Thank you for your kind response. I'm suspicious about one thing: DNF by default remove unused dependencies when user use "sudo dnf remove {package}". And I set Yum-extender (DNF) to remove unused elements. So, removal any application whether by using DNF or package manager, will lead to erase unused dependencies, So how these "unused libraries" remain ?? Could system update process lead to unused packages without erasing them during update process ?? Also, I'm very affraid about "libselinux-python": isn't it essential for security ?

Hi. I read about upgrade to Fedora 26, & I got the following bug documented:

https://fedoraproject.org/wiki/Commo....inthe_past

it said:

There was an unfortunate situation in the past few Fedora releases where PackageKit and DNF didn't work well together. If you installed something via PackageKit (used by GNOME Software or KDE Apper), it didn't mark such packages as "user installed" in the DNF database (which is used to differentiate user-requested packages from other packages installed purely as a dependency, but not explicitly requested by the user). Similarly, if you updated your system using PackageKit (GNOME offline updates, Apper), it erased such "user installed" flags from all updated packages. DNF then tries to remove any unnecessary packages during its next transaction (or when specifically asked using sudo dnf autoremove). This might lead to removing core system packages because DNF no longer sees them as "user installed" and considers them a no-longer-needed dependency. It is also possible that this might happen to you when performing a system upgrade from Fedora 24 to Fedora 26.

Fedora 25 and 26 hasn't been affected by this bug at all, and it was fixed in Fedora 23 and 24 since libhif-0.2.2-3. Current use of PackageKit (GNOME Software, Apper) should be safe. However, if you have ever used these tools in the past (and didn't follow these instructions when upgrading to Fedora 25), you're strongly advised to fix your "user installed" database before you try to upgrade to Fedora 26

The case is that:

1) I'm on Fedora 24 X64 bit Cinnamon edition,

2) I never installed or used GNOME software center before this bug is OFFICIALLY closed for Fedora 24,

https://bugzilla.redhat.com/show_bug....

I was put my eyes on it carefully.

3) I wait for about 4 months AFTER official closure of this bug for Fedora 24, then installed GNOME software center & started to use it to installed games.

4) I was using Yum-extender (DNF) for packages installation (before I discovered that it is buggy by long time. I discovered that it is buggy too late.),

5) I was already activated "remove unused elements" in Yum-extender (DNF),

6) output of "sudo dnf autoremove" is:

2017-03-30 00:02:02 -0500 commented answer How to block GUI from sudo on rootless account ??

Thank you for your help ! But I'm beginner in Linux less than 1 year. Can you kindly explain to me what pkexec ? Is it a package ? Is there a risk or complication if I limit it's access to specific user ? How can I achieve this safely ?

Best.

2017-03-28 14:30:22 -0500 commented question How to block GUI from sudo on rootless account ??

What you mean ? I was very clear: - I'm unable to login as su in the new rootless account - I'm unable to login as sudo in the new rootless account Both are O.K & this is my target, BUT: - in rootless account still GUI utilities that need sudo, like Firewall, still can take sudo password of 1st owner account in-spite that it rejected by terminal of rootless account !!! This is the problem

2017-03-28 07:49:43 -0500 asked a question How to block GUI from sudo on rootless account ??

I created new user account. This, due to default configuration of Fedora has no access to sudo (not in wheel group by default). Then I perform the following (from within 1st owner account):

sudo vi /etc/pam.d/su then uncomment the following line:

auth required pamwheel.so useuid then save & exit

So, currently, if I login to the new (rootless account) & open terminal & try the following:

  • "sudo dnf upgrade" & can not excute it NEITHER BY 1st owner account password NOR by rootless account password. Both passwords do not work.

Trying to use:

su

I can not log in as root by my root passsword (password of su not password of sudo nor password of rootless account)

Till now every thing is O.K

But if I'm within (login) new rootless account, I still able to open package manager or Firewall GUI then change system by entering sudo password of 1st owner account ! How this ?! This password rejected by terminal of new rootless account, so how can I use it from GUI while I'm within this new rootless account ?!

Examples on these GUI:

  • Yum extender (DNF) which still can remove, upgrade, ..... packages by enter sudo password of 1st owner account while I'm within rootless account !! -Firewall
  • Users & group
  • change time

How can I disable this ??
