[Solved] dCore-buster64rc and man-db

(1/1)

volkerp:
I didn't have problems viewing manual pages in  dCore-stretch. In dCore-buster64 I ran into a problem I'm unable to solve:


--- Code: ---tc@box:~$ man man
man: nroff: Bad system call
man: command exited with status 159: (cd /usr/share/man && /usr/lib/man-db/zsoelim) | (cd /usr/share/man && /usr/lib/man-db/manconv -f UTF-8:ISO-8859-1 -t UTF-8//IGNORE) | (cd /usr/share/man && preconv -e UTF-8) | (cd /usr/share/man && tbl) | (cd /usr/share/man && nroff -mandoc -Tutf8)
tc@box:~$

--- End code ---

Any advice appreciated. Thanks in advance!

Hi volkerp
A couple of ideas. Does it still crash if you start it like this:

--- Code: ---MAN_DISABLE_SECCOMP=1 man man
--- End code ---

Try downgrading  man-db  back to the one supplied by  dCore-stretch.

You're very welcome.

Just to add some context to that solution, a  sandboxing  issue was mentioned as the cause of the problem and this
creates a security exception for the man program.

You can probably get this to work automatically by adding this to the  export  section of your  .profile  file:

--- Code: ---export MAN_DISABLE_SECCOMP=1
--- End code ---
Then logout and login.
