Hello Col., Thank you for taking the time to file this bug report and help us make Ubuntu better.
The error messages in DpkgTerminalLog.txt that show this failure are here: Selecting previously deselected package mail-stack-delivery. Unpacking mail-stack-delivery (from .../mail-stack-delivery_1%3a1.2.12-1ubuntu7_all.deb) ... /var/lib/dpkg/tmp.ci/preinst: 74: /etc/dovecot/conf.d/01-dovecot-postfix.conf: Permission denied /var/lib/dpkg/tmp.ci/preinst: 74: /etc/dovecot/conf.d/01-dovecot-postfix.conf: Permission denied /var/lib/dpkg/tmp.ci/preinst: 74: /etc/dovecot/auth.d/01-dovecot-postfix.auth: Permission denied /var/lib/dpkg/tmp.ci/preinst: 74: /etc/dovecot/auth.d/01-dovecot-postfix.auth: Permission denied rmdir: failed to remove `/var/backups/dovecot-postfix/': Directory not empty dpkg: error processing /var/cache/apt/archives/mail-stack-delivery_1%3a1.2.12-1ubuntu7_all.deb (--unpack): subprocess new pre-installation script returned error exit status 1 This file attempts to rename these files from dovecot-postfix to mail- stack-delivery if they exist. Is it possible that you have changed the permissions on the directory or files that would cause these errors? Maybe /etc is mounted readonly? The permission denied is odd because these scripts run as root. I just tested upgrading Lucid -> Maverick with dovecot-postifx installed, and it renamed the file without any errors. Col, if you could please post the result of ls -lR /etc/dovecot That would help us determine whether or not the permissions have been locally modified in a way that breaks the install script, or whether the install scripts need to be changed. Marking Incomplete pending respond from Col.
