'LVMVolumeGroupDevice' object has no attribute 'vg'

Hello

I cannot install any Red Hat products on my laptop, this includes Fedora, Centos, Almalinux, and RHEL. My method for recovering an installation is to reinstall from an Fedora ISO but I receive the following error when I boot into Anaconda:

dasbus.error.DBusError: ‘LVMVolumeGroupDevices’ object has no attribute ‘vg’

I also receive an error when trying to open blivet-gui:
AttributeError: ‘LVMVolumeGroupDevice’ object has no attribute ‘vg’

Here are the list of the logical volumes and volume groups on my computer

I deleted to encrypted logical volules, then deleted the lines from the /etc/crypttab file. Any suggestions?

Thank you

Hello
Issue resolved. There was an issue with a snapshot I created, 20220821-preMBPT. I reviewed the storage.log from the anaconda error report. Followed this message:

I deleted the snapshot, blivent and Anaconda are now working.

I hope this helps someone in the future.

I marked your last post as solution so that others know at first glance that the topic is solved with that. Feel free to change that if anything is wrong with it.

Thanks for documenting your solution for others!
