[pkg-go] Bug#842380: gitlab-ci-multi-runner: mk-prebuilt-images.sh fails at install time

[Vincent Danjean]

Package: gitlab-ci-multi-runner
Version: 1.7.1+dfsg-1
Severity: important

  Hi,

  During the installation of the Debian package, mk-prebuilt-images.sh.
There is two problems:
1) the cdebootstrap command is failing. I do not know why
  but the current result (can be easily reproduced) is :
  # cdebootstrap     --flavour=minimal     --exclude="dmsetup,e2fsprogs,init,systemd-sysv,systemd,udev"     --include="bash,ca-certificates,git,netcat-traditional"     stable ./debian-minbase
  [...]
  P: Configuring package apt
  P: Configuring helper cdebootstrap-helper-apt
  E: Internal error: install
  #

  The mk-prebuilt-images.sh script continues but produce a image that does not
  have the required tools (git in particular)

  => docker is unusable.

2) mk-prebuilt-images.sh does not report this problem and the postinst
  does not fail (hence the 'important' severity)
  It tooks me lot of time to discover that
  1) a special docker image is used to clone the repo
  2) this special image is corrupted (the 'E: Internal error: install' can
    be seen in the log file whose name is displayed during the package
    configuration). But, as the package installs fine, I do not suspect
    a problem here until I really llok in depth.

Note that this is a Debian specific bug, as I eventually found:
https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/1669

  Perhaps, this bug can be duplicated and the first part reassigned
to cdeboostrap (the second part is really about this package)
if the cdeboostrap invocation is correct (I do not know cdeboostrap).


  Regards,
    Vincent
