In some moment my MySQL server stopped working(I have installed my home kubuntu 22.04 several months ago)

I check commands :

# mysql

I found line :

 master-at-home mysql-systemd-start[32412]: MySQL configuration not found at /etc/mysql/my.cnf. Please create one.

I have no /etc/mysql/ subdirectory at all. I do not know why so and how restore /etc/mysql/my.cnf in my OS ?

On kubuntu 22.04 I reinstalled ssh-keygen :

 sudo ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa
Your public key has been saved in /root/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:Q40/XXXXXXXXXXXXXXXXX/XXXXXXX root@master-at-home
The key's randomart image is:
+---[RSA 3072]----+
|... ..           |
|oo.+o..  o       |
|.+.o=o+ = .      |

|    .E.+  o      |

But files were generated under /root/.ssh/id_rsa.pub, but not under /home/master/.ssh, where master is current user.

Not sure if I can move the files manually or to change my command in the console ?

under kubuntu 22.04 I have a pdf file and I need to make a ms word doc 97 file to edit it under both Libre Office Writer and ms word doc 97. If I open this file from Libre Office Writer the file is opened in Libre Office Draw application, which has no option to save file as word doc 97 file. In which way can I transorm my file in ms word doc 97 format ?

PS. maybe not ms word doc 97, but how to convert to MODERN(no sure which format current now) ms word doc format?

PS2: I try command and got error :

pandoc source.pdf -f pdf -t docx -o Agreement.doc
Unknown input format pdf
Pandoc can convert to PDF, but not from PDF.

In help I see :

UPDATED: I tried to follow commands, but got warning:

libreoffice --infilter="source.pdf" --convert-to docx  Settle.doc
Warning: failed to launch javaldx - java may not function correctly
convert /mnt/_work_sdb8/NSN/Settlement/Settle.doc -> /mnt/_work_sdb8/NSN/Settlement/Settle.docx using filter : MS Word 2007 XML

and I got empty Settle.docx empty - 4.1 kb Not sure which options/missing packages in my os I have migconfigured :

When under ubuntu 22.04 console in php/laravel app I run command.

php artisan route:list >> route_list.txt

new file is generated, if such file does not exists.

But is there is such route_list.txt file with content, if therte is a way to rewrite all content of this file?

I need to replace login user for phpMyAdmin on remote Ubuntu 20.

I opened file /etc/phpmyadmin/config.inc.php and modified $dbuser parameter:

# $dbuser='phpmyadmin';

$dbuser='NewUser';

$dbpass='Newpassword';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='3306';
$dbtype='mysql';

I am able to login with NewUser and Newpassword, but I also can entered into the system with root and Newpassword. My prior login phpmyadmin - does not work(I commented it above).

I restarted Apache with command :

sudo service apache2 restart

How to disable root user for phpMyAdmin?

Actually my dev site was hacked and I lost all my data on MySQL. Not big deal as it was dev site only, but how to make my site safer ? I think changing login to phpMyAdmin is one step... Any other?

Description: Docker: the open-source application container engine
Docker is a product for you to build, ship and run any application as a
lightweight container
.
Docker containers are both hardware-agnostic and platform-agnostic. This means
they can run anywhere, from your laptop to the largest cloud compute instance and
everything in between - and they don't require you to use a particular
language, framework or packaging system. That makes them great building blocks
for deploying and scaling web apps, databases, and backend services without
depending on a particular stack or provider.

Which commands have I to run on my desktop computer to have the same versions of Chrome?

In my kubuntu 20 I have :

git version 2.25.1

From my team-maneger I got notice that I need to update my git to version 2.29 or upper How can I do it correctly ?

Thanks!

New kubuntu 20 seems has no functionality "Freeze Task manager". Just exclude acassional removing of menu items in Task manager. But prior kubuntu had such functionality.

Can I add such functionality in kubuntu 20 ?

Description: Standalone GNU Info documentation browser
 The Info file format is an easily-parsable representation for online
 documents. This program allows you to view Info documents, like the
 ones stored in /usr/share/info.
 .
 Much of the software in Debian comes with its online documentation in
 the form of Info files, so it is most likely you will want to install it.

N: Unable to locate package —

Last line looks like error and I can not build my docker app...

Modified BLOCK # 1: Searching in net I found hints that reason of this error can be that some apps are not in $PATH So I added line with build-essential path :

export PATH="/usr/share/build-essential:$PATH"

in file /home/master/.bashrc and run update command :

source ~/.bashrc

After that I check that all related apops in PATH :

master@master-laptop:ProjectName$ $PATH
bash: /usr/share/build-essential:/home/master/.composer/vendor/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin: No such file or directory
master@master-laptop:ProjectName$ whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/share/gcc /usr/share/man/man1/gcc.1.gz
master@master-laptop:ProjectName$ whereis cc
cc: /usr/bin/cc /usr/share/man/man1/cc.1.gz
master@master-laptop:ProjectName$ whereis build-essential
build-essential: /usr/share/build-essential

But anyway I got the same error :

...
make: /bin/sh: Operation not permitted
make: *** [Makefile:192: imagick_file.lo] Error 127

Thanks!
