There's a debian package to do this, but I had already rolled my own
when I came across it. I have in /etc/cron.d/apt-upgrade the following
entry:
-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----
UPGTMP="/var/tmp/.outf.apt-upgrade"
30 7,15,23 * * * root /usr/local/sbin/apt-upgrade | tee "$UPGTMP"
-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----
which tries to download upgraded packages and send the results to me by
mail, as well as storing them in a log file.
The /usr/local/sbin/apt-upgrade script checks to see if it is already
running, takes access failures into account by retrying a certain number
of times, and downloads all the updated packages (the installation
of the packages should *never* be done automatically).
It goes like this:
-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----8<-----
#!/bin/bash
BASE="/var/tmp"
LOCK="$BASE/.lock.apt-upgrade"
DONE="$BASE/.done.apt-upgrade"
MAXTRIES="5" # retry limit
SLEEPSECS="300" # seconds to sleep between retries
SEP="----------------------------------------"
echo $SEP ; echo "$0" ; echo $SEP ; date ; echo $SEP ; echo
if [ -e $LOCK ] ; then
echo
echo "ERROR: already running ($LOCK exists, process `cat $LOCK`)."
echo "Exiting..."
echo
exit
fi
TRIES="1"
echo -n "$$" > $LOCK
while ! apt-get update ; do
echo ">>>"
if [ $TRIES -eq $MAXTRIES ] ; then
echo ">>> Try $TRIES: there were errors. Try limit reached, giving up."
echo ">>>"
break
else
echo ">>> Try $TRIES: there were errors. Sleeping for $SLEEPSECS s..."
echo ">>>"
sleep $SLEEPSECS ; TRIES=$(($TRIES + 1))
fi
done
echo ; echo $SEP ; date ; echo $SEP ; echo
TRIES="1"
while ! apt-get -d -y -u dist-upgrade ; do
echo ">>>"
if [ $TRIES -eq $MAXTRIES ] ; then
echo ">>> Try $TRIES: there were errors. Try limit reached, giving up."
echo ">>>"
break
else
echo ">>> Try $TRIES: there were errors. Sleeping for $SLEEPSECS s..."
echo ">>>"
sleep $SLEEPSECS ; TRIES=$(($TRIES + 1))
fi
done
echo ">>>" ; echo ">>> Done after $TRIES tries." ; echo ">>>"
echo ; echo $SEP ; date ; echo $SEP ; echo
rm -f ${DONE}*
mv $LOCK ${DONE}.$(date +%Y-%m-%d-%H:%M)
