[GAP Forum] installation problems with 4.8.2

[Alexander Konovalov]

Dear Benjamin, dear GAP Forum,

Thank you for reporting this - we have heard this three times so far,
from users installing GAP as root outside their home directories (this
will not affect you if you install and run GAP as the same user).

What happened is that several packages were released with files not 
having appropriate permissions. This will be fixed in GAP 4.8.3. In 
the meantime, please use the following fix to make all package files 
world-readable:

cd gap4r8 # or whatever the name is
chmod -R a+r pkg

(we suggest to call it on the whole 'pkg' subdirectory rather than on 
individual packages involved, just in case).

Apologies for any inconveniences,
Alexander

P.S. The help system reads information about known help books,
including package manuals, so this is an instance of the same 
problem with permissions. Calling `chmod -R a+r pkg` on the whole 
pkg directory should fix all problems at once.

When I started, I got the error that /usr/local/gap4r8/pkg/PolymakeInterface/PackageInfo.g is unreadable or does not exist (notice that it is a new package). However, the file does exist, but I found out that most files are owned by 50009 whoever that is (this was never a problem in previous versions). So I made this particular file readable for group users. Now I can start GAP and also the packages load, but the help system is broken:
