O Arch Linux e a autenticação de pacotes



Veremos agora como efetuar a transição do antigo sistema utilizado pelo pacman para o novo sistema de pacotes autenticados.

Mais simples impossível (bem... eu acho):

# pacman -Syy
# pacman -S pacman
# pacman-key --init; pacman-key --populate archlinux


Para o caso daqueles que não utilizam nenhum repositório externo, ou opções extras no arquivo /etc/pacman.conf e seu arquivo /etc/makepkg.conf também esteja sem nenhuma modificação, basta os passos a seguir para por ordem na casa:

# mv /etc/pacman.conf /etc/pacman.conf-OLD
# mv /etc/pacman.conf.new /etc/pacman.conf
# mv /etc/makepkg.conf /etc/makepkg.conf-OLD
# mv /etc/makepkg.conf.new /etc/makepkg.conf


No meu caso, precisei copiar não só os repositórios externos, como opções e comentários de meu conf, ao final da mesclagem dos arquivos /etc/pacman.conf e /etc/pacman.conf.new, o resultado foi esse:

#
#  /etc/pacman.conf
#
#  See the pacman.conf(5) manpage for option and repository directives

#
#  GENERAL  OPTIONS
#
[options]
#  The following paths are commented out with their default values listed.
#  If you wish to use different paths, uncomment and update the paths.
#  RootDir     =  /
#  DBPath     =  /var/lib/pacman/
#  CacheDir     =  /var/cache/pacman/pkg/
#  LogFile     =  /var/log/pacman.log
#  GPGDir     =  /etc/pacman.d/gnupg/
# Caso algum usuário desavisado tente remover os pacotes abaixo, o Pacman pedirá confirmação para a ação.
# Mensagem típica: " Pacotes HoldPkg foram encontrados na lista. Você deseja continuar? [s/N] "

HoldPkg    =  pacman glibc

#  Atualizar primeiro o Pacman.
SyncFirst    =  pacman

###  Definição do agente de download padrão.

#

#  wget.
#  XferCommand = /usr/bin/wget --passive-ftp -c -O %o %u
#  XferCommand = /usr/bin/wget --passive-ftp -c -v -O %o %u

#  curl.
#  XferCommand = /usr/bin/curl -C - -f %u > %o
#  XferCommand = /usr/bin/curl -C - %u > %o

#  axel.
#  XferCommand = /usr/bin/axel -S4 -v -a -o %o %u
#  XferCommand = /usr/bin/axel -S4 -n2 -v -a -o %o %u

#  aria2c.
#  XferCommand = /usr/bin/aria2c --allow-overwrite=true -c --file-allocation=falloc --log-level=error -m2 --max- connection-per-server=2 --max-file-not-found=5 --min-split-size=5M --no-conf --remote-time=true --summary-interval=0 -t5 -d / -o %o %u

#  Método de limpeza.

CleanMethod = KeepInstalled

#  Arquitetura (i686, x86_64 ou auto).
Architecture = auto

#  Pacotes que não serão atualizados.
#  IgnorePkg    =
#  IgnoreGroup  =

#  NoUpgrade    =
#  NoExtract    =

#  Log mais detalhado.
#  UseSyslog
#  UseDelta

TotalDownload
#  CheckSpace
#  VerbosePkgLists

#  By default, pacman accepts packages signed by keys that its local keyring
#  trusts (see pacman-key and its man page), as well as unsigned packages.
#  SigLevel = Optional TrustedOnly

# NOTE: You must run `pacman-key --init` before first using pacman; the local
#  keyring can then be populated with the keys of all official Arch Linux
#  packagers with `pacman-key --populate archlinux`.

#
#  REPOSITORIES
#    - can be defined here or included from another file
#    - pacman will search repositories in the order defined here
#    - local/custom mirrors can be added here or in separate files
#    - repositories listed first will take precedence when packages
#    - have identical names, regardless of version number
#    - URLs will have $repo replaced by the name of the current repo
#    - URLs will have $arch replaced by the name of the architecture
#
#  Repository entries are of the format:
#      [repo-name]
#      Server = ServerName
#      Include = IncludePath
#
#  The header [repo-name] is crucial - it must be present and
#  uncommented to enable the repo.
#

#  The testing repositories are disabled by default. To enable, uncomment the
#  repo name header and Include lines. You can add preferred servers immediately
#  after the header, and they will be used before the default mirrors.

Realizadas as alterações, prossigo com:

# pacman -Syy
# pacman -Su
Na imagem abaixo, vemos um erro referente a autenticação do repo-ck, os passos para corrigi-lo são esses:

# pacman-key -r 6176ED4B
# pacman-key --lsign-key 6176ED4B
# nano /etc/pacman.conf
Adicionar a linha:

SigLevel = Optional TrustedOnly

E repetir os passos:

# pacman -Syy
# pacman -Su
Vemos abaixo a atualização do kernel -ck:
E a conclusão do sys-upgrade:
Abaixo vemos a instalação individual de pacotes sem nenhum questionamento:
