Can't access via browser, corrupted sd card

beaujean98 · 27 May 2024 17:50

Since a few days, I can’t access the nextcloud app nor syncloud platform from any of my devices, be it in the local network or not. I have restarted the machine a few times. I can log on via ssh. This is pretty annoying, any help is greatly appreciated. I saw these commands on other threads, so I"m pasting the output below. Here is what firefox says


Unable to connect

An error occurred during a connection to 192.168.178.70.

Hi,

Could you send logs from Settings please?
What browser says for nextcloud ?

beaujean98 · 30 May 2024 13:13

I can’t access the syncloud web ui, so if you mean the settings from the browser, I can’t access them. I only have ssh access. Same issue for accessing nextcloud.myname.syncloud.it or 192.168.X.X in the local network, the browser says: Unable to connect

The nextcloud client on my laptop says: No connection to Nextcloud at https://nextcloud.myname.syncloud.it. Connection refused

So I think it’s not a DNS or routing problem, it worked fine for months before and I didn’t change the network configuration.

So which logs should I provide? Please tell me the command to run in the terminal

I see that /var/syslog is full of these entries:

ok, can you run these on device:

systemctl status snap.platform.nginx-public
systemctl status snap.platform.backend
curl -v https://localhost

Here are the failures. How to fix them?

what about this:

snap restart platform
systemctl status snap.platform.nginx-public
systemctl status snap.platform.backend

beaujean98 · 30 May 2024 14:50

This doesn’t help, unfortunately. Any other idea?

root@syncloud:~# snap restart platform

Looks like a disk/sd card error.

SQUASHFS error: Unable to read fragment cache entry [60]

What kind of device is this?

boris · 31 May 2024 07:48

Hopefully you are using extremal disk for storage.
You need a new sd card and follow this instruction to do a factory reset: Home · syncloud/platform Wiki · GitHub

External disk can be activated again.
Also apps can be restored from the backup if you used backup feature.

To confirm it’s the SD card, I ran

This shows I’m using an external disk, didn’t know that one was on btrfs, I know that from 20 years ago. But yeah, the snaps are on squashfs with the internal SD card. I have been doing regular backups, so I will get a new SD card and restore the system

beaujean98 · 4 June 2024 20:39

@boris thank you for your help so far

Just to make it clear for my future self in case this happens again, here is what I did:

Copy the app backups and files to an external disk
Remove the corrupted SD card
Buy a new SD card of the same size
Download the syncloud image and use an etcher to write to the new SD card
Reboot the Rasberry PI
Log in the same credentials as before
Extend SD card memory
Install Nextcloud app
Activate external disk: it says you can format it, don’t worry, it doesn’t unless you explicitly want
Open Settings-Backup and restore from the latest users and nextcloud backups
Next the server is down, I couldn’t start nextcloud app in the browser, nor ssh, so I rebooted the rasberry PI.

The users app doesn’t show the user accounts I created before, only the one account created upon initialization

I cannot log into the nextcloud app with the main account, using the credentials that work at least to log into the users app.

What went wrong here? The backup/restore functionality doesn’t work, unfortunately. Before I made productive use of this system in January, I restored from a backup with some mock data and it worked fine.

Could it be because I may run a newer version of syncloud/the apps now compared when I made the backups? When restoring, it said it was successful but I can’t confirm that. Here is what updates says about the current versions:

System: 2164
Installer: 595

The users app doesn’t show the user accounts I created before, only the one account created upon initialization

Users app does not really store users itself it just allows you to modify platform/system users, so it does not make sense to backup/restore it.

boris · 4 June 2024 20:51

I cannot log into the nextcloud app with the main account, using the credentials that work at least to log into the users app.

When did you make a nextcloud backup last time?
Can you login to device itself?
I think someone reported the same thing, am I right that you could login to nextcloud after fresh install but cannot after the backup restore?

beaujean98 · 7 June 2024 19:55

Here is the log output when I attempt to log into nextcloud and get denid

I removed and re-installed nextcloud, and also removed the users app. After the install, I can log in and see the files that are still stored on the external disk. But no other users. When I restore from the latest backup, which is from Mar 30, and reload the page, I get a 502 Bad Gateway error. The log lists this error

I really don’t want to lose the calendar data and users that should be stored in the nextcloud backups. How can I retrieve them? Also, I have multiple users, and would like to avoid re-creating their accounts so they would have to re-upload their files. Any tips? I still have the old SD card, is there perhaps a hack in the terminal to get the Nextcloud data out?

Back to the users app.
If the users app doesn’t make sense to backup, why is there a backup option? That’s misleading.

I noticed that nextcloud creates an account for everyone I added via the users app, so I thought I would first re-create the users, and then restore nextcloud so it would have all the right users. But of course you can create users separately in nextcloud, which I also did.

Agree, but we need to find a way to backup users.

Also, I have multiple users, and would like to avoid re-creating their accounts so they would have to re-upload their files. Any tips

Actually if you recreate an existing user with Users app Nextcloud will find its existing files as long as user name is exactly the same.

boris · 7 June 2024 21:20

You can check if you have existing user files:

ls -la /data/nextcloud/username/files

Where username is a user logn name.
