I experienced an interesting problem: on a Debian Jessie host with squidguard: update-squidguard threw the following error-message:
root@34697f9f06a2:/# update-squidguard
/usr/sbin/update-squidguard: 69: test: dbhome: unexpected operator
Rebuild SquidGuard database - this can take a while.
On Debian Wheezy it returns with the following error:
root@34697f9f06a2:/# update-squidguard
/usr/sbin/update-squidguard: 95: /usr/sbin/update-squidguard: cannot create dbhome /var/lib/squidguard/db/../dbversion: Directory nonexistent
The admin configured tabs instead of whitespaces in the following line of his squidguard.conf:
dbhome /var/lib/squidguard/db
Even if squidguard accepts tabs, update-squidguard does not and apt-get upgrade would not work if squidguard would be upgraded because it calls update-squidguard. The problem seems to be in /usr/sbin/update-squidguard at the following line:
DATADIR=$(grep ^dbhome ${CONFDIR}/${CONFFILE} | cut -d' ' -f2)
This could be easily fixed by using the following code:
DATADIR=$(grep ^dbhome ${CONFDIR}/${CONFFILE} | sed 's/\t/ /' | cut -d' ' -f2)
This would make update-squidguard more robust. I wrote the maintainer, but since it is recommended to use whitespaces he might not fix this.
