[Pulp-list] pulp-2to3-migration plan create Server Error 500

Thu May 13 03:20:23 UTC 2021

Hello pulp-list,

I was able to migrate my pulp2 iso repos using pulp-2to3-migration, but 
now that I try to do the same with my rpm repos, I get the following:

[root at honeybee ~]# pulp migration plan create --plan='{"plugins": 
[{"type": "rpm"}]}'
Error: <h1>Server Error (500)</h1>
[root at honeybee ~]#

In between the successful and the failed migration, I have upgraded pulp 
to 3.12.2.

[root at honeybee ~]# pulp status
{
   "versions": [
     {
       "component": "core",
       "version": "3.12.2"
     },
     {
       "component": "pulp_2to3_migration",
       "version": "0.11.0"
     },
     {
       "component": "rpm",
       "version": "3.10.0"
     },
     {
       "component": "python",
       "version": "3.2.0"
     },
     {
       "component": "file",
       "version": "1.7.0"
     },
     {
       "component": "deb",
       "version": "2.11.1"
     },
     {
       "component": "container",
       "version": "2.5.1"
     },
     {
       "component": "ansible",
       "version": "0.7.2"
     }
   ],

I looked at the system log (attached) and I found that it failed to 
initialise the database connection. How can I diagnose/repair this problem?

Thanks,
Ben Stanley.
