Is it possible to disable new version checking in pgAdmin 4?
Add this line to config_local.py and restart the pgadmin4:

UPGRADE_CHECK_ENABLED=False


Note:
The location of config_local.py is same as config.py. You can find the location of config.py with this command in linux:

$ find / -wholename "*/web/config.py" 2&gt;/dev/null


If the config_local.py file doesn't exist yet, you can create one.
