Question regarding Lab 10.2 (best way to revert back to rpm_BACKUP)

edited December 2022 in LFS207 Class Forum

Hello Instructors/Mentors,

(I am running openSUSE Tumbleweed on a VM)

As a note I would like to mention that 'rpm' on openSUSE system is located on (symbolic linked) '/usr/lib/sysimage/'

The questions I have is:

  • What is the best way to revert back to 'rpm_BACKUP' in case (new) rpm doesn't function properly after '--rebuilddb'? I have tried 'sudo cp' and 'sudo mv' command to replace new 'rpm' with 'rpm_BACKUP' however when I lookup the number of files (using 'ls -l rpm rpm_BACKUP') afterwards they still differ as if replacing (using cp and mv) command didn't work.
  • (Not sure if it's the right question to ask however here it goes) Is 'rpm --rebuilddb' performs comparable action as 'apt update && apt upgrade' performs in ubuntu even though one is low-level and the other is high-level utility respectively?

(Screenshot attached for reference)

Please provide clarification.

Thank you,
Amar

    I don't have access to a Tumbleweed, but on OpenSUSE Leap 15.4, please note that

    1. student@localhost:/var/lib/rpm> ls -li /var/lib/rpm /usr/lib/sysimage/rpm
    2. 131077 lrwxrwxrwx 1 root root   26 Nov  3 04:50 /var/lib/rpm -> ../../usr/lib/sysimage/rpm

    so it is /var/lb/rpm. The link is irrelevant. The layout of these files is quite different between redhat-based systems
    and SUSE, but the functionality of rpm --rebuilddb should not be different. I'm not sure what problem you are pointing to. Did you do a diff sinstead of a ls -l? Meta data can change without any meaning to it

    Note that so few students use SuSe-based platforms that it has been a while since we have checked this lab on openSuse but it worked as of last attempt.

    and on opensuse this directory looks nothing like Tumbleweed so I cannot help you :smile:
