  • Plesk 9.5 for Linux/Unix


Packages psa-mail-pc-driver and psa-mail-qc-driver do obsolete each other. This causes problems while running update of Parallels Plesk Panel PVC containers with `vzpkg update CTID`

Actual result:
# yum update
 psa-mail-qc-driver     x86_64    1.0.0-cos5.build95101209.08    plesk95   736 k
    replacing  psa-mail-pc-driver.x86_64 1.0.0-cos5.build95101022.10
Expected result:
# yum update
  psa-mail-pc-driver    x86_64   1.0.0-cos5.build95101209.08     plesk95   2.0 M


As possible workaround you can prevent vzpkg from installing psa-mail-pc-driver by adding it into exclusion list /etc/vztt/vztt.conf

However, if you have other PVC containers on the node which uses postfix MTA, it is needed to exclude psa-mail-qc-driver in vztt.conf before updating them.
