Atualmente, sudo
será solicitada uma senha, mas absolutamente nada acontece depois disso. Sem erros de qualquer tipo.
Eu verifiquei o arquivo sudoers, ele passou na verificação de sintaxe visudo, eis a configuração:
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults env_reset
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
# Host alias specification
# User alias specification
# Cmnd alias specification
# User privilege specification
root ALL=(ALL:ALL) ALL
# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL
# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL
# See sudoers(5) for more information on "#include" directives:
#includedir /etc/sudoers.d
O arquivo tem 0440 como permissão. Eu me adicionei ao grupo sudo
e admin
.
Aqui está o que parece quando tento usar o Sudo:
kml@rhythmsdev:/etc$ sudo apt-get update
kml@rhythmsdev:/etc$
Como você pode ver, nenhum erro. Ele simplesmente retorna ao prompt.
Aqui estão as permissões de arquivo
-r--r----- 1 root root 723 Feb 1 10:10 sudoers
sudoers.d
drwxr-xr-x 2 root root 4096 Feb 4 16:46 .
Aqui está a saída de id
um dos usuários em que estou tentando fazer o Sudo trabalhar:
uid=1010(kml) gid=102(develop) groups=102(develop),4(adm),27(sudo),106(admin),110(ftp)
Como eu realizei a atualização.
Realizei a atualização usando do-release-upgrade -d
SSH, mas com acesso físico possível através de uma viagem pelo corredor.
Aqui está o conteúdo do /etc/sources.list

success
Os nomes foram alterados para proteger os inocentes. Eu apareço duas vezes, por algum motivo. Mas nenhum dos outros colegas de trabalho também pode usar o Sudo (aqueles que poderiam ser pré-atualizados de qualquer maneira).
Aqui está a saída de mais alguns comandos.
visudo o arquivo sudoers e adicionado
kml ALL=(ALL:ALL) ALL
sob a linha raiz
sudo -i echo success
retornou o mesmo de antes, nada.
echo foo | sudo tee foo.txt; ls -l foo.txt
produziu:
ls: cannot access foo.txt: No such file or directory
Como eu reinstalei o Sudo.
Eu consegui isso duas vezes.
A primeira vez que corri
apt-get install --reinstall sudo
--De raiz
Isso fez pouco, então eu desinstalei primeiro via:
apt-get uninstall sudo
seguido por
apt-get install sudo
Editar mais informações, redigitadas
sudo
retorna silencioso após a autenticação da senha e não pergunta novamente.
sudo -k
e sudo -K
também falha silenciosamente. Eu estava logado como root. Ele solicita uma senha em uma conta normal.
Mais informações 2
Eu corri tail -f /var/log/auth.log
Aqui está o resultado da minha sudo ls
conta kml
Feb 6 16:33:27 rhythmsdev sudo: pam_unix(sudo:session): session opened for user root by kml(uid=1010)
Feb 6 16:33:27 rhythmsdev sudo: pam_unix(sudo:session): session closed for user root
A tentativa de uma senha incorreta solicita uma nova senha e registra isso

Isso parece interessante, é diferente de um servidor com sudo funcionando

Obrigado,
Estou sem ideias no momento.
sudo -u kml echo success
de um usuário não root, nada acontece. Se eu sudo -k echo success
for solicitado, digite uma senha e nada acontecerá.
