    1. The Docker does not depend on apt-cacher-ng package. Ref: #14002.

    2. Do not try to install the Docker if docker.service is detected on the system (e.g., the Docker was installed manually). Fix #13623 (comment) by Sjors.

    3. Prevent the setting of more than one environment variable for the gitian-builder (an alternative to #13999). E.g., USE_LXC being set shadows USE_DOCKER; for details see gitian-builder/libexec/make-clean-vm:

    0VMSW=KVM
1if [ -n "$USE_LXC" ]; then
2    VMSW=LXC
3elif [ -n "$USE_VBOX" ]; then
4    VMSW=VBOX
5elif [ -n "$USE_DOCKER" ]; then
6    VMSW=DOCKER
7fi
    1. The gitian-builder/bin/gverify script returns the exit code 1 if a signature verification ends with ‘BAD SIGNATURE’ or ‘MISMATCH’ by design. This PR allows to see the verification results for all signatures without a premature fail of the gitian-build.py script. Ref: #14014.

    Just noting that external documentation would have to be updated to reflect this change.
    hebasto commented at 6:37 pm on September 5, 2018:

    All related documentation which describes this script options is located in the https://github.com/bitcoin-core/docs repository. Therefore, IMO, there is nothing to add to this PR regarding docs. Or did I miss something?

    I’ll submit an appropriate PR to the https://github.com/bitcoin-core/docs repository in a timely manner.

    Why should this not fail if there is a mismatch?
    hebasto commented at 10:09 pm on November 2, 2018:

    The gitian-builder/bin/gverify script returns the exit code 1 if a signature verification ends with ‘BAD SIGNATURE’ or ‘MISMATCH’ by design.

    From the Python docs:

    If the return code was zero then return, otherwise raise CalledProcessError.

    Wait for command to complete, then return the returncode attribute.

    MarcoFalke commented at 10:17 pm on November 2, 2018:

    I understand that by this change the return code is ignored, but I’d like to understand why.

    If the signatures are bad or the hashes mismatch, the verification should fail.

    hebasto commented at 10:24 pm on November 2, 2018:
    I mean script fails. You cannot see the result of verifying of the signatures that remain. With this commit script will not fail and you will see the results for all signatures.
    MarcoFalke commented at 5:22 pm on November 15, 2018:
    Fine, if you want to print the result for all signatures, but please don’t change the behaviour (fail on non-zero exit code) of the script.

    @MarcoFalke Thank you for your review.

    Fine, if you want to print the result for all signatures, but please don’t change the behaviour (fail on non-zero exit code) of the script.

    Fixed. Would you mind re-reviewing?

  32. Fix Docker related issues for gitian-build.py 
    The Docker does not depend on apt-cacher-ng package.
Do not try to install the Docker if docker.service is detected on the
system (e.g., the Docker was installed manually).
Also small style corrections were applied.

  33. Set/unset USE_LXC, USE_VBOX, USE_DOCKER explicitly 
    This prevents the setting of more than one environment variable for the
gitian-builder (e.g., USE_LXC being set shadows USE_DOCKER; for details
see gitian-builder/libexec/make-clean-vm).

  34. Fix gitian-build.py --verify option 
    The gitian-builder/bin/gverify script returns the exit code 1 if a
signature verification ends with 'BAD SIGNATURE' or 'MISMATCH' by
design. This commit allows to see the verification results for all
signatures without a premature fail of the gitian-build.py script.

    Rebased. @MarcoFalke

    This can be achieved without a breaking change via args.lxc = not args.kvm and not args.docker

    Dropped new --virtualization option. So, no breaking changes now.

    Also “do not warn about macOS build on setup” feature dropped in favor of #15236.

    Commit messages have been brushed. PR description updated.
