[Freedombox-discuss] Mediawiki - no access rights for images

[permondes - sagen]

Changing the subject of the mail as I think this is an access right
issue introduced by Plinth 0.35.
Read access to the mediawiki should be available for anyone. Even
logged in to mediawiki the images are not visible.Checking some
directories:
> @freedombox:/var/lib/mediawiki$ ls -al 
> ...
> drwx------ 1 www-data www-data 106 Jul 22 17:06 images
Is it correct that the owner of the images folder is "www-data"? And
only the owner has access, not the group, nor anyone else?
For the individual images rights are:
> @freedombox:/var/lib/mediawiki$ sudo ls -al images/0/01
> insgesamt 36
> drwxr-xr-x 1 www-data www-data    44 Jun 21 20:58 .
> drwxr-xr-x 1 www-data www-data     8 Aug  2 21:07 ..
> -rw-r--r-- 1 www-data www-data 32863 Jun 21 20:58
> Fadenbild_genagelt.jpg
which looks okay.
Checking https://www.mediawiki.org/wiki/Manual:Configuring_file_uploads
:

So the rights of the 'images' folder are set wrong, am I right? Should
it be drwxr-xr-x?Was there an change on this in Plinth 0.35?Is it save
for me to try this change?
Thanks for your help   Dietmar
