This is probably preaching to the choir, but why are Fedora / RHEL / AlmaLinux so broken?

I decided to try them out in VirtualBox after many years of not using them. Results so far:

Fedora 34, repeatedly crashes during the "welcome" screen. This is where Gnome 4 asks you to set up your user name and details. Maybe it's some kind of Wayland/Gnome4 incompatibility with VirtualBox?

For AlmaLinux (a CentOS replacement), based on RHEL 8: I can't even install Okular. I tried doing "yum update" and rebooting, but the results are the same.

Installing from the "software center" also gives an error, but doesn't tell you what it is (clicking on the message does nothing):

Not sure if this is RedHat's fault, or AlmaLinux's. AlmaLinux is supposed to be binary-compatible (or identical), like CentOS and Rocky Linux.

Also, "yum update" asks what sounds like unreasonable questions:

Is this OK? How am I supposed to know? Isn't the system keeping track of trusted certificates and all that jazz?

Was I just very unlucky? Using Fedora / RHEL / AlmaLinux incorrectly due to inexperience?

NoScript won't allow me to see the pictures on Imgur, and I don't want to switch it off, so answering blindly.

Okular is not provided by RHEL/CentOS/AlmaLinux. It's provided by EPEL which is a third party repository albeit a renown one. But RHEL/CentOS/AlmaLinux provide epel-release which you have to install first, in order to configure EPEL repository.

When running dnf upgrade for the first time after that, you'll be asked to confirm import of EPEL GPG key. See RPM and GPG: How to verify Linux packages before installing them.

I tried embedding the images by enclosing them in IMG tags, but they are still shown as links. Not sure if this is board policy or my ineptitude, but if any moderators could embed the images for me, I'd appreciate it.

I am also not going to view the pictures.

Using CentOS 7 as a host running VirtualBox 6.1.26 I successfully installed Fedora 34 without problems.
I also installed Rocky 8.4 back in July and it worked ok but deleted the VM. I have not tried almalinux yet.

Without knowing anything about your host nor how you are configuring your guests it is difficult to say why you are having such bad luck.

You should be able to attach a screenshot picture.

Click the go advanced button and select the paperclip.

max.b, have you checked the date on the virtual machine?

OP provided direct image links, you don't need js for that.

But I tend to agree; half of the screenshots are merely illustrative, the other half could either be typed out or attached.

When I click on them, I get redirected to the same URL without the .png part and all I can see is a black screen. When I just set imgur.com as Temp. Trusted in NoScript, it will list blocked scripts from five additional sources, and the screen remains black.

Ok. I allowed scripts from media-lab.ai as well. Now I can see the screenshots.

Update. This is interesting. I disabled scripts from imgur.com and media-lab.ai again, but clicking on the links now brings images. Even after clearing cookies from imgur.com.

@OP. Okular requires poppler-qt5. poppler-qt5 is provided by repository powertools. Repository powertools is disabled by default on RHEL clones because it's an equivalent of CodeReady Linux Bulder repository in RHEL 8 which is disabled there by default as well (a stupid decision by Red Hat release managers, IMO). Run
and try installing Okular again.

shruggy, imgur direct image links (those that start https://i.imgur...) can be fed to e.g. feh directly, e.g.:
Sorry for the partial derailement to OP.

I attached the screenshots, in case people feel more comfortable with that. It's too bad they can't be embedded in the text.
