[SOLVED] rpmUtils.miscutils in python3.6

Issue

I am refactoring code from python2(RHEL 7.6) to python3(RHEL 8.2) and I have problem with missing library in python3.6.

Problem:

from rpmUtils.miscutils import splitFilename ModuleNotFoundError: No module named 'rpmUtils'

I've tried to install python3-dnf and python3-rpm packages to RHEL8, but still not working. Is there any solution how to use this library in python3.6 and RHEL8 or should I write some custom function by myself?

Thank you for your answer.

Solution

This library was indeed removed, but you have several other options you can use.

Please note that these other functions expect to receive a string in the NEVRA (name, epoch, version, release, architecture) format as an input, not a filename. Thus you must remove the '.rpm' extension of the filename, in order to get a NVRA string (epoch normally is not included in the filename of the RPM package).

So basically you have 2 options:

• to use dnf as suggested in i.e. https://bugzilla.redhat.com/show_bug.cgi?id=1364504

• to use hawkey i.e. :

    import hawkey
  
    rpm_base_filename = os.path.basename(rpm_file)
    nevra = hawkey.split_nevra(rpm_base_filename[:-len(".rpm")])
    name = nevra.name
    version = nevra.version
    release = str(nevra.release)
    epoch = str(nevra.epoch)
    arch = nevra.arch
  

For example here is a patch for such modification that I made for one of the tools we use as part of the oVirt release process:
