What's wrong with yum in F19?

[Cristian Sava]

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?

Thanks,
C. Sava

Since it's within Yum history, have you tried "yum history new" yet?

Tried now with no luck.
Anything else?
That install is no big deal for me. I'm just curious how it can be
fixed.

Try:

rm -rf /var/lib/yum/*  ; yum history new

More interesting would be to figure out how you have managed to run
into this situation and whether it is a bug.
