I am completely new to RHEL based OSes. Trying to switch from GNOME to KDE.
Followed the instructions at this link
Got some errors except for step 1. Adding some screenshots for reference.
Also this problem is occuring after I installed a product called EDB. (https://www.enterprisedb.com/)

Using a virgin (but updated) version of Rocky Linux 8.5, I am trying to install VMware Workstation 16.2.1 (and others), but get compile errors during the first attempt to run, when vmmon and vmnet are being built.
All the proper, current headers from kernel-devel and kernel-headers are installed.
I tried upgrading to the 5.16.4 kernal at kernel.org, with all associated headers, and basically get the same errors.
"Unable to install all modules." i.e., vmmon and vmnet
Posts i have found with searching the net seem to indicate that there was a "back-port" of an upstream fix to Rocky that has affected the ability to build the loadable kernel modules necessary to run vmware - but i cannot confirm this is actually the problem that I am experiencing.
So i simply ask these questions: Can anyone (today) install VMware Workstation 16.2.1 (or any version), on a fresh install of Rocky Linux 8.5?
If so, would you please point me at your installation instructions, because I am unable to build "vmmon" and "vmnet" modules today (2022-01-04), that allow me to actually run virtual machines with vmware? (The kernel modules fail to compile and build.)
(and after 15 years of using stackoverflow i do not have the reputation to create a "rocky-linux" question tag...)
See https://unix.stackexchange.com/questions/689436/the-vmmon-and-vmnet-vmware-workstation-kernel-modules-fail-to-build-on-rocky-lin
mbubecek's instructions work for a variety of releases and should compile perfectly and run without issue, if you follow his instructions.
I have successfully used these methods at least a half dozen times with Rocky 8.5 and 8.6 with vmware workstation 16.1 up to version 16.2.1
NOTE: This error is NOT Rocky Linux specific. Also happens on some versions of RHEL 8 and CentOS 8.x I would also expect this "fix" to work on all of the other linux versions that are RHEL 8-derived.
I've been having difficulty with the same issue, and a colleague pointed me to check my kernel. This is our "official" resolution. See if the below works for you.
This is due to differences between the kernel and the source code for the VMWare modules, see here for more information. You can get the correct kernel modules, and build them by executing the following commands
wget https://github.com/mkubecek/vmware-host-modules/archive/workstation-16.1.0.tar.gz
tar -xf workstation-16.1.0.tar.gz
cd vmware-host-modules-workstation-16.1.0/
make
sudo make install
If you get the error,
crosspage.c:53:16: fatal error: linux/frame.h: No such file or directory
The error is described here. The solution is to remove (i.e. comment out) the offending include file in crosspage.c After doing the sudo make install, it is a very good idea to restart you host.
You may need to manually insert the modules into the kernel the first time after running make install'. The kernel modules (vmmon.ko and vmnet.ko) will be found at /lib/modules//misc. The following set of command will do this:
cd /lib/modules/$(uname -r)/misc
sudo insmod vmmon.ko
sudo insmod vmnet.ko
The modules should be load automatically after a restart/reboot.
If you update vmware to a different version (say 16.2.1) you may need to this again. Just change the versions in the above commands. If you hit the update button on the splash-screen and failed to notice the version you are updating to, you can run `vmware -v' at a command prompt to get the version you updated to.
I created a Linux application in Qt 5.15.2 and packaged it to AppImage with linuxdeployqt. I do this on Ubuntu 18.04 virtual machine. The created AppImage runs without any problem on any Linux distributions which I have tried so far. Except Fedora 34 and Ubuntu 21.10, both with Gnome 4. The problem is obviously connected with Gnome 4 and it will probably bother many developers as Gnome 4 will be becoming more prevalent in the near future. But I have not yet found any satisfactory solution...
When I try to run my app from terminal on any Gnome 4 based distro, it shows this error:
./MyApp.AppImage
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
(MyApp.AppImage:2747): GLib-GIO-ERROR **: 08:56:35.632: Settings schema 'org.gnome.settings-daemon.plugins.xsettings' does not contain a key named 'antialiasing'
By trial and error, I found that this happens only if I add plugin platformthemes/libqgtk3.so when deploying AppImage with linuxdeployqt. If I do not bundle this library, then the final AppImage runs well with Gnome 4. But on the other hand, without this GTK3 plugin the application does not look good (theme, colors, icons, etc.) on al Gnome 3 and 4 based distros.
