Hi all!

I see this while the maintenance:repair command runs

- Rebuild font library
     - WARNING: Error while trying to rebuild fonts, if you had any custom fonts configured you'll need to run `occ documentserver:fonts --rebuild`

sudo -u www-data php /var/www/nextcloud/occ documentserver:fonts --rebuild

What would you suggest I´d do? Peace!

Adding info so the bug doesn't get closed for inactivity. 3 months later and my 2 NC server instances have been updated to 27.1.1 / 25.0.12 Issue is still the same. Also tried adding some fonts manually with the occ documentserver:fonts --add command and the fonts seem to be added, but then during the rebuild, I get the same error. Once added, the command occ documentserver:fonts lists the installed fonts but then immediately proceeds with spitting out the exact same error and if you try to print the documents, they still show up blank. I also built a third NC Server from scratch, which is also 27.1.1 now and the issue is exactly the same. Related issues #278 and #251 also see no progress. I also found several other related issues, even older than these, but nobody seems to be able to come up with a workable solution.

[janisstreib]

Same here. The segfault seems to happen in apps/documentserver_community/3rdparty/onlyoffice/documentserver/server/tools/allfontsgen executed in apps/documentserver_community/3rdparty/onlyoffice/documentserver/server/FileConverter/bin. The binary seems to originate from the ONLYOFFICE project.

I've tried Manually updating the files from their latest release but the segafult seems to persist. According to dmesg , the segfault happens in libgraphics.so .

[cernst72]

Same here using the official docker image nextcloud:28.0.1-apache

$ docker exec -u www-data $(docker ps -q -f name=cl_cloud.1) php occ  documentserver:fonts -v
No fonts added

Hello got the same here NC7 28.0.2 Any idea?

[robwmi]

Same here on 28.0.4 FileConverter is also faulting on creating previews for files. I'd be interested in helping to address this issue, but haven't quite figured out where to start yet. If anybody with some background with these processes could get me started in the right direction that would give me a big leg up on this. Thanks for your notes @janisstreib - you've made if further than I have so far!

Actually, I'm getting

allfontsgen[28257]: segfault at 8 ip 00007f7f8c81c4e0 sp 00007ffc9e894da0 error 4 in libUnicodeConverter.so[7f7f8c800000+37000]

That likely being this guy: /var/www/nextcloud/apps/documentserver_community/3rdparty/onlyoffice/documentserver/server/FileConverter/bin/libUnicodeConverter.so

Same on 28.0.5, issue being more than 1 year old now... At least, is there any workaround to this? What are the impacts of this failure with ONLYOFFICE usage?

[susobaco]

Same problem, Debian 12 Nextcloud 28.0.5 OnlyOffice 9.2.0 Comunity Document Server 0.1.17

[zsiga19]

Same problem, docker container Nextcloud 29.0.4 Community Document Server 0.1.18 OnlyOffice 9.3.0

[Albirew]

I believe it's not linked directly to NxC version, but of the difference between documentserver app and onlyoffice client app:

• NxC server app (Community Document Server 0.1.20) is stuck at OnlyOffice document server 7.2.x (see #312 )
• NxC client app (ONLYOFFICE connector 9.5.0) is at the latest version of OnlyOffice 8.2.1, without any way to choose lower versions

So I believe this issue depends on #312

If you really want to use OnlyOffice and can run a docker container, you can check here
