downgrade postgis 2.4.3 to 2.4.1

Hi list

I have recently upgraded my PostGIS 2.4.1 to 2.4.3, which introduced a
problem caused by one of the dependencies (geos 3.5.0 -> 3.6.2).

Now I would like to do a yum history undo to return my system to its
previous state, but when invoking yum history undo on that particular
transaction id, I get the following messages:

Failed to downgrade: postgis24_10-2.4.1-1.rhel7.x86_64

Failed to downgrade: postgis24_10-client-2.4.1-1.rhel7.x86_64

Failed to downgrade: postgis24_10-devel-2.4.1-1.rhel7.x86_64

Failed to downgrade: postgis24_10-utils-2.4.1-1.rhel7.x86_64

Failed to downgrade: postgis24_96-2.4.1-1.rhel7.x86_64

Failed to downgrade: postgis24_96-client-2.4.1-1.rhel7.x86_64

I guess this is because the packages in question doesn’t exists in the repo
anymore.

Is there any way to get access to these packages again?

PS I’m running Red Hat 7.4

Regards,

Jonas
