Duplicate of #19674

alex9434 commented 4 years ago

Hello @kesselb, the referenced issue #19674 has been closed by you without an actual solution. The user has just been told to install the app manually. This is not a satisfactory solution, because it would require MANUALLY updating all apps individually. Because of this bug the automatic update is broken.

kesselb commented 4 years ago

19674 is still open? I closed this report as duplicate. It's not necessary to have multiple issues for the same problem and also does not speed up resolution. Please use the search before creating a new issue the next time.

I have same problem with News app. Ubuntu 20.04, Nextcloud 20.0.6

The PHP error is always the same:

Invalid argument supplied for foreach() at /home/myuser/web/nextcloud.mydomain.com/public_html/apps/serverinfo/lib/OperatingSystems/DefaultOs.php#158

On the line of that file the foreach() is applied on a supposed array of network interfaces file-settings retrieved a couple of lines above with:

public function getNetworkInterfaces() {
                $interfaces = glob('/sys/class/net/*');
                $result = [];

                foreach ($interfaces as $interface) {

I suspect that it could be a problem of "user/group permissions" to access to that /sys/class/net content files... but i unkonw why this was no problem with previous versions of Nextcloud. I've Nextcloud 18.X installed on another VPS with less permissions and it not seems to be a problem.

Indeed, another clue: when i go to Settings > System it seems that the PHP script cannot get information neither about RAM and obviously about network interfaces (appears in blank that section).

Please, some kind of help to users like me less experts in the deeps of the linux sysadmin? I understand that if there is a problem of permissions to access RAM/networks interfaces of the server then it is not possible to shown in System section. But it should NOT imply a PROBLEM TO INSTALL/UPDATE an app, it should?

i'm suggesting that probably there is an unnecessary call to the method ->getNetworkInterfaces() when installing/updating an app. Certainly i have been able to install apps (like calendar, for example) without this problem, in the same Nextcloud instance and server, the same day. So, i conclude that some apps are requesting this "network interfaces" info without needing it.

Thanks in advance!

I did a re-install of Nextcloud and now the problem seems to be gone.
