No names found running the script

[Sforg26]

Hello! Thanks for your work

Sorry it's probably a newbie question, I don't have any experience at all in building from source, but I really need this tools for my everyday work.

I have initialized git in the folder, but when I try to run the script (both debian and fedora) it gave me the follwing error:

[user@disp9487 qubes-video-companion-master]$ DEBUG=1 ./build/create-rpm.sh
+ set -E
+ set -euo pipefail
+ trap exit ERR
+ package_type=vm
+ case $package_type in
+ :
+ case $0 in
+ local_dir=././build
+ cd ././build
+ pwd
/home/user/QubesIncoming/work/qubes-video-companion-master/build

gpg:              unchanged: 1
+ cd ..
++ git describe --abbrev=0
fatal: No names found, cannot describe anything.
+++ exit
+ version_tag=
++ exit

Which is the name that it need to find?
Any helps will be appreciated
Thanks in advance
