apt-get via cron not working? - zhuanyi - 08-16-2013
I have a very simple apt-get script that has a one line code like:
apt-get update && apt-get -y upgrade && apt-get -y dist-upgrade
And I have set it up via cron to run every evening, using crontab -e:
0 3 * * * /root/apt.sh
However when I ran the script manually after a month or so, I get over 50 package updates, which seems to show that the cron did not work properly.
What I can confirm so far:
1. The script is working when running manually
2. The cron is working since I had other cron jobs running and they all seem to work
I am on Debian 6.
Anyone could help?

Can't find the problem, but why do you "apt-get -y upgrade && apt-get -y dist-upgrade" ?

Sorry....but why not?
You mean why the -y part of why the upgrade/dist-upgrade part?

I mean why update and then dist-upgrade ?
From the man pages :
Code:
dist-upgrade
In addition to performing the function of upgrade, this option also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones, if necessary.Which means, that dist-upgrade does everything and upgrade is redundant !

Interesting...I was always under the impression they do something different because when I runs upgrade followed by dist-upgrade, I get quite a few packages to upgrade...
Guess now I learnt something new today
But I guess the issue here is apt just does not seem to run via Cron at all. Like nothing was updated even though other cron jobs runs on a daily basis.
