package update-manager 1:0.81 failed to install/upgrade: ErrorMessage: SystemError in cache.commit(): E:Sub-process /usr/bin/dpkg returned an error code (1)

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the log files from '/var/log/dist-upgrade/' to this bugreport as attachments to your bug report? Thanks in advance.

the Solution I've came to - is to reinstall manually upgrade-manager. And that what i did finally....

Actually the problem this updating of torrentflux repeating again and again after installations/updates in
"
dpkg: не удалось обработать параметр torrentflux (--configure):
 подпроцесс post-installation script возвратил код ошибки 1 "

DBConfig is not working correctly I guess

(Before Upgrades it was not been appeared )

Here I've got it - dbconfig-common: writing config to /etc/dbconfig-common/torrentflux.conf
Replacing config file /etc/torrentflux/config-db.php with new version
creating database backup in /var/cache/dbconfig-common/backups/torrentflux_2.1-7.mysql.
unable to connect to mysql server.

I have MySQL 5 server installed onboard.

The cause of the failure basically translated to english is:
=====
Adjusted package torrentflux (2.3-2ubuntu1) ...
dbconfig-common: writing config to / etc / dbconfig-common / torrentflux.conf
Replacing config file / etc / torrentflux / config-db.php with new version
creating database backup in / var/cache/dbconfig-common/backups/torrentflux_2.1-7.mysql.
sanity check failed for mysql.
dpkg: failed to process the option torrentflux (- configure):
  subprocess post-installation script returned error code 1
=====

affecting to torrentflux . You need mysql-server and mysql-client in order to install and use torrentflux. Latest version should handle it more nicely.

Are you able to reproduce it in hardy + ?

Thanks.
