Recentemente vimos aqui como instalar a nova versão do navegador Opera, o Opera Developer no Debian e no Ubuntu, agora veremos como instalá-lo no Slackware. O empacotamento e instalação se dará por meio de um script que encontrei, script esse criado por Ruari Odegaard, desenvolvedor da Opera Software.

Abaixo veremos o conteúdo do script que aqui salvei em minha pasta $HOME/bin, salve-o onde desejar e com o nome que achar melhor, aqui usei o mesmo nome da dica a ser referenciada, ou seja, "latest-opera.sh", segue o script:

#!/bin/bash
# latest-opera Version 2.0RC3

# This script will find the latest Opera Developer binary package,
# download it and repackage it into Slackware format.

Fiz apenas algumas pequenas modificações no script (não removendo nada de seu conteúdo original), são elas:

1) TAG=${TAG:-_SBo}
2) PKGTYPE=${PKGTYPE:-txz}
3) find . -name 'opera_sandbox' -exec chmod 4711 {} \;
4) makepkg -l y -c n "$PACKAGE"

1) Altera a TAG padrão para o já tradicional _SBo (pode ser qualquer uma).
2) Modifica o formato de compressão para o .txz (economiza espaço em disco).
3) Previne erro no empacotamento ao executar o comando chmod.
4) Modifica o esquema de empacotamento do makepkg.

Após salvar e dar permissão de execução ao script, execute-o:

sudo latest-opera.sh
$ sudo installpkg /tmp/opera-*.txz

Blacklist

Caso você já tenha o velho navegador Opera 12.16 instalado, o Slackpkg acusará a existência de 2 pacotes com o mesmo nome (embora usem pastas diferentes), aí bastará adicioná-lo no arquivo /etc/slackpkg/blacklist:

sudo slackpkg upgrade-all

Checking local integrity... DONE
You have a broken /var/log/packages - with two versions of the same package.
The list of packages duplicated in your machine are shown below, but don't
worry about this list - when you select your action, slackpkg will show a
better list:

opera-12.16-i686-1_SBo
opera-30.0.1835.6-i686-1_SBo

You can (B)lacklist, (R)emove, or (I)gnore these packages.
Select your action (B/R/I): B

Vejam como ficou o arquivo:

cat /etc/slackpkg/blacklist


Eu realmente gosto do Opera 12.16 por causa do cliente de email e da rapidez (se comparado a qualquer outro), mas para aqueles que não curtem, melhor remover a velha versão e usar a mais recente bem mais compatível com qualquer site.

De ruim nessa estória de Opera novo, Vivaldi etc é que ambos precisam do pacote pepperflash-plugin do Chrome|Chromium, que no Slack vocês podem obter através do links abaixo:
