Collabora Online stopped working after upgrade firmware to 6.9.3 and newer

[pl_shibby]

I`m currently using firmware 6.9.2 on my Readynas Pro4.

Everything works fine. I`m using Owncloud 10 with Collabora Online 6.0. But after upgrade ReadyNAS firmware to newer version (6.9.3, 6.9.5, also tested 6.10), Collabora Online stopped working. After back to 6.9.2 everything works fine once again.

I tried restore NAS to factory defaults and fresh install owncloud with collabora = the same result

I tried install Collabora in docker instead *. deb package = the same result

I tried different ReadyNAS device(for example RN102) = the same result

I think something has been changed in kernel between 6.9.2 and 6.9.3...

What else i can do to use latest firmware and have working Collabora Online?

FYI update to OS 6.10.1 doesn`t help.

So... i installed PHP7.0 and migrate owncloud 10 to nextcloud 12, then 13->14->15.. then i have to upgrade php to 7.2 (nextcloud 16 is not supported by php7.0). After PHP upgrade i`ve installed nextcloud 16... Now Collabora online works!!

Hope this may help someone.

Best Regards.

The release notes say there was a security update to the kernel that might be getting in your way.

Is Collabora up to date?

FWIW, 6.10.x upgraded apache2, so there are more changes as you upgrade to current firmware.

Yes, Collabora Online is updated to latest version

collaboraoffice6.0                           6.0.10.29-292                     amd64        Brand module for Collabora Office 6.0 -29

but on older version was the same.

So why after switch from 6.9.2 to 6.9.3 (rule od small step, Collabora stopped working?
This is the log:

and after back to 6.9.2 Collabora back to life.

I am in vicious circle. I cannot switch to latest OS6 firmware because Collabora stopped working BUT i cannot install latest ownCloud because 10.2.x doesn`t support PHP5.6 whitch i currently using. Sure, i can install PHP7.x in jessie but this is solution for very short time because ownCloud developers already said that PHP7.0 will be also no supported soon. The best way is install PHP7.3 but this require Apache 2.4, so i have to upgrade ReadyNAS firmware to 6.10.x 😉

So this is a big problem for me: have older OS6 and older ownCloud but working Collabora Online OR have latest firmware with latest ownCloud but without Collabora Online.

Best Regards.

Yes, Collabora is up-to-date (6.0.10.29-292) but on older version was the same.

So why after upgrade to 6.9.3 Collabora stopped working and after back to 6.9.2 back to life? Here is the problem.

This is a big problem for me. I cannot use latest OS6 firmware because Collabora doesn`t work. BUT i have to upgrade firmware because the latest ownCloud doesn`t support PHP5.6... The best way is install PHP7.3 for future owncloud releases but for that i need apache2.4.

Best Regards

i don`t know why but each time i put some code in "code tag" (logs for example) my post has been deleted.

In attachment is a screen with an error from loolwsd service. On 6.9.2 this error doesn`t appear

There's an automatic spam filter that is triggering for some reason.  Mods will generally check the quarantine and eventually release false positives - but not always, since the real spam can be overwhelming.  If you PM me or one of the mods we can release it for you.

It's not something I use, so I can't help with debugging the application.

I am seeing several hits when I google for "loadcomponentfromURL returned an empty reference" that might give you some clues.  They are mostly with older versions of Collabora.

i`m trying to fix it from an year. I readed a lot of threads, tried to implement any solution i found. Posting here is my act of desperate 😞

[StephenB]

I guess you could try moving forward to 6.10.1 (which would upgrade apache).  It's conceivable that would behave differently.

The main problem there is that you can't downgrade back to 6.9.x.  But if you are really stuck, that might not matter much.

[pl_shibby]

i am able to back from 6.10.x to 6.9.x 😉 Already did it once. This is not a problem for me.

For week or two i should have readynas 102 "for fun". I will try install fresh 6.10.1, latest owncloud and collabora and we will see whats happened. Will let you know.

i will try also compare sources 6.9.2 and 6.9.3 and see what has been changed in kernel. Once i compiled kernel for readynas - needed module for mellanox 10GbE card 😉 Should not a problem to compile whole kernel.
