Parece que aptitude unmarkauto realmente não remove o sinalizador "pendente para exclusão". Em vez disso, eu uso aptitude install <pkg> para marcá-lo como instalado manualmente e removê-lo da lista de pacotes a serem excluídos.
aptitude unmarkauto parece ter se comportado estranhamente para mim. Eu tinha inúmeros pacotes que apt-get autoremove queria remover:
# apt-get autoremove

Em seguida, executei aptitude unmarkauto em um subconjunto deles que queria manter. Isso causou duas coisas: primeiro, o comando aptitude queria remover os pacotes listados acima:

Em segundo lugar, todos esses pacotes também estão marcados como sendo instalados manualmente (em vez de apenas o subconjunto que eu solicitei):
# aptitude show <all-pkgs-originally-listed-by-aptget-autoremove> | grep ^Automatically | uniq
Automatically installed: no
#
O que está acontecendo aqui? O que aptitude unmarkauto fez? Obrigado pela sua ajuda.
Parece que aptitude unmarkauto realmente não remove o sinalizador "pendente para exclusão". Em vez disso, eu uso aptitude install <pkg> para marcá-lo como instalado manualmente e removê-lo da lista de pacotes a serem excluídos.
