The current Gentoo stable version of backuppc (4.4.0-r1) exhibits a nasty bug in that any change in the configuration initiated from the CGI interface mangles the configuration file by replacing many [...] and {...} with (...). As a result the configuration becomes unusable and so backuppc crashes and/or the CGI interface becomes unusable. The problem is caused by an incorrect second argument to Data::Dumper in a few places. An upstream patch to correct the issue is available at https://github.com/backuppc/backuppc/commit/2c9270b9b849b2c86ae6301dd722c97757bc9256 Reproducible: Always Steps to Reproduce: 1. Launch the backuppc CGI interface https://<host>/BackupPC_Admin 2. Go to any page that edits the configuration, such as https://<host>/BackupPC_Admin?action=editConfig&newMenu=hosts or https://<host>/BackupPC_Admin?action=editConfig 3. Edit something (such as adding a host) and save Actual Results: In /etc/BackupPC/config.pl many [...] and {...} constructs are replaced by (...). For example $Conf{WakeupSchedule} = [ 23, 0, 1, 2, 3, 4 ]; becomes $Conf{WakeupSchedule} = ( 23, 0, 1, 2, 3, 4 ); As a result the backuppc process crashes with errors such as Can't use string ("4") as an ARRAY ref while "strict refs" in use at /usr/bin/BackupPC line 868. Expected Results: The new configuration is saved correctly and backuppc continues to operate normally.
