Autoinstaller Error

[comicmaus]

Hi,
I have a pre-configured system with Plesk 12.5 on Centos 7 (german version).
Whenever I try to change any components via the autoinstaller at the commandline, I can walk through all steps , but get the same error at the end. No matter if I try to install or uninstall packages or if I do only one thing or multiple tasks at the same time, it always quits with this error. Looks like the error is not related to a special package, it occurs when installing php, qmail or anything elese ...

Maybe anybody had a similar problem can help me solving it?

Can you install something with yum in CLI? For example, do you have any error messages if you try to install mc with

# yum install mc

?

Yes, normal installation or update with yum works correctly.

After three days of searching I probably found the reason:
The \xf6 ASCII code is a german special character (Ö) and it looks like python 2 has some problems with decoding.
If you work with a german OS version the locale settings are usually de_DE.utf8. So can workaround the problem by setting the locale to C for instance.
With this configuration there are no special characters to decode and so there will be no error

In CentOS 7 this can be done by changing the entries in /etc/profile, /etc/sysconfig/i18n or creating an own .i18n file in your home directory.
