Question on difference between dnf upgrade versus clean install?
by Michael D. Setzer II
I've got 5 Fedora machines at my house. Recently
upgraded a couple since FC30 was becoming EOL.
Some I did a clean install. New Hard disk, and install
from iso. Usually, that takes about 1/2 hour for whole
process. Including install of OS, and then install of a
number of other packages I use that are not installed by
default.
Did update on my notebook machine as well using dnf
system update. This system has some more packages
installed. Showed 5070 versus about 2000+ for the
clean install. Download process took about 30 minutes,
but then the reboot and upgrade process took just over
14 hours. Total was 14 hours 50 minutes.
Not clear why it would take 15 times as long? Checked
while running, and dnf was running at 100%, but just
using 1 cpu. Notebook has dual cpus. Don't know if
others just run it, and check when done, but seems to
be a bigger difference in time than it should be.
Thanks and be Safe..

Workspaces lost -
by Bob Goodwin
I removed a mysterious blank area on the panel and all my workspaces
went with it. I have not been able to restore them with the Panel
Preferences GUI. Changes there are ignored.
Apparently it needs the workspaces restored first and I have no idea how
to do that.
This updated Fedora 32 using xfce, any siggestions welcome, Bob

Fedora 32: Anyone have success building akmod-xtables-addons ?
by Bill Shirley
For years I've installed akmod-xtables-addons with no problems. Not so with Fedora 32.
It has a build error (excerpt):

USB rtl8192eu not connecting.
by Michael D. Setzer II
I've tried two usb rtl8192eu devices I've used in the
past, but now I can not get either to connect with
Fedora 30 or Fedora 31?
The devices load, and will even see the wifi, but the
connection fails.

[107116.406750] wlp0s20u2: authentication with

Have tried with a notebook with built-in wifi, and it can
connect to either wifi no problem. So, know password
and all are correct. Tried on desktop system without
built-in wifi, and it get the same error.
Is there something that might cause the failure, or is
there a way to see more detail on the error. Just says
connection failed.
Thanks.

Raid array empty after restart
by Patrick O'Callaghan
Still getting the hang of md. I had it working for several days (2
disks in RAID1 config) but after a system update and reboot, it
suddenly shows no data:

How is this possible? The only thing that touches the array is a borg
backup run from crontab, which I have verified is working correctly,
including just before the update and reboot this morning. It looks as
if the mount is mounting the wrong thing.
Or am I missing something very obvious?

Any thoughts on where I can get a driver for it to print large photos?
Or even the driver for it's predecessor the P800?
Thanks

troubles starting virt-manager as a user
by ToddAndMargo
Hi All,
Normally when I start virt-mamager, I get a root password
prompt from xfce-polkit. I accidentally pressed
"Deny". Now it won't start from a user anymore
But I can start it from a shell as user root.
But I can not use "su" or "beesu" to start it
from a user's account:
$ su root -c virt-manager
Password:

wayland or not with nvidia
by hw
Hi,
what is the current status of wayland with nvidia drivers in Fedora 32?
Some search results seem to indicate that it's supposed to work by default.
Others indicate that it still doesn't work. The actual result is that it
does not work unless I use the nouveau driver instead. Unfortunately, the
lack of performance with nouveau still requires nvidia drivers.
If it's supposed to work, how do I get it to work?

bash/awk equivalent code to gnu datamash
by olivares33561＠protonmail.com
Dear fellow fedora users,
If I have a data file called 15.dat with the following content:
$ cat 15.dat
1
3
1
0
2
And I want to find min, quartile 1, median, quartile 3 and maximum (Five number summary)
We can use datamash like
$ cat 15.dat | datamash min 1 q1 1 median 1 q3 1 max 1 0 1 1.5 2.75 6
Q3 is reported as 2.75 but if we split the data file in half the number is 3.
$ sort 15.dat
0
1
1
2
3
6
$ cat GF19.dat
14
0
4
0
0
1
1
7
1
0
3
1
2
0
$
$ sort GF19.dat
0
0
0
0
0
1
1
1
1
14
2
3
4
7
$
Is incorrect, the 14 is biggest or max
We use -n for numeric
$ sort GF19.dat -n
0
0
0
0
0
1
1
1
1
2
3
4
7
14
It works but q3 is also 2.75 but by hand is 3
$ cat GF19.dat | datamash min 1 q1 1 median 1 q3 1 max 1
0 0 1 2.75 14
$
If we apply a code using sort and awk
From
https://unix.stackexchange.com/questions/13731/is-there-a-way-to-get-the-...
we can get min, max, median and average
sort -n | awk '{a[i++]=$0;s+=$0}END{print a[0],a[i-1],(a[int(i/2)]+a[int((i-1)/2)])/2,s/i}'
How can we find q1 and q3 to generate five number summary? And does it give 3 for q3 for both files. I want to use datamash, but question why it outputs 2.75 and not 3?
7
14
$ cat 15.dat | sort -n | awk '{a[i++]=$0;s+=$0}END{print a[0],a[i-1],(a[int(i/2)]+a[int((i-1)/2)])/2,s/i}'
0 6 1.5 2.16667
$
It outputs min, max, median and average. Average is optional. Only min, q1, median, q3 and max is needed.
Thank you in advance,
Antonio
