What happened to Postman?!
(programming.dev)
Unfortunately I have no idea why your updates have stopped working.
As for having to run the upgrade command, have you considered using cronie
to run the command on a schedule for you?
Here's a decent guide for it if you wanted to look into it as a bandaid fix.
I think I remember insomnia being a pretty popular alternative when I first picked up Postman. Never gave it a chance but maybe now it's the time to switch.
