[Message part 2 (message/rfc822, inline)]
Package: backuppc
Version: 4.4.0-3
Severity: normal
Tags: patch
X-Debbugs-Cc: debianbugs@kurgan.org
Dear Maintainer,
Backuppc, installed from the package on a new server (so no
upgrade/update from previous versions) fails with this message:
# apt install backuppc
[... omitted output...]
Creating config file /etc/backuppc/config.pl with new version
Starting backuppc...BackupPC cannot be started because important parameters are missing from config.pl.
If you just upgraded BackupPC, please update /etc/backuppc/config.pl.
invoke-rc.d: initscript backuppc, action "start" failed.
dpkg: error processing package backuppc (--configure):
installed backuppc package post-installation script subprocess returned error exit status 1
This happens because the init script for backuppc contains this check:
# Check for incompatible old config files
check_old_config()
{
BAD=0
CONF=/etc/backuppc/config.pl
grep -q IncrLevel $CONF || BAD=1
if [ "$BAD" = "1" ]; then
echo "BackupPC cannot be started because important parameters are missing from config.pl."
echo "If you just upgraded BackupPC, please update /etc/backuppc/config.pl."
exit 1
fi
}
But it seems that this check is not needed anymore in Backuppc 4, it was
something related to V2 -> V3 upgrade.
This check is called when starting/restarting backuppc. By commenting
out the call to check_old_config under start and restart, backuppc
works.
This will leave you with an unconfigured package in apt, so after
modifying the init script you'll also have to run:
rmdir /var/lib/backuppc/pc/localhost
apt install
Kind regards
Fabio Muzzi
