If you mean during the installation of Fedora Core
itself, then I don't think Tomcat is provided with
Fedora Core (please feel free to correct me if I'm
wrong).
This means you will probably need to download Apache
Jakarta Tomcat (either binaries, or the source which
you'll need to build) and install it.
Hope this helps.
All the best,
Rahul

Virtualbox vs VMware for Fedora?
by Sbob
All;
I am running Fedora39, I have run VMware workstation for years, and I
have on and off had issues since VMware does not officially support
Fedora, normally I run a patch after each kernel update and it mostly
just works.
I am also running the osx unlocker so I can run mac VM's
I recently tried virtualbox on a spare laptop, havent looked at
virtualbox in years, and I was impressed, a few questions for the community:
- can I run the osx unlocker with virtualbox?
- does virtualbox have the same issues where it needs a patch after
each kernel and sometimes
just breaks with a new kernel , even with the patch?
Thanks in advance

firefox keeps freezing on me
by Michael Hennebry
My firefox on F38 freezes a lot.
I get "Firefox" is not responding a lot.
At one time, I thought it was because of too many windows and tabs open.
I closed several windows.
Shutting it down and bringing it back up often helped,
but not necessarily for very long.
According to top, firefox freezes even when the load
average is less than two, most of swap is free
and neither firefox nor its minions are near the top of top.
My new suspicion is that it waits for something
that does not happen often enough.
How do I diagnose this?

Upgrade KDE Wayland Spin 38->39 KDE Background Screen Issue
by richard emberson
Upgrade KDE Wayland Spin 38->39 KDE Background Screen Issue
KDE Screen Issue (or Plasma issue, or...)
1) Login screen comes up and can login.
2) KDE screen mix of colors and black... moving mouse and screen continues
to redraw random colors (but, mostly black).
3) Bottom panel (in hide mode) comes up and looks normal. Top ToolBar
is drawing like the screen (not normal) but I can tell its being drawn
ontop of the screen background (different colors/black).
5) Firefox comes up rendering like normal.
6) Thunderbird asks for password and it comes up drawing like normal.
7) Using Mouse Right Button, menu come up (look normal) and can
8 "Open Terminal". Kconsole comes up like normal.
9) From Kconsole can launch alacritty multiple times all normal.
10) Background and ToolBar still not rendering correctly.
11) Can move mouse over ToolBar and popups appear. Can also click and
launch/hide terminals, firefox, thunderbird when mouse if over their
position in ToolBar.
12) I can render a jpeg photo in eog and it comes up just fine.
With Fedora 38 KDE Spin I did not have this issue with the background
or ToolBar.
So, has anyone seen this behavior?
Where do I start?
Thanks.
Richard

Python code error in F39, but not in F38
by Ranjan Maitra
Hi,
I was running the code here: https://github.com/maitra/Visual-Information-Fidelity---Python3
However, the code runs in F38 (python 3.11) without error, but not in F39 (python 3.12) where it
ends with a segmentation fault (after doing the calculations).
Both, however, give an answer that are not the same after the 14th
decimal place. Not sure if I should be bothered about that.
Looking at valgrind, I can not tell if there is an error in the python call itself. Here is what I get (note that the code calls shared objects created by the gcc compiler).

Black screen after login to F39
by Michael Eager
I upgraded from Fedora 38 to Fedora 39 on an AMD Ryzen 5 5600
with Nvidia Geforce RTX 3050 graphics card. I'm running KDE
Plasma-X11, not Wayland.
I tried to install the GPU drivers several ways using repos/RPMs,
but was not successful. I am using the Nvidia proprietary
drivers. They support dual monitors with no problems; I've had
problems with the nouveau driver and dual monitors in the past.
I start the system in multi-user (CLI) mode and then run "startx"
to start X11 and Plasma. (I started doing this in F38 because of
sddm hanging, which I was not able to resolve.)
When I log in with my user account and run startx, I get a black
screen (extending across both monitors) with an X cursor. The
cursor moves in response to the mouse, but neither left or right
mouse button do anything. I can get to an alternate console
using alt-F3 and kill the login.
I have discovered a bit of a rain dance to get a working system. I
can log in as root, run startx, and get a working KDE Plasma-X11
screen. Then I log out to the sddm screen and log in again with
my user account. After this, everything (or almost everything)
works correctly.
I've checked the system logs and the Xorg log for any error
or warning messages, but nothing looks incorrect or at all
informative.
Does anyone have any suggestions or insights into this problem?

'--skip-broken' to skip uninstallable packages)
[hennebry@fedora ~]$
--allowerasing would seem to be the only suggestion likely to result in a
functional ffmpeg,
but I do not kow what damage that would cause.
Suggestions?
I was hoping for a --dry-run or some such option,
but no such luck.

NFS Mount Point Write Failure
by Stephen Morris
I have a network drive being mounted from the following entry in /etc/fstab:
192.168.1.12:/mnt/HD/HD_a2 /mnt/nfs nfs
users,nconnect=2,owner,rw,_netdev 0 0
This results in the following definition in /etc/mtab:
192.168.1.12:/mnt/HD/HD_a2 /mnt/nfs nfs
rw,nosuid,nodev,noexec,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,proto=tcp,nconnect=2,timeo=600,retran
s=2,sec=sys,mountaddr=192.168.1.12,mountvers=3,mountport=57759,mountproto=udp,local_lock=none,addr=192.168.1.12
0 0
I can read from the mount point but I can't write to it.
A touch /mnt/nfs/filetest.txt fails with a read only volume error:
touch: cannot touch '/mnt/nfs/filetest.txt': Read-only file system
Can anyone guide me on what I am doing wrong, I am using F39, and I
believe the fstab specification worked fine in F38 before I upgraded to F39.
regards,
Steve
