Server: Error 500 after updating NC 16 to NC 17 r2

[petrk94]

Hello,
Im facing a bug from my NC 16 updated to NC 17 r2 instance.
After a successful updating process, it wanted to load the web interface and caused the Error 500.
No access is possible.
In the php error log, I got this information:

[Mon Sep 30 11:40:59 2019] [warn] [client 94.223.33.225] mod_fcgid: stderr: PHP Fatal error: Declaration of OCA\GroupFolders\Versions\VersionsBackend::getVersionFile(OCP\IUser $user, OCP\Files\FileInfo $sourceFile, int $revision): OCP\Files\File must be compatible with OCA\Files_Versions\Versions\IVersionBackend::getVersionFile(OCP\IUser $user, OCP\Files\FileInfo $sourceFile, $revision): OCP\Files\File in /var/www/virtual/petrk/nextcloud.xxx/apps/groupfolders/lib/Versions/VersionsBackend.php on line 37

I hope you can help me to restore it to bring it back to work.

Probably a better way, but:
sudo mv /var/www/virtual/petrk/nextcloud.xxx/apps/groupfolders /var/www/virtual/petrk/nextcloud/apps/groupfolders.old
Then you can proceed and it gets reinstalled from what I see. I'm still looking. Probably can delete the newly created ".old" folder after the upgrade.

[kesselb]

Probably can delete the newly created ".old" folder after the upgrade.

Yes.

cc @nextcloud/server-triage the issue itself is already fixed by groupfolders 5.x.

[skjnldsv]

@kesselb so I'm guessing we just did not released groupfolders on time?

[kesselb]

Hmm. I don't think so. 5.0.0 (with the relevant changes) is out for 25 days.

Hi @kesselb @skjnldsv

Users are running into this issue when updating to NC17 stable.
https://help.nextcloud.com/t/web-updater-from-nc-16-0-4-to-17-doesnt-work-with-group-folders-use-command-line/61110
This issue arises when group folders app was enabled before the update.

The big issue is, that group folders app in version 5.0 is not compatible to NC16 and therefore users cannot update to group folder 5.x before updating to NC17. In return all users who didn't disable the app before the update, will get stuck in HTTP 500.

For users without ssh access this may become a serious issue.

[petrk94]

@Schmuuu
how I can solve it?

[Schmuuu]

I posted a warning in the forum:
https://help.nextcloud.com/t/nc17-update-disable-group-folders-app-before-performing-the-update-of-your-server/61112/2

To solve the issue:

• login to your server via ssh
• run the occ command “upgrade”:
  sudo -u <web user> php /path/to/nc/occ upgrade

Here the log (system work now, issue solved by this solution):

I suppose there are plans underway for Group Folders to be supported in NC17 by the time of the official release, right? Our use case certainly depends on GF working :-\

[Schmuuu]

@gwolf The groupfolders app is supported in NC17 already. The only issue here is, that the groupfolders app in version 5.x is not compatible with NC16 and in version 4.x is not compatible with NC17. So in a way an upgrade path is missing.

The workaround therefore is:

• disable group folders app
• update NC from 16.x to 17.0
• check that group folders app has been upgraded to version 5.x (if not, update manually)
• enable group folders app again

[gwolf]

OK, got it. Thank you very much!

[DaCryptor]

To solve the issue:

* login to your server via ssh

* run the occ command “upgrade”:
  `sudo -u <web user> php /path/to/nc/occ upgrade`

Great "workaround" for a lot of people running NextCloud in a shared-hosting environment...

To be honest, I see the NextCloud-team releasing more and more features very fast, but also more and more errors occur (even in the basic functions), and I am losing trust in the quality of this software.

[kesselb]

  'app_install_overwrite' => 
  array (
    0 => 'groupfolders',
  ),

Do you have something like above in your config.php?

[Schmuuu]

No. I only saw this getting added:

'app_install_overwrite' => 
array (
0 => 'tasks',
1 => 'files_readmemd',
2 => 'polls',
3 => 'apporder',
),

[kyrofa]

The only issue here is, that the groupfolders app in version 5.x is not compatible with NC16 and in version 4.x is not compatible with NC17. So in a way an upgrade path is missing.

Wait, that's the exact reason we in the snap held off on the upgrade to v16, because the calendar app did the same thing. However, that situation was fixed with #16507, where Nextcloud now disables incompatible apps before the upgrade, and updates them/re-enables them afterward. Did that break?

[kesselb]

where Nextcloud now disables incompatible apps before the upgrade, and updates them/re-enables them afterward. Did that break?

For me it works :confused: 16.0.5 with groupfolders 4.x to 17.0.0 will disable groupfolders during upgrade. I can reproduce the fatal error OCP\Files\File must be compatible with OCA\Files_Versions\Versions\IVersionBackend::getVersionFile with "enable untested app". We have to dig deeper :see_no_evil:

[My1]

curious question regarding this: is the possible to knock out an app without a commandline, like in the database or some config file and could that help shared hosting users?

@DaCryptor Im running my NC instance on a shared host, the whole thing worked too without need of sudo. Just php /path/to/nc/occ upgrade and it worked

[jthacker48]

I posted a warning in the forum:

I must be making a mistake when trying to run the command as I'm getting "can't open web: no such file".

I'm running NC as Docker in Unraid. I'm putting in the following (exactly):

sudo -u php /config/www/nextcloud/occ upgrade

I'm sure it's something dumb so I apologize in advance.

