Package: ucf
Version: 3.0043
Severity: important
Dear Maintainer,
ucfr aborts during an unattended upgrade of dovecot when a diverted
configuration file is present:
> Replacing config file /etc/dovecot/dovecot.conf.mypackage with new
version
> ucfr: Attempt from package dovecot-core to take
/etc/dovecot/dovecot.conf.mypackage away from package mypackage
> ucfr: Aborting.
ucf fails when trying to complete the installation (via another
invocation of apt install):
> Setting up dovecot-core (1:2.2.33.2-1ubuntu4.7) ...
> /usr/bin/ucf: 444: [: missing ]
> grep: ]: No such file or directory
> /usr/bin/ucf: 444: [: missing ]
> grep: ]: No such file or directory
The patch below
* makes ucfr respect diverted configuration files,
* fixes the syntax error in ucf and
* makes ucf correctly detect 'local' diversions, bringing it in line
with stable dpkg-divert output as provided by '--listpackage'.
The patch has been tested successfully with ucf/3.0043 backported to
Ubuntu 18.04.
