  • 1.  DNF / Python 3.9.18 Upgrade Issue

    Posted 11/07/23 02:34 PM

    Hello Ranjit,

    I encountered the following difficulty when upgrading to dnf / python 3.9.18 from python 3.7 on our AIX server box:
    In the middle of running 'dnf update' to upgrade to python 3.9.18, we had out of space issue with /opt and I see errors like following:

    "Error unpacking rpm package python3.9-librepo-1.11.0-103.ppc

      Upgrading        : python3-librepo-1.11.0-103.ppc                                                                                                                                   70/145

    error: rpmdb: Packages: write failed for page 1738
    error: rpmdb: Packages: unable to flush page: 1738"
    We then added space to /opt and reran 'dnf update' and we always get the following error:
    "/opt/freeware/etc/dnf: dnf update
    Traceback (most recent call last):
      File "/opt/freeware/bin/dnf", line 57, in <module>
        from dnf.cli import main
      File "/opt/freeware/lib/python3.9/site-packages/dnf/__init__.py", line 25, in <module>
        import dnf.pycomp
    ModuleNotFoundError: No module named 'dnf.pycomp'    "
    I have tried to re-install the original python 3.7 dnf by running 'install-dnf.sh -d'. After removing all python3.9* packages and a couple of offending packages like python3-gpg-1.13.1-101.ppc, install_dnf ran successfully. But I then found I can't run /opt/freeware/bin/dnf, even the dnf file is there. I got following error (very weird):
    "/opt/freeware/etc/dnf: dnf update
    ksh: dnf:  not found"
    I then tried to run 'dnf_aixtoolbox_local.sh' to use local Toolbox repo for python 3.7 and got following error:
    "error: Failed dependencies:
            /opt/freeware/bin/python3_32 is needed by yum-4.2.17-32_2.noarch
            dnf = 4.2.17-32_2 is needed by yum-4.2.17-32_2.noarch
            dnf-data = 4.2.17-32_2 is needed by yum-4.2.17-32_2.noarch
            yum >= 4.2.17-32_1 is obsoleted by (installed) dnf-4.2.17-32_50.ppc"
    Please help.
    Thanks

    Hi

     Are you trying to install python 3.7 from your locally hosted AIX repo ?

    How this local repo is configured ? is it the same system where you are installing python3.7 or different system acts as repo system ?

    what's the current installed dnf version ?  output of 'rpm -qa | grep -I dnf' ?

    Thanks

    Ranjit

    Hi Ranjit,

    Please see my answers below:

    1.  Are you trying to install python 3.7 from your locally hosted AIX repo? - Actually I has tried to re-install python 3.7 and old dnf by running 'install_dnf.sh -d'. Although the running is successful, I can't run dnf (system says not such file, even through the file is there. So I tried to config it with local repo by running "...//ezinstall/ppc/dnf_aixtoolbox_local.sh".

      /opt/freeware/bin: ls -lrt /opt/freeware/bin/dnf-3
      -rwxr-xr-x    1 root     system         1960 Apr 28 2023  /opt/freeware/bin/dnf-3
      /opt/freeware/bin: /opt/freeware/bin/dnf-3
      ksh: /opt/freeware/bin/dnf-3:  not found

    2. How this local repo is configured ? is it the same system where you are installing python3.7 or different system acts as repo system ?
      It's on the same AIX box where python3.7 is insatlled. I downloaded the iso file and extracted it by running "gzip -dc ESD-Toolbox_for_Linux_Apps_Common_7.1-7.3_122022_LKT010325.tar.gz | tar xf - -C {destination folder}"

    3. what's the current installed dnf version ?  output of 'rpm -qa | grep -I dnf' ?
      Based on the following output, I think the dnf is still the upgraded one, which means the effort to re-install the old dnf associated with python 3.7 wasn't successful:
       /opt/freeware/bin: rpm -qa | grep -i dnf
      dnf-automatic-4.2.17-32_50.ppc
      dnf-data-4.2.17-32_51.ppc
      python3-libdnf-0.39.1-32_52.ppc
      libdnf-0.39.1-32_52.ppc
      python3-dnf-4.2.17-32_51.ppc
      Please provide method to resolve the issue. Thanks in advance.

    Mi

    Hi Mi,

    I think you need to clear your installed old dnf and it's dependent packages.

    You can run this command to remove those rpms and then run the dnf script again.

    rpm -e libcomps python3-libcomps python3-dnf dnf dnf-automatic dnf-data libdnf python3-hawkey python3-libdnf librepo python3-librepo
