I have installed a mailman3 server following this documentation: https://docs.mailman3.org/en/latest/install/virtualenv.html#virtualenv-insta...
After a few hiccups I got mailman and postorius working and migrated one list according to this documentation: https://docs.mailman3.org/en/latest/migration.html
It seemed to work and also hyperkitty_import was run without errors (or at least none shown up). Running update_index command said that there were 0 threads copied but I kjnow that the archive isn't empty. But now when I tried to open the list info page from lists view it dies with 500 error.
After diving into the different log files I found an error message that it cannot find /etc/mailman3/mailman-hyperkitty.cfg. Great. Only that the cfg file exists and seems to my (unexpert) eyes correct.
After that problem I tried to create a new list. Creation seemed to go all right but also with it, trying to open the list info page it shows 500 error.
When googling for a solution I landed on a message stating that there might be double entries for the same list in listarchiver table but when I checked ot turns out that the table is empty!
I am a bit confused how to figure out the base cause of the problem and would very much appreciate any pointers.
