Problemas com permissão de acionadores

Question

Eu estava formatando as partições /var e /home para remover a criptografia, mas para isso fiz um backup de todo o seu conteúdo para restaurar mais tarde. Mas quando iniciei o sistema após o processo, percebi que o diretório /var tinha problemas de permissão. Ao instalar programas via apt-get , recebo o seguinte erro:

Processing 'triggers' for man-db (2.7.0.2-5) ...
Fopen: Permission denied

Minha estrutura /var

Root @ lDebian13: / var # ls -all

Como posso resolver este problema? Não sei o que fazer.

Talvez este tenha uma solução.

I have made progress figuring out the root cause (literally).

/var/cache/man needs to be recursively owned by user "man". Many of the locale subdirs were owned by user "root". If you down a "chown -R man /var/cache/man" this problem goes away.

Each of the successive fopen errors seems to be related to updating manpages for each of the locales (thanks to mib_chrol in ##nexenta for finding the open64 call that triggers this)

This is why running /usr/bin/mandb as root does not trigger errors, but dpkg related tools will (as these seem to update /var/cache/man in the context of the "man" user).

I just ran into this bug too, and there's not only /var/cache/man, but also /var and /var/cache need to be chmod'ed to 755