I googled for the root cause and a possible solution to this error and the most informative thing I found was this: https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1922464
So it seems that there is some clash with old GTK version (older than 3.24.26) and new Gnome 4. So I assume the same problem will we with all Gnome 40 based distros. I build and deploy my app with linuxdeployqt on Ubuntu 18.04 (virtual) machine, which has GTK 3.22.30, which is too old. The solution probably would be do compile and deploy my app on a newer version of Ubuntu. But the problem is that linuxdeployqt does not allow deploying AppImages with newer version than the OLDEST supported LTS version of Ubuntu.
I am unfortunately not a Linux expert, I have been always developing for Windows and started working partly on Linux some two years ago. So I am not sure what my options are.
A) Is it possible to install somehow newer GTK version on Ubuntu 18.04?
B) Is it possible to force somehow linuxdeployqt to work on newer Ubuntu?
C) Should I give up and create two versions of AppImages, one with libqgtk3.so plugin present (which will work everywhere except Gnome40-based distros) and the other AppImage without this plugin, which will work on Gnome40-based distros?
D) Any other way?
Regarding A and B: I am not sure if it is possible, how to do it and I would be worried about backward compatibility when run on for example Ubuntu 18.04, i.e. the oldest LTE.
Regarding C: Seems viable but it breaks the magic of one universal AppImages which should work everywhere... And another problem is that for example on Ubuntu 21.10 the application looks ugly without this GTK3 plugin...
Regarding D: is there any D at all?
I am currently running emacs on Gentoo linux. My intention was to use all-the-icons ivy (I also downloaded all-the-icons-ivy). Unfortunately, all the icons come out confusing.
I have already run all-the-icons-install-fonts, per the wiki instructions. Does anyone know what is happening?
You may lack the fonts for all-the-icons.
The all-the-icons documentation recommends installing the fonts by running this command in Emacs:
M-x all-the-icons-install-fonts.
Alternatively, you can try installing the fonts using the package manager for your OS. For Gentoo, there's a package for all-the-icons here.
I ran into a similar issue on an Arch based distro, and was able to resolve it by installing all-the-iconts. For those using Arch based distros, the package can be found here.
I have been using Anaconda 3-5.0.1 with spyder3. Spyder has begun to fail.
I tried to remove and reinstall but reinstall fails. I removed hidden folder
anaconda3 to no avail. I now have no working spyder. I am installing 64-bit version in Windows 10. There are a variety of error messages including cant create menus. I have run this install many times prior to today (2/8/2018).
I assume continuum changed something.
I would greatly appreciate guidance.
For those of you who still have the same issue, try to follow the link below.

You may need to have a google translate as it's a Japanese blog.
I deleted JDK, JRE and all java related paths in the environment setting as suggested in the blog. Then I could successfully install anaconda3.5.1.0_64bit with no error.
Introduction
I've just installed a networking simulator Called Netkit. On Debian stretch stable. Using the official installation guide here.
Installation
After setting the correct paths and installing. I then run the check_configuration.sh script.
Everything is checked OK, and it has found the terminal emulator xterm which is needed for netkit. And recieve the complete message.
[ READY ] Congratulations! Your Netkit setup is now complete!
Enjoy Netkit!
The Problem
Running netkit using the command:
vstart pc1
The xterm netkit-kernel emulator starts running. However I'm getting an infinite loop of the same error message:
ubda: can't open "home/foo/netkit/pc1.disk" failed, errno= 13
So im guessing it's because the file is missing? if so how do i obtain it? and if not, what is causing this error. I've followed the install guide completely.
I'm assuming your system is not a 32bit system. Netkit is only supported on the 32-bit architecture(unless the compatibility libraries are installed). Hence I would suggest you download a 32-bit VM(instead of installing the libraries) and run Netkit on the same(worked fine for me).
Check position of your lab-folder..
