Challenge

When installing Veeam Agent for Linux on Oracle Linux with UEK kernel, the veeamsnap package fails to install with the following error:

Error! Bad return status for module build on kernel: <kernel version>
Consult /var/lib/dkms/veeamsnap/<Veeam Agent for Linux version>/build/make.log for more information.

 

The make.log (example below) will display an error stack referencing libdtrace-ctf.so.1 and LIBDTRACE_CTF:
/var/lib/dkms/veeamsnap/<Veeam Agent for Linux version>/build/make.log

scripts/dwarf2ctf/dwarf2ctf: /usr/lib64/libdtrace-ctf.so.1: version `LIBDTRACE_CTF_1.3' not found (required by scripts/dwarf2ctf/dwarf2ctf)
make[1]: *** [/var/lib/dkms/veeamsnap/_<Veeam Agent for Linux version>_/build/.ctf/build-extmod.stamp] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [modules] Error 2
make: Leaving directory `/usr/src/kernels/<kernel version>'

Cause

This issue occurs because libdtrace-ctf, which is required to build the veeamsnap module,  is not installed.

libdtrace-ctf is a dependency of the UEK kernel headers, so normally it should be present if kernel headers are also installed. You can check using this command:

yum deplist kernel-uek-devel

Example output

<...>
dependency: libdtrace-ctf >= 1.1.0
provider: libdtrace-ctf.x86_64 1.1.0-2.el7

 

In some cases, due to package manager or other issues, libdtrace-ctf may not be pulled properly, resulting in the kernel headers be installed but missing libdtrace-ctf.

Solution

Install libdtrace-ctf manually:
yum install libdtrace-ctf

After the libdtrace-ctf package is installed, uninstall and reinstall (onlineoffline) Veeam Agent for Linux.

 

Note: If the Oracle Linux machine does not have internet access to install packages, locate the libdtrace-ctf package for your Oracle Linux version on the Oracle Linux repository and install it manually: https://yum.oracle.com
