Quoting Lepaca Kliffoth <[email protected]>:
If I'm right and "-xvf" doesn't preserve permissions, you won't be able to
upgrade or reinstall anything at all. I'm not _absolutely_ _sure_ this is
the reason of the particular failure you're reporting, but I think you
should definitely try again after unpacking the tarball with "-xpvf"...
--preserve-permissions
--same-permissions
-p
When `tar' is extracting an archive, it normally subtracts the
users' umask from the permissions specified in the archive and
uses that number as the permissions to create the destination
file. Specifying this option instructs `tar' that it should use
the permissions directly from the archive. *Note Writing::.
Look at the manual:
http://www.gnu.org/software/tar/manual/html_section/Attributes.html
‘--same-owner’
Create extracted files with the same ownership they have in the archive.
This is the default behavior for the superuser, so this option is
meaningful only for non-root users, when tar is executed on those
systems able to give files away.[...]
‘--preserve-permissions’
Extract all protection information.
This option causes tar to set the modes (access permissions) of
extracted files exactly as recorded in the archive. If this option is
not used, the current umask setting limits the permissions on
extracted files. This option is by default enabled when tar is
executed by a superuser.[...]
So unless you extract the tarball as a normal user, it will preserve
the permissions.
