I installed Qt, again, on new installation of Ubuntu. It asked me for sudo password, which is not strange since it wants to write it's data in kind of restricted environment. But what if some cracker, has embedded a virus and went of distributing working software from trustworthy company, but when you start it, it also starts sequence of things that you don't want on your computer?

On Windows there was a verification, that whenever program asks you for administrator permission, you could kind of see that the installation file is trustworthy because not a single byte has been changed, the "Author: Google Inc." and block is colored blue, not yellow. Is there a way to have same in Linux? I don't need boxes and button pressing, but is there a way to verify "is current running process that of which name I know, unchanged official redistributed installation file?".

I know I could check checksums, but, not every software developer is giving you official checksums and it also kind of takes time. Is there a way to verify running application that asks me for sudo password?

So, use sudo to change to root: sudo su -
Then, install the package. No passwords will be sent to any malware as a result. Checksums are good, and I think that Qt will provide those if you need.

?, it requested plain password, program gave me pop-up and asked me for sudo password.

And in case I would need to download software from verified app developer, but doesn't provide checksums? Is there way to verify it?

I would doubt it if they don't provide at least md5 checksums

or do you mean how to find the checksum of the downloaded file? In this case md5sum is a command line utility to do that, should be inbuilt in ubuntu

Okay, off with MD5 checksums, we're off to a wrong direction. The original question is:

"How to verify a package that requests sudo password?"

Forget everything I said about checksums.
