thanks @bb77 this was in the snap install test
itās deleted already - it was just to illustrate how any install brings error messages straight after install
If you donāt mind, my two last posts from this morning show the errors i get from the actual running NC that we use but is buggy ā¦
iād be more than happy to understand and fix it
though iām ready to reinstall in another way, and iāll try AIO today
thanks i appreciate a lot your concern
Just to mention also a simple an easy way to run NC is Nextcloudpi.
It is possible to run it on many ARM- and x86 devices.
The installation can be done with the image (for RPI), docker or a curl installer script.
The docs are here: https://docs.nextcloudpi.com/
In what way is it buggy? Are you still having an actual problem, or are you just bothered by the log messages? Production systems are almost never completely free of any warnings. Youāll always have background port scans and access attempts on the internet that generate some.
Of course to be fairā¦ I spent yesterday removing a customerās dead domain controller from Active Directory, seizing FSMO roles, building a new DC, and doing an authoritative sysvol restore on another oneā¦ so I may be a little numb to log errors at the momentā¦
The ones related to SQL above are what would concern me. Did you say what your database is and how itās configured?
hi @KarlF12, thanks for asking
buggy; i find many fatal errors in the logs:
typically:
On another hand, do you mean I shouldnāt worry about the errors ou fatal errors ?
I use Mariadb latest, apache2 latest, php 8.1, ubuntu 22,04
So far I understand that file locking blocks edition or deletion.
Plus the log about the doubled primary key ā¦ i donāt understand this one, but thought it was file locking too.
Do you have a TURN server set up and configured correctly?
no, iāve discovered recently that it was very necessary, but then iām surprised that it happen to run many times without it ā¦ 
hi, i think iām getting somewhere:
some of the main problems i face are: MySQL exception, database lost, unable to open/edit/rename a .md file - same with Collectives.
I have removed Everyone Group and Collectives, and open a file or edit it is now possible.
Could it be an issue?
about Talk and coTURN, iāve followed these steps:
but iāve added both DCP and UDP for STUN and TURN
iāve installed AIO
it a nice automatic way to install NC 
Activity app widget wonāt show anything though . . again:
The first logs after few minutes of usage:
Error no app in context OCP\Files\NotFoundException: 2022-08-29T02:46:56+0200

Iām still questioning the stability of nextcloud coz iāve been though so many installs. yet the same error right after install. But I donāt find an answer to these OC logs.
Does it make sense to anybody?
Not sure what your issue is there. I have a production AIO and a production Docker system and they both show activity in the dashboard widget.
I still get the sense that youāre in search of an answer to a nonexistent problem.
I get minor little warnings in my logs sometimes, and yet I donāt experience any actual problems. My docker instance has been running since Nextcloud version 16 I think and has always been stable.
This seems to be caused by the maps app. You can try to disable it and see if it fixes the issue.
haha then you are more than welcome to follow me in my delusional quest ^^
but look close, right after install, i get a FATAL ERROR
Text and Collectives wonāt open the files to edit them
At this very moment, I have 4 different installs:
none of these 4 is working properly
they all give errors and fatal errors few minutes after few apps are installed
(all tested app since we removed Community Document Server and ONLYOFFICE)
iām afraid that without a clear answer, all this work will have been useless
because our teams should not be given this tools any longer in production.
Does it make sense to every one here? I wish i found the problem.
I have shared many logs here on the forum, so far Iām only getting answers that try to make me chose another option. So far, iāve managed to install NC in every way. But as soon as it starts working: fatal error
and i donāt get solution to these mains OC / OCD / DB errors.
Who knows what is it about?
Who has experienced them?
Whoās got a solution?
please . .
ha ha the manual install the IT man did yesterday, is off line this morning . .
iām afraid I wonāt be the only one with a problem ^^
I think the errors are likely caused by some of the additional apps that you are installing all the time but did not inform us about. As you can see by looking at the logs, you may be able to find out which one is causing the issue.
thanks @szaimen
looking at the errors, I have uninstall Everybody group and Collectives.
Same problems. See, the instance installed yesterday by an ingenior is off line this morning.
Can i really uninstall Text app? What are we going to do without this app in NC?
I thank you for your answer. May I ask you an advice?
Do you have a solution to correct these errors?
So you do not have the maps app installed? Based on the logs you provided the issue seemingly was caused by this appā¦
oh, it seems that i didnāt get to read one of your messages, sorry.
Yes it is disabled and removed.
On my main NC install - the one that iām really tryin to get to function properly - the three EverybodyGroup, Collectives, Maps are removed, the server rebooted.
Look at a .md file when I try to open it:
I come to think that the problem is not the apps, but the cache system.
Coz now iām reading that MindMap has a problem.
All these app where included in OCP errors.
Without knowing what this person did or didnāt do or what he knows about Nextcloudā¦ there is really nowhere to go with this.
Itās a text editing app for use in the web browser. Nextcloud itself can work without this function.
Too many questions about thisā¦ What is this file? Was it created on Nextcloud or uploaded to it? Created with what program? Are you unable to open any text files at all in the browser?
Well look, I think itās also fair to say that many of us have looked at this and still arenāt clear on what symptoms youāre having other than some log entries that may or may not indicate an actual problem. Weāre also 35 posts deep and have yet to see the Nextcloud and web server config files, and really have no idea which symptoms are from which of your 4 installs.
I can just imagine the kinds of errors that must be in Google Driveās server logs, while the user experiences no problems at all.
If weāre going to continue this then letās troubleshoot a visible problem that you experience rather than chasing random log entries.
He installed the manual way, with nextcloud recommandations
Text app is part of our working process. We donāt use nextcloud as a simple file sharing, but a collaborative platform
itās a simple text.md file created in nextcloud
yes unable to open text.md files, created in nextcloud
server settings in post 15
nc conf about cache in 16
I can just imagine the kinds of errors that must be in Google Driveās server logs, while the user experiences no problems at all.
