Tenho usado vinho, mas não deu certo, então parei de usá-lo.

depois que o 7-zip para vinho ainda estava presente no gnome-menus(Menu de aplicativos) Como posso consertar isso

Eu removi wineo instalado do mainrepositório. Eu removi winehq-stabledo winehqmeu próprio repositório

se eu digitar sudo apt-get remove --purge wine winehq-stable diz:

Building dependency tree... Done
Reading state information... Done
Package 'wine' is not installed, so not removed
Package 'winehq-stable' is not installed, so not removed

Como posso consertar isso?

Eu já instalei gallery-dldo apt, que é 1.26. Eu quero uma versão mais nova, então eu instalo do snap. O Snap me informa que eu instalei a versão 1.28.

No entanto, quando naveguei para /snap/gallery-dl/current/bine executei ./gallery-dl --version, ele ainda relata 1.26 - a mesma versão exata que obtive com o apt. E quando naveguei para /snap/bin, executei com o binário naquela pasta, obtive o 1.28 correto.

Então qual é o caminho correto para o snap binary? /snap/binou /snap/PACKAGE_NAME/current/bin?

Pelo que sei, devo conseguir instalar o atcomando da seguinte maneira:

sudo apt update
sudo apt install at

No entanto, estou recebendo o seguinte:

Reading package lists... Done

Reading state information... Done
Package at is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Estou no Ubuntu 24.04 LTS.

Estou ciente das implicações de segurança e entendo por que o uso de apt-key foi descontinuado . Para meu caso de uso, não me importo.

Eu quero correr:

$ apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382

sem ver nenhum aviso. No entanto, vejo:

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
Executing: /tmp/apt-key-gpghome.KVaQ390iTM/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 /dev/null
gpg: "/dev/null" not a key ID: skipping

gpg: Total number processed: 1
gpg:              unchanged: 1

Como forçar nenhuma saída para stdout e avisos? Eu só quero ver a saída de um erro real acontecendo. (Estou ciente de que o script está sendo executado em um sistema que já conhece a chave, pois eu já o executei antes.)

Tentei:

  • apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 > /dev/null
  • apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys CC116F55AA7F2382 2>&1 > /dev/null

Ao inicializar um computador com Ubuntu 24.04.1 LTS, recebi esta mensagem hoje:

Oh no! Something has gone wrong.

Quero obter os nomes bem localizados dos pacotes APT, como "LibreOffice Writer" (e não libreoffice-writer). Estou escrevendo um script que precisa dessas informações.

Posso obter a descrição localizada de um pacote usando um comando como apt show libreoffice-writer. No entanto, ele não mostra o título localizado do pacote. Só consigo encontrar libreoffice-writercomo um nome, não consigo encontrar LibreOffice Writerem nenhum dos campos que apt showimprime.

Eu sei que esse nome localizado está armazenado em algum lugar. O Update Manager do Ubuntu está recuperando esse nome de algum lugar, como você pode ver nesta captura de tela:

Tentei instalar libmagick++-dev(pergunta relacionada: Como instalar libmagick++-dev no Ubuntu 20.04? ). Mas é preciso fazer downgrade de vários pacotes. Reverti vários deles. Mas, como se viu, o restante do downgrade requer a remoção de muitos dos pacotes instalados. Decidi não fazer isso. Agora, gostaria de restaurar as versões anteriores dos pacotes instalados. Como posso fazer isso?

Há um problema com dependências.

Tentei recomendações da pergunta semelhante: Problemas de dependência ao instalar libmagick++-dev no Ubuntu 18.04

Eles não ajudaram.

Este pacote deve ser possível de instalar com downgrade proposto de outros pacotes. Mas esse downgrade requer a remoção de muitos programas instalados. Existe uma maneira de mantê-los e instalá-los libmagick++-dev?

Se não for possível, como reverter pacotes rebaixados? Tentei reinstalar versões instaladas anteriormente (atuais), mas aptpor algum motivo parei de vê-las após o downgrade. Criei uma pergunta separada sobre isso: Como reverter pacotes rebaixados?
