rpm: /lib64/liblzma.so.5: version `XZ_5.1.2alpha' not found (required by /lib/librpmio.so.3)

Question

I am stuck with this error. Not able to install any RPMs. Please help

OS is RHEL6.9 64 bit

Thanks in advance.

Answer 1

This happens when you download and install xz from sources on a RHEL (or CentOS) 7 system. The problem is that the XZ_5.1.2alpha label is not present in the released versions of xz, but it is present in the version RedHat ships and compiles against.

A small patch to the xz sources will fix the problem:

https://github.com/easybuilders/easybuild-easyconfigs/issues/4036

The patch is small enough to copy&paste here. I have used it on xz-5.2.4 successfully.

(update)

If you try to use this .so on CentOS 8, you will get unresolved symbols for XZ_5.2 (e.g. librpmio.so.8 wants lzma_stream_encoder_mt@XZ_5.2).

Here is a revised patch to create an liblzma.so.5 library that will work on both CentOS 7 and 8:

Answer 2

I was stuck with similar problem since Nov 27, 2017 when I installed XZ Utils 5.2.3 from sources on CentOS 7.4 and copied liblzma.so.5.2.3 from /usr/local/lib/ to /lib64/.

Cause of this problem is library librpmio.so.3 which requires symbol XZ_5.1.2alpha to be defined in lzma shared library. liblzma.so.5.2.2 defines this symbol but liblzma.so.5.2.3 doesn't.

Without XZ update the most recent version of lzma library was 5.2.2 and I had symbolic link /lib64/liblzma.so.5 -> /lib64/liblzma.so.5.2.2. After copying liblzma.so.5.2.3 and some further updates the link was changed to the most recent file i.e. /lib64/liblzma.so.5 -> /lib64/liblzma.so.5.2.3. And that broke rpm and yum commands. So, solution is:

1. Link /lib64/liblzma.so.5 back to /lib64/liblzma.so.5.2.2:

   cd /lib64
   sudo ln -s -f liblzma.so.5.2.2 liblzma.so.5
   

2. Delete file /lib64/liblzma.so.5.2.3

Second possible cause might be environment variable LD_LIBRARY_PATH. Check if it contains unwanted paths and clear it.
