I have Tech support with Acronis but they are passing the buck.
Tech told me:
As far as I understand, the current problem is that installation of Acronis Backup and Recovery 11.5 Server for Linux fails with “Failed to find directory ‘/lib/modules/220.127.116.11-0.3-default/build’ with the kernel sources”
The issue is that the setup program cannot find kernel source files in the /lib/modules/<MY_KERNEL>/build or in the /lib/modules/<MY_KERNEL>/source directory.
Installing kernel source varies with every distributor of Linux.
In case of Debian and Ubuntu, the command is like the following.
$ sudo apt-get update
$ sudo apt-get install linux-headers-
$ sudo apt-get install linux-image-
You may need to contact Suse Linux - https://www.suse.com/ if you are not familiar with this.
Please install the product after installing kernel source and let me know if the issue is resolved.
Does someone know what I need to do - I really need a backup.
I would really appreciate some help if you know of a solution.
