rear/rear

Hello Everyone, I installed rear on the following linux server:

Distributor ID: Ubuntu
Description: Ubuntu 14.04.5 LTS
Release: 14.04
Codename: trusty

I DOWNLOADED THE BITS FROM THE FOLLOWING LOCATION:
sudo wget http://download.opensuse.org/repositories/Archiving:/Backup:/Rear/xUbuntu_14.04/rear_2.2.orig.tar.gz

UNTAR:
sudo tar xzvf rear_2.2.orig.tar.gz

LASTLY BUILT AND INSTALLED IT:
sudo make install
== Validating scripts and configuration ==
find etc/ usr/share/rear/conf/ -name '.conf' | xargs -n 1 bash -n
bash -n usr/sbin/rear
find . -name '.sh' | xargs -n 1 bash -n
find usr/share/rear -name '.sh' | grep -v -E '(lib|skel|conf)' | while read FILE ; do \
num=$(echo ${FILE##/} | cut -c1-3); \
if [[ "$num" = "000" || "$num" = "999" ]] ; then \
echo "ERROR: script $FILE may not start with $num"; \
exit 1; \
else \
if $( grep '[_[:alpha:]]' <<< $num >/dev/null 2>&1 ) ; then \
echo "ERROR: script $FILE must start with 3 digits"; \
exit 1; \
fi; \
fi; \
done

VERIFIED THE VERSION:
rear --version
Relax-and-Recover 2.2 / 2017-07-20

MY ISSUE IS THAT WHEN I EXECUTE A rear dump command i get the following error:
sudo rear dump
Relax-and-Recover 2.2 / 2017-07-20
Using log file: /var/log/rear/rear-gitlab.log.lockless
ERROR: EFI_STUB="" is incorrect option value pair.
Aborting due to an error, check /var/log/rear/rear-gitlab.log.lockless for details

AND THE LOG FILE DOESN'T SHOW MUCH AS YOU CAN SEE:
sudo cat /var/log/rear/rear-gitlab.log.lockless
