Issue Error after change postfix to Qmail

[Splatt28]

Hello!
Yeah so.. i've messed up - i've messed up badly.
When trying to change postfix to qmail something broke. Plesk suggested me to use

apt-get install -f

but it didn't work.
In return i got

Removing postfix-pcre (2.11.3-1+deb8u2) ...
/var/lib/dpkg/info/postfix-pcre.prerm: 1: /var/lib/dpkg/info/postfix-pcre.prerm: {:: not found
dpkg: error processing package postfix-pcre (--remove):
subprocess installed pre-removal script returned error exit status 127
Errors were encountered while processing:
postfix-pcre

I've tried this Resolved - Error after change postfix to gmail but it's not finding postfix.* file

mv: cannot stat ‘/var/lib/dpkg/info/postfix.*’: No such file or directory

Any ideas how can i fix that?
