NC 27 > 28: No files showing (common solving steps tried)

ℹ️ Support
,
1

Hello,

I have just updated to NC 28.0.5.1 from NC 27.

I get a “No file” message on the file tab. But, if I use the favorites button, I can see them (at least all the folders in which the favorite folder is).

I did some operations:

  • files:scan -all
  • maintenance:repair
  • files:cleanup
    In /var/local/nextcloud-data:
  • find my_user/ -type d -exec chmod 750 {} ;
  • find my_user/ -type f -exec chmod 640 {} ;

with no success.
This is specific to my user. I have another user, which can access its files normally.

I tried something: I have created a folder and file on the filesystem, then did files:scan --unscanned --all. I get 0 folder and 0 file in the summary…

I would be grateful for any idea! Thanks.

Hey, please check your nextcloud.log - any errors/exceptions there?

3

I have many exceptions like:
ConnectException cURL error 52: Empty reply from server (see libcurl - Error Codes) for https://wyqu84.a4.swdrive.fr/ocm-provider/
error while discovering ocm provider

And errors like:
ConnectException cURL error 52: Empty reply from server (see libcurl - Error Codes) for https://wyqu84.a4.swdrive.fr/public.php/webdav/Readme.md

These sound like you had federation set up at some point, but the server is not reachable anymore. It should not cause non of your files to show up (and I guess the server wasn’t reachable even when you were still on 27).
Can you check if there’s anything else unrelated to timeouts? If yes, please post the complete message.

Edit: Although the first link above seem to be working fine for me

The file nextcloud.log in not very readable, so I took the above messages from the nextcloud web interface. But it seems they are not the same. I cannot see timeouts. Here the end:

EDIT: I think it is still related to federation or another share.

I just left the federation from the “Recent” tab, and the same for another share from another user (on the same server this time).
I have also disabled the federation app, just to be sure.

I still get, in my logs, when I go on my Files tab:
|Avertissement|no app in context|ConnectException cURL error 52: Empty reply from server (see libcurl - Error Codes) for https://wyqu84.a4.swdrive.fr/ocm-provider/

EDIT: it seems to be unrelated to my issue, but still to federations shares…

It is strange: I have just deleted à folder with files (directly on the file system), then:

sudo -u www-data php /var/www/nextcloud/occ files:scan --unscanned --all
Starting scan for user 1 out of 4 (-)
Starting scan for user 2 out of 4 (-)
Starting scan for user 3 out of 4 (-)
Starting scan for user 4 out of 4 (-)
±--------±------±----±--------±--------±-------±-------------+
| Folders | Files | New | Updated | Removed | Errors | Elapsed time |
±--------±------±----±--------±--------±-------±-------------+
| 0 | 0 | 0 | 0 | 0 | 0 | 00:00:00 |
±--------±------±----±--------±--------±-------±-------------+

It looks like a scan is not able to notice the that the file system has changed…

I think you’re chasing the wrong symptom; I believe you’re only seeing this behavior from the scan because you’re using --unscanned which AFAIK only operates on files already known to the filecache that simply haven’t been fully processed yet by the background job.

10

When you place your cursor over the + New button spot in the upper left, does a pop-up message appear saying something like “Permission denied” or similar (I don’t recall the exact language)?

11

Thank you for the --unscanned explanation.

When I place the cursor over the “+ New” button, the button is greyed out/unusable and I get the pop-up “You don’t have permission to upload or create files here”. This happens on the “All files” tab.
If I go to Favorites/My_folder, I can successfully create a new folder or text file.

EDIT:

  • I have tried a files:scan --all after adding a Test folder on the filesystem. There is still nothing on the “All files” tab, but the Test folder appears in the “Recent” tab.

  • since I performed a find user/ -type d -exec chmod 750 {} \; and find user/ -type f -exec chmod 640 {} \; on my user directory, I was not worried about permissions. All directories are drwxr-s— and I don’t know where the SGID comes from (but I guess it is okay?).

12

Shouldn´t you updated from the lastest point release V27.1.9 to major release v28.0.0?

13

I used the internal upgrade system to upgrade from 27.1.9 to 28.0.5.

It looks like a bug: if I go to Settings/share, then “select a file or folder to transfer”, I can see all my files. If I go to the Files tab, I see nothing.

Or, maybe, NC is not able to display my federation share in the Files tab, and decides to show nothing at all (?).

14

Here is the solution: no files were showing on the Files tab, because NC was trying - unsuccesfully - to connect to a federation share.

Leaving the federation share with the NC menu did nothing, and deactivate the federation app did not help. So I had to use PHPMyAdmin to suppress it manually (My_DB/ oc_share_external → suppress the faulty share).

Next time I clicked on the Files tab, I saw all my files.

Thank you!!
