Bonjour

j'ai un probleme que je ne sais pas résoudre

quand je fais apt-get install xlibmesa-gl
j'obtiens :
Reading Package Lists...
Building Dependency Tree...
Suggested packages:
xlibmesa-dri
The following NEW packages will be installed:
xlibmesa-gl
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.
Need to get 0B/283kB of archives.
After unpacking 762kB of additional disk space will be used.
(Reading database ... 9418 files and directories currently installed.)
Unpacking xlibmesa-gl (from .../xlibmesa-gl_4.3.0.dfsg.1-14sarge1_i386.deb) ...
dpkg: error processing /var/cache/apt/archives/xlibmesa-gl_4.3.0.dfsg.1-14sarge1_i386.deb (--unpack):
unable to create `./usr/X11R6/lib/libGL.so.1.2': No such file or directory
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
/var/cache/apt/archives/xlibmesa-gl_4.3.0.dfsg.1-14sarge1_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

J'ai essayéun apt-get -f, un upgrade, un update et j'ai constaté que libGL.so.1.2 existe déjà dans /usr/X11R6/lib/libGL.so.1.2

que faire SVP
