unable to create directory '/nonexistent/.cache/dconf': Permission denied.

[guofengzh]

When uploading file, the logs on the console shows:

(process:15426): dconf-CRITICAL **: 14:06:22.660: unable to create directory '/nonexistent/.cache/dconf': Permission denied.  dconf will not work properly.

OpenMeetings 7.1.0, full image.

But the file is uploaded and converted successfully.

What is the problem? Should it be fixed?

Hello @guofengzh

Could you please tell me what were your steps?

I've just built full version locally and can't see this error :(((

The error itself caused by the fact user nobody has no $HOME, it can be fixed

But I need steps to reproduce first :)

[guofengzh]

Select "My conference room (for 1-16 users)" to enter the room, then in the file tabe, click the up arrow to upload a PPT file. The file load successfully and can be dropped to the whiteboard. The content on the whiteboard has no problem.

Using "sudo docker logs omc", see the two lines:

(process:50467): dconf-CRITICAL **: 13:01:06.819: unable to create directory '/nonexistent/.cache/dconf': Permission denied.  dconf will not work properly.

(process:50482): dconf-CRITICAL **: 13:01:07.338: unable to create directory '/nonexistent/.cache/dconf': Permission denied.  dconf will not work properly.
ubuntu@ip-172-31-10-173:~$

omc is my container name. I build my own image.

I use the 7.1.0 tag, and made some changes to the Dokerfile:

1) I have add the following lines for Chinese fonts at the front of the Dockerfile:

ENV OM_FONTS=/usr/share/fonts/chinese

# Chinese Fonts 

RUN apt-get install -y --no-install-recommends \
    ttf-mscorefonts-installer \
    fontconfig

RUN mkdir ${OM_FONTS}

WORKDIR ${OM_FONTS}
COPY fonts/*.* ./
RUN chmod 755 *.TTF
RUN chmod 755 *.ttf
RUN chmod 755 *.ttc
RUN mkfontscale
RUN mkfontdir
RUN fc-cache -fv

2) I also add "hkp://keyserver.ubuntu.com:80" for the keyserver, because the key servers in the origial Dockfile does not work (connection failed) when build it in a AWS VM in Korea region.

I do not modify any other part of the Dockerfile.

Hello @guofengzh,

Thanks for the detailed steps I was able to reproduce (and hopefully fix the issue)

I've added additional keyserver, not sure about the fonts :( Could you please advise shall I add your # Chinese Fonts to the Docker file? :)

[guofengzh]

Hello Solomax,

Your fix works well here. The issue resolved.

I think you do not need to add the fonts to the dockerfile because it is specific to different languages.

I close this issue..

Thanks for your help very much.

[solomax]

Great! Thanks for verification!
