RPM install file conflict from previous install

Question

I am getting install failure due to file conflicts. I am facing this issue only on Red Hat Linux 7. Same spec file works on Ubuntu and other Linux distributions.

I tried putting echo on %pre, %post, %preun and %postun sections but I never reached those messages. I tried %dump at the beginning of spec file which also didn't print anything. How do I trace the spec file execution?

%files
%defattr(-,root,root,-)
@CPACK_PACKAGING_INSTALL_PREFIX@/sbin/MyExe
@CPACK_PACKAGING_INSTALL_PREFIX@/share/doc/@CPACK_PACKAGE_FILE_NAME@/myconf.conf
@CPACK_PACKAGING_INSTALL_PREFIX@/share/doc/@CPACK_PACKAGE_FILE_NAME@/README
%if @IS_RHEL7@
/etc/systemd/system/myoverride.conf
%endif

Error during install:

Preparing packages...
    file /etc/systemd/system/myoverride.conf from install of mypackage-5.0.1.x86_64 conflicts with file from package mypackage-4.11.1.x86_64
    file /usr/sbin/myexe from install of mypackage-5.0.1.x86_64 conflicts with file from package mypackage-4.11.1.x86_64

Solution

you cannot install twice the same rpm. Therefore if you want to install a newer version of the same rpm (mypackage in your case); you need to use the -U | --upgrade option. Typical usage of rpm goes like this:

rpm -Uvh mypackage-<new-version>.rpm

• -U : upgrade mypackage to this version
• -vh : nice display of progress.

What method of installation are you using? I mean rpm or yum?

[Admin]

I am using rpm, I do not want to use -U option for upgrade or --force or --replaceFiles etc. I want it to handle the upgrade itself.

Both rpms have different version of the config and installer, they include changes in configuration file and exe. I need to upgrade both with this install.

If you want to install both rpms you'll need to rename one of them because you cannot install two rpms with the same name
