -y libudev-devel

USER node

Yields errors with yum accessing the correct python version:

#6 2.378   File "/usr/libexec/urlgrabber-ext-down", line 28
#6 2.378     except OSError, e:
#6 2.378                   ^
#6 2.378 SyntaxError: invalid syntax

I'll try some sed magic...

I thought I handled that with:

docker-images/centos7-devtoolset7/Dockerfile

Line 9 in 4b8968f

sed -i 's/#!\/usr\/bin\/python/#!\/usr\/bin\/python2/' /usr/bin/yum && \

But I don't remember the extent to which I tested that.

Seems it needs to be replaced in a different script, too.

#29 fixes the issue
