Thread: pgadmin4 client can't start server

Hi,

The current version 4.11 and 4.x before does not start the server on Ubuntu.

When starting pgadmin4 in a terminal window "pgadmin4" three splash screens open with  "Starting pgAdmin4 server...", "Taking longer than usual...', 'Almost there..." and then "The Application server could not be contacted".

"pgadmin -h" or "pgadmin --help" did not help (options just ignored), "man pgadmin4" is a  "no info".

And i can't find any log files to see what's going on.

regards

wambacher

IIRC pgAdmin3 was ok.

I had the same problem.  Just installed the .deb and I'm running on
buster and I accidentally was using the stretch repository.

I updated to the buster pgadmin4 repo and now it's loading.

Make sure your distro matches the package.

Hi,

Could you please share log files having name like - .pgadmin.startup and .pgadmin.<number>. You'll find these files in your user home directory.

trying my best:

Startup:

wambacher@server2:~$ pgadmin4
Python path:  "/usr/lib/python3/dist-packages"
Python Home:  ""
Webapp path:  "/usr/share/pgadmin4/web/pgAdmin4.py"
NOTE: Configuring authentication for DESKTOP mode.
wambacher@server2:~$

/home/wambacher/.pgadmin/pgadmin4.log   is empty

sessions and storage too.

pgadmin4.db is containing data

I had the same problem.  Just installed the .deb and I'm running on buster and I accidentally was using the stretch repository.

I updated to the buster pgadmin4 repo and now it's loading.

Make sure your distro matches the package.

Running Ubuntu 19.4 and installed using packet manager. Got version 4.11-1.pgdg18.04+1

is there a better repo availiable?

Hi,

I would suggest removing the ".pgadmin" directory from user home directory and try again. Other things looks fine.

That was the first i did. And then i told you the results.
