hello, (I repeat this message in English, my apologies)
I come from Windows, I am new to Linux and Ubuntu. I just installed Ubuntu 24.04 for the first time.
I have Windows 10 on an SSD and I installed Ubuntu on a different SSD. They remain in dual mode.
When installing I chose to start without asking for a password.
(when everything was complete and working I planned to change to "ask for password at startup")
Ubuntu starts fine, the OS was updated correctly (it did not ask for a password)
Wanting to install Applications, it asks for the password, I write it, the installation does not start and the message appears:
PackageKit error: PackageKitError.notAuthorized
Failed to obtain authentication
The password is fine, written carefully, but there is no way
I don't understand,
can anybody help me?
thank you and greetings
