Hi all, it is not clear to me what is the difference between “dnf upgrade” and “dnf distro-sync”

Very helpful but reinstall for a group not included. I am using MATE but it suddenly produced errors, e.g. “man package” leaves off first characters in the lines. Assume this is not a bug so am trying to reinstall “MATE Desktop” Other Desktops do not reproduce this error. Suggestions? Using Fedora 30 – up-to-date.

In reply to Jehosha.

Check whether your network connection is functioning properly.
If so, run ,
dnf clean all

then run dnf update

Hello Pradeep Kumar.

If only I had access to your knowledge, what a joy my Fedora 30 installation would have been. I am relatively new to the intricacies to Linux. I came to Fedora 30 from Ubuntu, most recently 19.04. Both distros have much to offer.

I do not know why, but Fedora seems more difficult to me. Perhaps it’s just getting the hang of its nuances.

I seek your counsel on one niggly problem I am currently having: trying to get Synaptic Package Manager to run on Fedora 30. From the Terminal, I enter sudo -s and provide the password when prompted. This is a carryover from Ubuntu.

Next, dnf install synaptic runs perfectly well and is available in the applications after installation is complete.

Now the problem: Synaptic starts just fine. But then, it prompts for ROOT’s password?!?!

I’ve tried with my sudo -s password. No joy.

Please, could you provide some guidance to help me overcome this problem? I should be most grateful.

Thank you very much for your consideration.

Rick

Every parameter I run with dnf command gives me the following error message:
Error: Failed to synchronize cache for repo ‘updates’

I have a brand new Fedora 27 installed, but cannot move on for this error.
