ModuleNotFoundError: No module named 'nbd' in Fedora 43

[egosgt]

Hello. First of all, thank you for the work you do creating and maintaining what promises to be a very neat utility (specially for those of us new(ish) users to Linux who run VMs and want to back them up). Unfortunately I'm getting the following error:

File "/usr/bin/virtnbdbackup", line 27, in
from nbd import version as nbdversion
ModuleNotFoundError: No module named 'nbd'

I'm using Fedora 43 and used the .rpm for Fedora 42 as that was the highest available package version closest to my distro version. I saw older conversations where it's stated the .rpm is specific to a distro version and unlikely to be compatible with a newer version. Which seems to be the case for me.

Anyways, if you happen to know of a way how I can overcome the nbd module problem in Fedora 43 please let me know! Fedora 44 is scheduled to come out late April 2026.

the fedora 4.2 packages are not compatible to fedora 4.3

i have added both fedora 4.3 and fedora 4.4 packages to the build process. Latest build packages can be downloaded
here:

(see Artifacts)

the zip package includes rpm s specific for fedora 4.3/4.4

yum install virtnbdbackup-2.45-1.noarch.fedora43.rpm

That's amazing, thank you very much! I uninstalled the old (wrong) rpm for Fedora 42 and downloaded and installed the rpm for Fedora 43. I'm finally able to issue a basic command like "sudo virtnbdbackup --version" without it giving me errors.

Much appreciated!