[tigernero79]

in my opinion, "occ update" does not handle apps to be updated well, with a web-based update, the check of the group folder version is not done or updated. reason why we have error 500. on systems where we have access ssh we solve with command via terminal "occ upgrade", the verification is done because it is successfully updated.

[rschr]

The malfunction reported in this issue just happened to me in trying to upgrading from 16.0.6 to 17.0.1 through the browser-based upgrader. Reloading the web page in the browser to complete the upgrade left me with a http 500 error and the above mentioned PHP error connected with group folders in the logs. (Performing occ upgrade on the server's command line finished the job, though.)

[moritzps]

Probably a better way, but:
sudo mv /var/www/virtual/petrk/nextcloud.xxx/apps/groupfolders /var/www/virtual/petrk/nextcloud/apps/groupfolders.old
Then you can proceed and it gets reinstalled from what I see. I'm still looking. Probably can delete the newly created ".old" folder after the upgrade.

This is the only way I found to fix it on a shared hosting without SSH access (I only have SFTP access). I'm still uncertain how to proceed now, because I can not update groupfolders from the NC17 web-based app updater and am afraid I'd loose the files I have in my group folder when removing the app and reinstalling it via the app store.

[ph00lt0]

Just updated on the stable channel and had to disable the group folders manually. To be able to update the installation. It was complaining about integrity of the update.secret.

[DudeBroChill]

My NC is also on shared hosting with no ssh access. I was able to finish the upgrade by using ftp into my server and going in to the apps folder and renaming the folder “groupfolders” to “STOPgroupfolders”. I then reloaded the NC page and the installation continued... then it warned me about all the incompatible apps.

[kyrofa]

We have to dig deeper

@kesselb any progress here?

[kyrofa]

I'm noticing something interesting that might be related. If I install Nextcloud 16.0.5 with version 0.13.0 of the Right click app, and then try to update to v17 (based on the daily tarball), the update log looks like this:

And NOW it works! What... ? So I try doing it a third time:

Nextcloud is already latest version

Why didn't that happen the second time? Why didn't the first upgrade take despite seemingly encountering no errors? Basically, something about the app update process during an upgrade does indeed seem broken.

[kyrofa]

The above actually happens from 16.0.5 to 16.0.6 as well; perhaps some breakage was backported.

[kyrofa]

Given that v0.13.0 of files_rightclick supports v17, I'm not sure why it's forcing the update to happen before continuing. Note that the first upgrade updates it to 0.14.2, and only the second gets it to 0.15.1. Let me know if this isn't pointing in the right direction (I can't duplicate any issue for groupfolders), and I can log an issue on its own, but it sounds like the root issue might be the same.

[ph00lt0]

I tried to do some investigation on it. If you run the web updater from 16 to 17 you get the empty page. After this I revisit the updater page, this page complains about the integrity as well and suggests entering the plaintext value of the updater secret. (hashed version stored in the web.config file).
When updating the update secret and entering the plain text value as well it response with: Token invalid. Would this mean that the groupfolders somehow use a different key?

[kesselb]

cc @nextcloud/server-triage

https://github.com/nextcloud/server/pull/16145 regarding the files_rightclick app. Probably the updater is confused somehow because it's shipped. I don't know if updating shipped apps via appstore is possible.

As workaround for the snap update I would suggest to remove the groupfolders app and install it after the update. occ app:remove --keep-data groupfolders will remove the app but keep the (user)data. If the app was installed $? = 0 and if not 1.

Do you know if there is a possibility to keep the data when using the web UI? I do not have ssh access and would like to update the groupfolders app but can’t because it requires NC16 to be updated (which does not make any sense). See screenshot above.
I‘m afraid if I delete the app now and reinstall afterwards all data is gone.

[skjnldsv]

I don't know if updating shipped apps via appstore is possible.

@kesselb It is not possible because of file integrity check

[DudeBroChill]

I have not received any negative repercussions from just renaming the groupfolders folder using ftp and then finishing the re-stall. Worked perfectly, and then groupfolders just installed its self afterwards. I’ve had zero data loss. This seems to be the easy around around this.

sudo mv /var/www/virtual/petrk/nextcloud.xxx/apps/groupfolders /var/www/virtual/petrk/nextcloud/apps/groupfolders.old
Then you can proceed and it gets reinstalled from what I see. I'm still looking. Probably can delete the newly created ".old" folder after the upgrade.

This is the only way I found to fix it on a shared hosting without SSH access (I only have SFTP access). I'm still uncertain how to proceed now, because I can not update groupfolders from the NC17 web-based app updater and am afraid I'd loose the files I have in my group folder when removing the app and reinstalling it via the app store.

Also resolved my issue.

Hi,
I have the same issue but now Im stuck because Im not able to do php occ upgrade.

I only get this error:

An unhandled exception has been thrown:
Exception: Environment not properly prepared. in /cloud.*******.**/lib/private/Console/Application.php:166
Stack trace:
#0 /cloud.*******.**/console.php(96): OC\Console\Application->loadCommands(Object(Symfony\Component\Console\Input\ArgvInput), Object(Symfony\Component\Console\Output\ConsoleOutput))
#1 /cloud.*******.**/occ(11): require_once('/cloud.*******....')

Does anyone know how to resolve this without data loss?

@AstroGD please give us the logged json error in your nextcloud log file. We're missing info on your comment

I don't know where the log file is located. But I figured out how to solve the update issue myself:
I reinstalled the backup created by the updater and then followed the steps on this issue by deactivating group-folders, updating and the re-enabling the plugin after installing the newest version of it. So far there are no issues and I installed another update without issues today. Maybe the logfiles are still there - If so I would happily send them to you after I know where they are located.
