biber > 1.9 dies (?) with error 255 about biber HOT 11 CLOSED

The crucial line is:

WARN - Warning: Found biblatex control file version 2.5, expected version 2.6

You are using a version of biblatex incompatible with biber 1.9+ (probably version 2.8)

from biber.

Ok, in that case I recommend Fedora 20 users get [http://copr.fedoraproject.org/coprs/cbm/biber-1.8] until texlive-biblatex is bumped.

I have somewhat similar error in Fedora 21 workstation 64 bit. I have TeX Live 2014 from standard/updates repositories and biber from https://copr.fedoraproject.org/coprs/cbm/Biber/
I think another key message is:
INFO - This is Biber 2.0 (beta)
which I get too.
Additionally,

    biber -v

outputs:

    biber version: 2.0 (beta)

Shouldn't it be 1.9 instead of 2.0 (beta)? Because the standard pdflatex I have installed writes a .bcf in format version 2.5 and that can be understood by biber 1.9. On the other hand, biber 2.0 expects a .bcf in format version 2.6 which is not there.
So, long story short: we probably need something like
http://copr.fedoraproject.org/coprs/cbm/biber-1.9
for Fedora 21.
But

yum info biber

produces

            : biblatex, which provides a powerful and flexible macro interface for
            : authors of citation styles.

which makes me think of a packaging bug in /coprs/cbm/biber, but I am new to Fedora, so I am not sure.

@espinozahg, you can use this for now: https://copr.fedoraproject.org/coprs/cbm/f21-biber-1.8

from biber.

thanks @cbm755 . I tried f21-biber-1.8 now and works correctly.

@cbm755 :
After installation cbm/f21-biber-1.8 worked without any warning as I mentioned before, but now It is not working properly (after reboot and clean environment in terminal). I haven't had the time to see what is going on. I switched to cbm/Biber which outputs lots of warnings (perl related and biber/biblatex version compatibility related) but produces a visually OK pdf file with pdflatex.

Hmmm could you get us an error msg?

from biber.

I uninstalled biber, disabled cbm/Biber, enabled cbm/f21-biber-1.8, installed biber again and rebooted just in case but I cannot reproduce the error I got before with cbm/f21-biber-1.8
I could post the errors/warnings with cbm/Biber but I don't think they are needed, are they?
I will continue using cbm/f21-biber-1.8 and report if any error/warning appears again.

I'm back again. I have one file set that doesn't work with biber from cbm/f21-biber-1.8 . The file set has one .bcf file and one .bib file
Executing
biber thesis
I get no error or warning (either on screen or on the .blg file), but the .bbl file is 0 bytes.
I've tried biber with the following options to see what is going on, but still, no error or warning, biber just dies with exit code 1 (echo $?). The options are: --nodieonerror --decodecharsset=full --trace
The files are:
https://sites.google.com/site/espinozahg/stuff/aux-references.bib?attredirects=0&d=1
https://sites.google.com/site/espinozahg/stuff/thesis.bcf?attredirects=0&d=1
I have to mention that this .bib file works with TeX Live 2014 under Ubuntu 12.04. The .bcf file is a newer version there.

Perhaps you should file a new issue? When you do, you'd better clearly state biber versions used on each system. Also, narrow down to a minimal nonworking example.
