Resolved [CentOS 7] Plesk autoinstaller fails when using the local mirror

[burnley]

Hi, I have this rather odd problem on several CentOS 7 servers. Sometime last year I set up a local mirror using Plesk Mirror Setup Tool v3.0 and it's been working without any issues for a while. But around 14th of December 2 of the CentOS 7 servers started to experience MU update failures, basically they can't update using the local mirror, but the update always succeeds if using Plesk's autoinstaller site. What's really puzzling me is that we have other CentOS 7 servers that have never had any updating problem using the local mirror.
No CentOS 5 & CentOS 6 Plesk server is affected.
Environment:
CentOS 7.3, Plesk 12.5.30. The failed servers are stuck on MU #59.
On all CentOS 7 servers we have:
rpm -q psa-autoinstaller
# psa-autoinstaller-3.17.24-centos7.15081214.x86_64
# md5sum `rpm -ql psa-autoinstaller`
f2a00153279f4acf2c4cf3bb0e494b09 /usr/local/psa/admin/bin/autoinstaller
08a304d59c9ba4b0e867abeac28c0cd4 /usr/local/psa/admin/bin/send-error-report
cde2c20393d77c057720fd82586ae6f1 /usr/local/psa/admin/sbin/autoinstaller
Now comes the interesting part:
1. On the servers experiencing the issue we have:
/usr/local/psa/admin/bin/autoinstaller --version
Doing restart of Plesk Installer...
Plesk Installer 3.18.9 (built on 2016-03-09 15:09)
2. On the servers that aren't experiencing the issue:
/usr/local/psa/admin/bin/autoinstaller --version
Doing restart of Plesk Installer...
Plesk Installer 3.18.12 (built on 2016-10-05 12:12)

If all the C7 servers are using the same autoinstaller, why are the versions different?

I've just fixed it after strace-ing the autoinstaller execution. For some reason the broken installers had outdated files in /var/cache/parallels_installer/, after purging all that the problem went away and the remaining C7 servers are now on 12.5.30 #62.
