as per subject I'm working on a SLESS 11 for VMware machine which has been upgraded from SLES11 SP1 to SLES 11 SP3, as I ws not the one who performed the upgrade I'm not sure what or how it has been performed.

The server is running kernel version 3.0.101-0.8-default which I would need to upgrade to 3.0.101-0.31-default and on top of this I see there are couple of more updates to installed Software that need be updated, when I issue a zypper update command I get the following :

What I cannot understand is why SUSE Linux Enterprise Server 11 SP1 for VMware is in there, in all the other SP3 machines that I've personally upgraded this never came up so I'm a bit puzzled, what also I cannot understand is the last message The following packages are not supported by their vendor: what does that mean? I'm more of a RH guy and in many years never seen such a message so I'm double puzzled :-)

If I proceed with the update it seems to run smoothly but at the end of it if I try to run zypper update (or lr) or many other commands I cnanot recall at the moment I get the following:

 zypper update
zypper: /lib64/libz.so.1: no version information available (required by /usr/lib64/libxml2.so.2)
zypper: /lib64/libz.so.1: no version information available (required by /usr/lib64/libxml2.so.2)
zypper: /lib64/liblzma.so.5: no version information available (required by /usr/lib64/libxml2.so.2)
zypper: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /usr/lib64/libxml2.so.2)
zypper: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by /usr/lib64/libxml2.so.2)
Message per se is pretty clear but I confirmed all required libraries/files are indeed where they should be, I've also tried to manually update these files to the latest available release but problem is exactly the same.

Honestly I ran out of ideas and find myself stuck with this system that needs updates but cannot deploy them, does anyone have an idea what the issue could be or what I could do?

Thanks in advance for any help which would highly appreciated
