When using a chroot created for SBuild, the SBuild commands (‘sbuild’,
‘sbuild-update’, ‘sbuild-shell’, etc.) emit a stream of repeated
messages about alias associations.

These messages are interspersed in with other SBuild output and the
output from the commands it runs. This makes the output unusably
crowded with warning messages.

=====

If these associations are a problem, what needs to be done to correct
that problem?

If these associations are not a problem, I would expect that there
should not be messages spamming the console output.

Hi,

Quoting Ben Finney (2019-02-03 22:51:27)

it seems that this message comes from schroot and not sbuild. Thus, reassigning.

https://sources.debian.org/src/schroot/1.6.10-6/sbuild/sbuild-chroot-config.cc/?hl=59#L59

Thanks!

cheers, josch

Thanks. I am also altering the metadata for the version of ‘schroot’
installed.

Hello,

I ran into the same problem myself today, and found this bug report.

The problem started after I have added a second sbuild chroot with the
following command:

    sudo sbuild-debian-developer-setup --suite=stable

And, thanks to your hint that the issue is actually schroot related, I
found in /etc/schroot/chroot.d/ two config files
unstable-amd64-build-XXXXXX and stable-amd64-build-XXXXXX, both
created by sbuild-debian-developer-setup.  And, sure enough, both
files contain the line

    aliases=UNRELEASED,sid

which is correct for unstable but inappropriate for stable.  schroot's
"Alias already associated" warnings are valid.  The actual bug is
found somewhere else, from whomever or from whatever command that
created those schroot chroot.d config files.

And, sure enough, we can find in /usr/bin/sbuild-debian-developer-setup:

https://sources.debian.org/src/sbuild/0.80.0/bin/sbuild-debian-developer-setup/#L56-L57

when it calls sbuild-createchroot, it indiscriminately adds the flags
