Bug#502318: apt: test for locked cache not quite right
Package: apt
Version: 0.7.16+b1
Severity: normal
File: /etc/cron.daily/apt
The /etc/cron.daily/apt job emailed me this error:
/etc/cron.daily/apt:
/etc/cron.daily/apt: could not lock the APT cache while performing daily cron job.
Is another package manager working?
run-parts: /etc/cron.daily/apt exited with return code 1
which I tracked down to the following segment (line 205ff) from
the /etc/cron.daily/apt shell script:
# check if we can access the cache
if ! apt-get check -q -q 2>/dev/null; then
# wait random amount of time before retrying
random_sleep
# check again
if ! apt-get check -q -q 2>/dev/null; then
echo "$0: could not lock the APT cache while performing daily cron job. "
echo "Is another package manager working?"
exit 1
fi
fi
I had just done 'aptitude upgrade' and hpijs hadn't upgraded properly
because it needed to overwrite a file from hpijs-gui. So 'apt-get
check' failed -- not because of any problem accessing the cache but
rather because of the hpijs problem.
The preceding shell code from /etc/cron.daily/apt does not distinguish
between those failures, so it sleeps a random amount of time, fails
again for the same reason, (mistakenly) concludes that it cannot lock
the APT cache, and then exits with an error code.
I'm not sure of the right fix.
