Nextcloud 10.0.1 on Ubuntu 16.04, java 1.8.0_111
####I ’ve installed it like this
apt-get install tesseract-ocr tesseract-ocr-deu tesseract-ocr-deu-frak tesseract-ocr-eng tesseract-ocr-equ tesseract-ocr-osd
cd /var/www/nextcloud/apps
git clone https://github.com/janis91/ocr
chown -R www-data:www-data ocr
sudo -u www-data php /var/www/nextcloud/occ app:enable ocr
The output of the last line wasocr enabled
sudo -u www-data php /var/www/nextcloud/occ app:list|grep ocr- ocr: 1.0.0
But unfortunately now the hourglass runs forever on “Enabled Apps” in the apps settings.
I only can do asudo -u www-data php /var/www/nextcloud/occ app:disable ocr
This will bring back the “Enabled apps” page.
On the “Not enabled apps” page, now i have this:
Actually this is a weird behaviour, as it doesn’t come up for me, but it does for some other users. Are you sure that you have the latest nextcloud version installed?

Isn’t 10.0.1 the last version at the moment?
I think it is. But the problem is that I cannot reproduce the bug with my clone of the latest stable10 version from github/nextcloud.
Maybe I will give it one more try tomorrow. Sorry that I cannot help you atm.

Now I tested this weird thing and I assume this bug comes up because of the following:
Initially there has been a bug report for my ocr app 20th Sept which came up with the same behaviour.
After this i figured out, that my info.xml was likely newer than the nextcloud interpreter for the info.xml, although the official XSD file specified multiple language options as a possible solution.

### Steps to reproduce
1. Install for example the next notes app from the appstore. (An app with language attribute and multiple name tags in the info.xml is required)

Enabled site shows loading state forever.

no
**Where did you install Nextcloud from:**

#### Recommended Solution
I would recommend to change the necessary lines of code, which read the info.xml, because the defintion changed in some points [(info.xsd)](https://apps.nextcloud.com/schema/apps/info.xsd).
The reason of this specific bug is the following: in lines 203 and 204 (also 238/239 and maybe other lines as well) of the AppSettingsController.php (method: listApps) the tags of the info.xml are read.
```
$apps = $this->getInstalledApps($includeUpdateInfo);
usort($apps, function ($a, $b) {
$a = (string)$a['name'];
$b = (string)$b['name'];
if ($a === $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
});
```
The new name tag's max occurrences number is unbounded as of the info.xsd:
`<xs:element name="name" type="l10n-string" minOccurs="1" maxOccurs="unbounded"/>`
Because of this the method has to be changed in a way, that supports multiple name tags. (l10n support)
_Maybe there are other occurrences and other interpreted tags as well, which have to be changed._
After this issue was fixed, tested and approved for NC10.0.1 I didn’t expect that this would still be a problem.
But I guess the problem is likely that the downloadable version of nextcloud from Download and install Nextcloud
2016-09-28T13:31:28+00:00 12ec1d1e3e5d90140e2afaca8afc3727dadeca1a
and this is kind of old. It might be one of the first 10.0.1 stable versions, but there have been a few backports and transifex-updates after that date. I guess that this is the reason, why many people still recognize this issue. The bugfix isn’t available in the download build. only in the stable10 git-branch it is available.
Maybe it is somone here, that can give some more information regarding this?@LukasReschke I don’t know if you are the right person to contact. but maybe you are a good start point?

Maybe it is planned to bring the 10.0.2 RC in to the downloads page after it is tested successfully. If this is right, I would suggest to wait for this update and just update nextcloud. Then it should work, I guess.
