Hello!
I tried to upgrade Pixelfed to the new version today but I have the following error:

Should I do anything from my side?
Thanks for your help!

I tried a second time but I still have the same problem. Do other Pixelfed admins are facing the same situation?

It’s not related to pixelfed per se, but to the postfix conf

Can you share what happens when you run sudo postmap /etc/postfix/app_senders_login_maps ?

[jarod5001]

What yunohost version do you have?
Anything interesting in the diagnosis?

Thanks for the suggestion, I run your command, I had this result:

root@hhh: /etc/postfix# sudo postmap app_senders_login_maps
BDB0002 __fop_file_setup: Retry limit (100) exceeded
postmap: fatal: open database app_senders_login_maps.db: File exists

So I had to delete the existing file (0 bytes) and rerun your command, and then I could finally upgrade Pixelfed. Thanks for your help!
