I don’t know exactly what is the most salient thing from the install log so I’m including all of it. The resulting error is:
ERROR: for symbolicator-cleanup Service 'symbolicator-cleanup' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y --no-install-recommends cron && rm -r /var/lib/apt/lists/*' returned a non-zero code: 100 Cleaning up...
I’d include the entire thing but there’s a limit on characters. There’s an interesting potential clue in the logs in this line (from sentry-onpremise-local:latest):
W: Failed to fetch http://deb.debian.org/debian/dists/stretch/InRelease Could not resolve 'deb.debian.org' W: Failed to fetch http://deb.debian.org/debian/dists/stretch-updates/InRelease Could not resolve 'deb.debian.org' W: Some index files failed to download. They have been ignored, or old ones used instead. Reading state information... Reading package lists... Building dependency tree... Reading state information... Package cron is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
Also from same build:
debconf: delaying package configuration, since apt-utils is not installed
The forum really needs attachments so one can upload a log.
