My installation has newer versions. I have

(/usr/local/texlive/2010/texmf-dist/tex/latex/biblatex/biblatex.sty
Package: biblatex 2011/05/12 v1.4c programmable bibliographies

(/usr/local/texlive/2010/texmf-dist/tex/latex/etoolbox/etoolbox.sty
Package: etoolbox 2011/01/03 v2.1 e-TeX tools for LaTeX

where you have

(/usr/local/texlive/2010/texmf-dist/tex/latex/biblatex/biblatex.sty
Package: biblatex 2010/03/19 v0.9a programmable bibliographies

(/usr/local/texlive/2010/texmf-dist/tex/latex/etoolbox/etoolbox.sty
Package: etoolbox 2010/04/10 v1.9 e-TeX tools for LaTeX

You might try to reinstall, or force install, the biblatex package (and maybe the etoolbox package), using tlmgr.

thanks
so the problem is just old version
the tlmgr is frozen , do you know how can i make the forcing for the update in this case?
also do you know when the new version of the texlive 2011 will appear?

No, I don't know the release schedule for TeXLive. But I think your problem isn't that TeXLive is frozen, but that for some reason your tlmgr isn't getting you the most recent version -- if I could get it, you should be able to as well. Read in the tlmgr doc for how to install/reinstall/force reinstall.

Try this:
`sudo tlmgr install --reinstall biblatex`

i found the following error

tlmgr: package repository /mnt/texlive2010
Cannot load TeX Live database from /mnt/texlive2010 at /usr/local/texlive/2010/bin/x86_64-linux/tlmgr line 4277.

Don't think I can help. That looks like something about your installation of TeXLive -- tlmgr can't find the database on your system? Maybe look into TeX Live docs and support

http://www.tug.org/texlive/tlmgr.html

Good luck!

Hello
i sent mail to the texlive mailing list and they told me about the solution for the the strange error that make me unable to make update .
they told me those two solution and it works.
You should either:

1. Mount the TeX Live 2010 DVD (or and iso image of it) at /mnt/texlive2010

or

2. Switch the online repository using "tlmgr option repository ctan". Be warned,
however, that this will install the current version of biblatex, probably not
the same as the DVD version. Also, this will stop working in a few days when TL
2011 will be published, this the repo will work with TL 2011 only.

regards
