After upgrading from Kubuntu 18.04 to 20.04 I have no sound in Cantata. When I hit the play button, the progress bar is not advancing.
mpd's log file at /var/log/mpd/mpd.log shows:
ALSA lib pcm_dmix.c:1089:(snd_pcm_dmix_open) unable to open slave
exception: Failed to open "My ALSA Device" (alsa)
exception: nested: Failed to open ALSA device "default": No such file or directory
When starting pgAdmin, I'm prompted:
Please set a master password for pgAdmin
This is a new feature of pgAdmin4 4.7: https://www.pgadmin.org/docs/pgadmin4/dev/release_notes_4_7.html
How can I disable this?
The local documentation tells me to set the "configuration parameter" MASTER_PASSWORD_REQUIRED=False, but I don't know where/how to do this:
http://127.0.0.1:37059/help/help/master_password.html
When I save or load a query in pgAdmin4 3.4, the file dialog shows just an empty directory named /. I can create folders inside it and I can save the query inside it. But I have no idea where this folder is actually located in my filesystem.
I'm getting this error on startup of pgAdmin4 on Kubuntu 18.04:
An error occurred initialising the application server:
Failed to launch the application server, server thread exiting.
In the following window ("Configuration") I have these default values:
Python Path:
/usr/pgadmin4/lib/python2.7;/usr/pgadmin4/lib/python2.7/site-packages
Application Path:
/usr/pgadmin4/web
Since I don't have a /usr/pgadmin4/ directory, all of them are wrong.
