Questions[installed-programs](ubuntu)

I often use drawing application.

Since a few days the app doesn't start. I have Ubuntu 22. I tried to uninstall and re-install the app via snap, but, even after that, nothing happens when I start the app. Here is my terminal output.

user@user-All-Series:~$ sudo snap install drawing
[sudo] password di user: 
drawing 1.0.1 da Ken VanDine è stato installato
user@user-All-Series:~$ drawing &
[1] 212365
user@user-All-Series:~$ /snap/drawing/27/gnome-platform/command-chain/desktop-launch: /snap/drawing/27/usr/bin/drawing: /snap/gnome-42-2204-sdk/current/usr/bin/python3: bad interpreter: No such file or directory
/snap/drawing/27/gnome-platform/command-chain/desktop-launch: line 603: /snap/drawing/27/usr/bin/drawing: Success

Any help is appreciated. Thank you, Andrea

When I boot up my Ubuntu 20.02 laptop, MT (Microsoft Teams) always starts. Since I would like to avoid this, I went to the default program "Startup Applications" and removed the tick for MT.

Though this works for two or three boots, afterwards, I am still stuck with the same problem. Interestingly, the tick for MT in Startup Applications is still there, even though I removed MT from the list.

Help would be appreciated!

I want to add a custom program to the favourites of Ubuntu dock, but there is no option for that.

Translating the text in this image (same as above) only says:

1. All windows

2. Quit

It also doesn't appear in "Show Applications":

Is there a way for adding the program to both Favourites and Applications menus?

how to reset a program to its default state?

in android we can clear application data to reset the application to its default state. does it is possible to reset a program in ubuntu to its default state without uninstalling and reinstalling.

How can I check which applications are using internet? How to block internet accessing one particular application? Is there any GUI tool that exist for it in Ubuntu Software Centre? Thanks in advance!
