I could reproduce it using sbuild (on a different setup).
The root cause is that you use help2man to generate manpages, but
help2man expects both --help and --version to work. And
'run-singularity --version' doesn't work:
$ run-singularity --version
ERROR: Unknown option: --version
That shows in the manpage for run-singularity, that contains garbage as
version number (see man run-singularity | tail -1). This garbage comes
from a call to tput to colorize the error message.
For some reason, this triggers a build failure in sbuild, but not when I
run debian/generate_manpages manually. help2man does some magic with the
output of 'command --version', which I did not fully understand due to
my limited perl-fu. The relevant code is:
# Call program with given option and return results.
sub get_option_value
{
my ($prog, $opt) = @_;
my $stderr = $discard_stderr ? '/dev/null' : '&1';
my $value = join '',
map { s/ +$//; expand $_ }
map { dec $_ }
`$prog $opt 2>$stderr`;
unless ($value)
{
my $err = N_("%s: can't get `%s' info from %s%s");
my $extra = $discard_stderr
? "\n" . N_("Try `--no-discard-stderr' if option outputs to stderr")
: '';
kark $err, $this_program, $opt, $prog, $extra;
}
$value;
}
