man pages blank in chroot

[Roosta21]

HiI was wondering if any can help, I just cant seem to get man commanf to work properly within a chroot (im using jailkit), the command works but it does not pull any information.. I tried debugging using strace and i get the following result from strace on the chrooted man command and normal enviroment

I believe all the libaries are installed as it is loading fine just not pulling the info through


Jailkit

Well thats since the man pages are in a Directory that you havnt Chrooted.
I am not known how it works with Jailkit. I use Chroot+mount-bind+ln but. then I can run man and have blank pages. Since I dont have the dir were the Pages are.
I dont know were they are. Since I just use the man page on the net then
Hope that helped.

Are the man pages ie for ls "ls.1.qz? in a directory /usr/share/man/man1/l

As i thought the same the man pages may not be there but i think they are.. as they are full of command files that are gzip.. i then did a strace and the chroot account.. and i noticed it returned a access("/usr/share/man/man/man1/ls.1.gz so i un zipped the file

and ran a strace again... and seem to indicate the file was found and opened but it still returned a blank page


access("/usr/share/man/man/man1/ls.1.gz", R_OK) = 0
access("/usr/share/man/man1/ls.1", R_OK) = 0
open("/usr/share/man/man1/ls.1", O_RDONLY) = 5
open("/usr/share/man/man1/ls.1", O_RDONLY) = 5

Any ideas?

I have exactly the same issue.
Did you find any answers?

Is there any specific permissions to give to the man page? or to man a+s for ex.

Hope to get a reply asap, coz it is quite blocking for me.

Thanks a lot.
Fred.
