Bug#776774: apt: Don't throw away cronjob stderr output on regular verbosity levels
Package: apt
Version: 1.0.9.6
Severity: important
Hello,
when using the /etc/cron.daily/apt cronjob with APT::Periodic::Verbose
set to anything below 3 it's basically impossible to catch errors
because stderr output is thrown away (XSTDERR="2>/dev/null" which is
used at various apt-get commands later on).
Unfortunately this also means that all errors from apt-get update get
discarded, which in turn means that no metadata update happens, ever.
To reproduce, just configure APT to use a non-existing proxy like for
example
Acquire::http::Proxy "http://localhost:48080";;
and run the cronjob (of course having enabled APT::Periodic in the
APT config). The cronjob will happily exit with 0 and not produce any
output.
Cheers
Wolfgang
PS: Obviously it's also questionable if it's the right thing to do for
apt-get update to exit with 0 when not a single configured repository
can be reached.
