CentOS 7 - Converting .deb to .rpm
tl;dr:
deb 2 rpm
CentOS 7 - Converting .deb to .rpm
Sometimes there are packages which are lagging behind on certain distributions but are newer in other. Because of this it’s sometimes necessary to convert a package in order to try it out in the testing environment.

Error Summary
-------------
Rebuild the package
Because of the transaction check, we need to rebuild the package
sudo yum install -y rpmrebuild
rpmrebuild -pe snmptt-1.5~beta2-1.noarch.rpm
It will open the package settings in text editor. Go to %files% section and delete the lines that refer to the conflicting files listed above.
try to just comment the lines instead:
(Converted from a deb package by alien version 8.95.)
%files
#%dir %attr(0755, root, root) "/"
#%dir %attr(0755, root, root) "/etc/init.d"
#%dir %attr(0755, root, root) "/lib"
#%dir %attr(0755, root, root) "/usr/lib"
#%dir %attr(0755, root, root) "/usr/lib"
#%dir %attr(0755, root, root) "/usr/sbin"
Save and exit the file (exit with :wq (it’s vim)). When you exit, you will be asked if you want to continue with the rebuild. Enter Y to proceed.
rpmrebuild -pe snmptt-1.5~beta2-1.noarch.rpm
Do you want to continue ? (y/N) y
result: /root/rpmbuild/RPMS/noarch/snmptt-1.5~beta2-1.noarch.rpm
Once the rebuild is complete, you can install it properly

Complete!
Do observe though that there might still be some permission issues depending on whether the package was installed previously because of the edits in the RPM scripts.
Additional changes
As an example, this package had some more requirements that were missing after installation, and it was sorted like this:
yum install -y perl-Sys-Syslog
yum install -y perl-Net-IP.noarch
get some permissions sorted
cd /var/spool/
chown -R snmptt:snmptt snmptt/
systemctl restart snmptt
and the pids had to be sorted as well
chown snmptt:snmptt /var/run/snmptt.pid
chown snmptt:snmptt /run/snmptt.pid
After that , all that’s left was to go through the configuration file for the package and change accordingly in order to get everything up and running again. The previous configuration file was overwritten, so remember to always have a backup.
