Clone logical volume using dd
by Sreyan Chakravarty
Hi,
I use LVM on top of LUKS.
My entire root file system is on a logical volume. I have no seperate home
or swap partitions.
I would like to know how can I clone this logical volume to my external
hard disk.
I have seen commands like :
dd if=/dev/vg/root_lv of=/mnt/exthdd bs=64k conv=noerror,sync
status=progress
I have a couple of questions about this:
1) Why use noerror and sync?
noerror might give me a corrupted image and sync is just going to increase
the size of my image with padding.
Why use them?
2) What is rationale behind block size?
Will using 4M block size instead of 64K give me a different image? I need
my image to be an EXACT COPY.
Need your help.
Thanks.

Why is the LibreOffice group blank ?
by Sreyan Chakravarty
Hi,
I wanted to remove all LibreOffice components so I tried the following
command:
sudo dnf remove -y @libreoffice
This resulted in:
No packages marked for removal.
Dependencies resolved.
============================================================================================================================================================================
Package Architecture
Version Repository
Size
============================================================================================================================================================================
Removing Groups:
LibreOffice
Transaction Summary
============================================================================================================================================================================
Complete!
This was strange since the group had no packages in it.
Why is that ?
Just to confirm I installed the LibreOffice group once again via:
sudo dnf install -y @libreoffice
And that resulted in:
Dependencies resolved.

Why is there a blank group of LibreOffice ?
Why aren't the required packages in it ?

lost the meta key in gnome-terminal after 32 -> 33 upgrade
by Denis Shaposhnikov
Hi!
After upgrade my Fedora from 32 to 33 I found Meta key in the
gnome-terminal works strange. Looks like now the gnome-terminal
recognizes Alt key as Meta key. Everywhere in the system Win key is
the Meta key and in the gnome-terminal only Alt key is the Meta key. I
see it because before Win+Backspace deleted the whole word, but now it
deletes just one symbol and Alt+Backspace deletes the whole word. Does
anybody know how to return it to previous behavior?

HTML/PDF -
by Bob Goodwin
What is the best way to convert an HTML file to PDF. I have a two page
report in HTML form that I want to change to PDF. I can scan a printed
copy but I would like to convert the HTML file I received to PDF.
LibreOffice reformat it into a four page document, I would prefer to
keep the original two page style.

'smbclient' Crashing on Fedora 33
by Tim Evans
Have been working this on the BackupPC users mailing list, but it's
looking more like a general problem in F33's Samba utility, 'smbclient.'
BackupPC is a backup server package that uses Samba, rsync, and other
protocols to backup clients, including Windows PC's. Basically, it runs
a command like this for a SMB backup of a PC:
/usr/bin/smbclient \\\\new-pelican\\C\$ -U backup -E -d 2 -c tarmode\
full -Tc -
Output is piped to BackupPC utilities that unpack and index the backup,
and do other housekeeping
My backups have consistently failed since my upgrade to F33 (were
working without problems for years before, and most recently on F32).
Looking closely, it appears 'smbclient' is crashing after passing
exactly 47 files. (BackupPC then quits after data stops coming in.)
I've run this command at the command-line; it runs for a few seconds
then reports a core dump. Gnome shell then prompted me to file a
bugzilla, which I have done.
https://bugzilla.redhat.com/show_bug.cgi?id=1900232 "[abrt]
samba-client: remove_do_list_queue_head(): smbclient killed by SIGSEGV")
Anybody have further suggestions, please?

is this alphabetical sorting or what?
Thanks!

by Jonathan Ryshpan
Th KDE System Monitor Widget does not display Network Speed. There is
a box on the panel where the network load would normally be shown.
Relevant Sensors are:
"Download Rate" and "Upload Rate".
System is
* Fedora-33 (as of this afternoon)
* System Monitor Sensor 1.0
* KDE Frameworks 5.75.0
* Qt 5.15.1 (built against 5.15.1)
* The xcb windowing system
CPU load appears to be working properly.

Post F32->F33 upgrade rsync w ssh fails
by Max Pyziur
Greetings,
Even though I had done the F33 upgrade sometime ago, I am only now seeing
that it appears to have affected my rsync backups. When my CentOS server
issues the rsync backup the following error appears:
no hostkey alg
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at io.c(600) [receiver=3.0.6]
Any suggestions on how to resolve this? I've done some Googling; it seems
that crypto policies have been upgraded; general suggestion is to
regenerate keys; but so far I'm having no success restoring the rsync
process.
Much thanks as always,
Max

No that's not what I meant by reading.
I meant before you actually write to a disc, you have to have the data from
your original disc somewhere right ?
What would you use to record that from the original disc ? That's what I
meant.
Sorry for the confusion.
