I tried to install yaml manually. But it seems there is no plesk-py27-pyyaml package on the yum server.

Hi Smashing,

we can see from your informations, that you use a CentOS/RHEL - based operating system, but unfortunately, you don't mention which one?!? And even that you placed the thread in "Plesk 12.x for Linux", we can not guess, which Plesk version you have.

Your question:
Can I install yaml manually?
Can certainly be answered with a "yes", but without your operating system informations, we are not able to guide you to the path, which suits your environment, or with the exact command to use. We can only suggest to use a mirror site, so that you are able to navigate to the correct URL by yourself:

ftp://ftp.hosteurope.de/mirror/autoinstall.plesk.com/PMM_0.1.10/​



For CentOS 7 ( x86_64 ) for example, you would use the commands:

Code:
mkdir -p /root/plesk/downloads
cd /root/plesk/downloads
wget http://autoinstall.plesk.com/PMM_0.1.10/dist-rpm-CentOS-7-x86_64/packages/plesk-py27-pyyaml-3.11-centos7.15082413.x86_64.rpm
rpm -Uvh plesk-py27-pyyaml-3.11-centos7.15082413.x86_64.rpm


... but ( !!! ), with the provided resolution from your mentioned KB - article ( 129990 ), you should definetly reach the very same result, or use the commands:

Uninstall/Remove:
/usr/local/psa/admin/bin/autoinstaller --select-product-id plesk --select-release-current --remove-component pmm

Install:

/usr/local/psa/admin/bin/autoinstaller --select-product-id plesk --select-release-current --install-component pmm
 
Hello Smashing,

This issue was fixed in the latest release of Plesk Migrator 2.1.8 that was released yesterday. Try to remove and install Plesk Migrator again using Extension catalog.
