Em algum momento meu servidor MySQL parou de funcionar (eu instalei meu Kubuntu 22.04 doméstico há vários meses)

Eu verifico os comandos:

# mysql

Eu encontrei a linha:

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

Não tenho nenhum subdiretório /etc/mysql/. Não sei por que e como restaurar /etc/mysql/my.cnf no meu SO?

No kubuntu 22.04 reinstalei o ssh-keygen:

Mas os arquivos foram gerados em /root/.ssh/id_rsa.pub, mas não em /home/master/.ssh, onde masterestá o usuário atual.

Não tenho certeza se posso mover os arquivos manualmente ou alterar meu comando no console?

no kubuntu 22.04 eu tenho um arquivo pdf e preciso criar um arquivo ms word doc 97 para editá-lo no Libre Office Writer e no ms word doc 97. Se eu abrir este arquivo no Libre Office Writer, o arquivo será aberto no Libre Office Draw aplicativo, que não tem opção de salvar o arquivo como arquivo word doc 97. De que forma posso transformar meu arquivo no formato ms word doc 97?

PS. talvez não ms word doc 97, mas como converter para MODERN (não tenho certeza de qual formato atual agora) formato ms word doc?

PS2: tentei o comando e obtive erro:

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

Na ajuda eu vejo:

ATUALIZADO: Tentei seguir os comandos, mas recebi um aviso:

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

e fiquei vazio Settle.docx vazio - 4,1 kb Não tenho certeza de quais opções/pacotes ausentes em meu sistema operacional eu configurei mig:

lsb_release -d; uname -r; uname -i
Description:    Ubuntu 22.04.3 LTS

x86_64

Quando estou no console do Ubuntu 22.04 no aplicativo php/laravel eu executo o comando.

php artisan route:list >> route_list.txt

novo arquivo é gerado, se tal arquivo não existir.

Mas existe tal arquivo route_list.txt com conteúdo, se houver uma maneira de reescrever todo o conteúdo deste arquivo?

Preciso substituir o usuário de login do phpMyAdmin no Ubuntu 20 remoto.

Abri o arquivo /etc/phpmyadmin/config.inc.phpe modifiquei $dbusero parâmetro:

# $dbuser='phpmyadmin';

$dbuser='NewUser';

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

Consigo fazer login com NewUsere Newpassword, mas também posso entrar no sistema com roote Newpassword. Meu login anterior phpmyadmin- não funciona (comentei acima).

Eu reiniciei o Apache com o comando:

sudo service apache2 restart

Como desabilitar rootusuário para phpMyAdmin?

Na verdade, meu site de desenvolvimento foi hackeado e perdi todos os meus dados no MySQL. Não é grande coisa, pois era apenas um site de desenvolvimento, mas como tornar meu site mais seguro? Acho que mudar o login para phpMyAdmin é um passo... Qualquer outro?

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.

Tendo 2 layouts de teclado no meu kubuntu 20.04

Eu configurei as teclas de atalho Alt direita nos Shorts principais: https://prnt.sc/6BELdro2eHZc Abrindo a guia Avançado Vejo o bloco “Mudando para outro layout” com a opção “Alt direita” definida: https://prnt.sc/o8uRyOHM7-VE Mas se no layout padrão em inglês eu pressionar a tecla “Alt direita”, tenho o idioma ucraniano definido como atual. Mas pressionando a tecla “Alt direita” mais uma vez, meu layout não mudou para o inglês como eu esperava. Perdi algumas opções nas minhas opções de layouts?

Quais comandos devo executar em meu computador desktop para ter as mesmas versões do Chrome?

No meu kubuntu 20 eu tenho:

git version 2.25.1

Do meu gerente de equipe, recebi um aviso de que preciso atualizar meu git para a versão 2.29 ou superior. Como posso fazer isso corretamente?

Obrigado!
