External Storage also allows users to share files stored in these external locations. In these cases, the credentials for the owner of the file are used when the recipient requests the file from external storage, thereby ensuring that the recipient can access the shared file.\n\nExternal Storage can be configured using the GUI or at the command line.

            "description": "This application enables administrators to connect ownCloud to an LDAP-based user directory for authentication and provisioning users, groups and user attributes. Admins can configure this application to connect to one or more LDAP directories or Active Directories via an LDAP interface. Attributes such as user quota, email, avatar pictures, group memberships and more can be pulled into ownCloud from a directory with the appropriate queries and filters.\n\nA user logs into ownCloud with their LDAP or AD credentials, and is granted access based on an authentication request handled by the LDAP or AD server. ownCloud does not store LDAP or AD passwords, rather these credentials are used to authenticate a user and then ownCloud uses a session for the user ID. More information is available in the LDAP User and Group Backend documentation.\n\n",

When a file is deleted from a share, it can be restored in the same manner, though it is no longer shared. By default, these files remain in the trash bin for 30 days. To prevent a user from running out of disk space, the ownCloud Deleted files app will not utilize more than 50% of the currently available free quota for deleted files.

Running one privacyIDEA server in your network enables you to add second factor not only to your ownCloud installation but also to any other application like web portals, firewall, VPN, Windows Desktop login, SSH servers...\n\nThe privacyIDEA ownCloud Application runs in a demo mode after download and installation. You need a working privacyIDEA installation and a subscription file provided by NetKnights for productive use.\n\nNote: After activating the App *all* users will be verified with a second factor.

#### Browser log

[tschiu]

Cloned tree under /var/www/owncloud/apps as "tasks". Clicked "activate". Owncloud states that an upgrade is necessary. Screen goes to maintenance screen with info that Owncloud is upgrading to 9.1.5 (which is the current version I'm running). Starts performing database check and fails on step 5 of 24 (I think that's table oc_filecache) with an error on the maintenance screen. Attempts to access owncloud after the error appeared hung. Restarted apache2. Then got standard maintenance screen. Moved tasks out of apps and now Owncloud is working again.

And based on the reports on the app page and the duplicate issue filed directly above, this critical issue appears to be affecting everyone. Seems high in urgency and importance.

[sggalan]

Not a tasks app issue, but a lot of apps one.
Also, not an owncloud or app code issue, but a big apps.owncloud.com site problem.
This is happening with a huge lot of apps and even when clicking the 'download' button in the app info page. Has apps.owncloud.com site been hijacked? O_o (Just navigate in the site an try to download any app, the most of them are returning Error 400 )

[sggalan]

I've been wandering along forums and groups, and no one has noticed this apps.owncloud.com problem. Is it me the only one having the "global" problem? Or is it me the first one to notice it?

[jancborchardt]

@torstenbunde @arkadiuszzolnik @tschiu @mach-o @sggalan just for your information (since no one from Owncloud bothered to reply here and they removed the notice the maintainers of this app moved):

This app and its maintainers moved to https://github.com/nextcloud/tasks – you can also install that within your Owncloud and it should work. If there’s any issue please feel free to open it in the issue tracker there and we will be very happy to help. :)

[mach-o]

@sggalan : I'm not experiencing a broader issue: calendar, contacts, and documents apps enable fine for me, it's only tasks that has caused a problem, and @jancborchardt's explanation of the problem seems to make sense.

@jancborchardt : They removed the notice and left a broken app in place? If true, that is dreadfully counterproductive. I'm hoping to see Nextcloud packaged for my distro in the near future: I'm too spoiled these days to sully my hands with repository cloning and the like ;)

[torstenbunde]

@jancborchardt : I just updated ownCloud to version 9.1.6 and used the tasks app from the Nextcloud repository you mentioned. Result: Same problems as described above.

I also tested the tasks app with the ownCloud version 9.1.5.2 I used before: No improvement compared to the previous app version.

So I think I'll check some things in the next days and will open it in the issue tracker at there.

[sggalan]

@mach-o: yes, if you use the standard calendar and contacts apps there's no problem, but when using the 'plus' versions (they're third party, but very commonly used) these ones are not preserved in nextcloud. In fact, I found my old contacts list when reactivating the old native apps after upgrade :-) so you're right about these ones.

[sophieforceno]

I'm running into the same issue (same error) when updating Notes app to 0.9.4 from 0.9.3. Originally cloned the repo from here and copied into apps/ to install. I'm running ownCloud 9.1.6.

[jancborchardt]

I'm clueless then - maybe try with Nextcloud. cc Tasks app developers @raimund-schluessler @Henni

[sefernet]

in Fedora 27 Im tried "Nextcloud" 10.xx , same error : "404" ... No Task neither

[dlandon]

Once tasks is uploaded to the Marketplace, try again and report back if you have an error.
