some files went missing after performing packages updates
I was wondering if I could get some help here. Prior to packages updates, I had my postfix, dovecot and roundcube all working just fine. After running the command below from the command line on Ubuntu Server 12.04 LTS 32bit, my postfix does not want to start anymore.
To update those packages, I run:
$ sudo aptitude safe-upgrade
To start postfix,
$ sudo /usr/sbin/postfix start
postfix: fatal: chdir(/usr/libexec/postfix): No such file or directory
The error is right that I could no longer find libexec under /usr directory. It's been deleted.
I don't know what to do apart from considering re-install my postfix. My question is what's the better way of installing updates on Ubuntu Server.
Any help would be greatly appreciated.
