Hi all,

I have a virtual install of F19 x64 and I want to update:

yum update

sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you
use a text_factory that can interpret 8-bit bytestrings (like
text_factory = str). It is highly recommended that you instead just
switch your application to Unicode strings.

I tried to fix this but "yum clean all", "rpmdb --initdb", "rpmdb
--rebuilddb" does not help.
Trying to update individual packages work for some, fail for others.
I can't update rpm, yum, python and others.

Any advice how to fix this?
