Problem during the synapse update

The problem is yunohost can only restore real backup and not backup generate with an update script. I think I have to do manually.

Normally you should be able to see the backup by yunohost backup list.

Got it. But I have some troubles :confused:

Obvisoulsy, I run the command as root.

Ok,

What is your Yunohost version ?

And can you run your restore script with the --debug option ?

I have the latest version of yunohost :

yunohost --version
yunohost: 
  repo: stable
  version: 3.3.3
yunohost-admin: 
  repo: stable
  version: 3.3.1
moulinette: 
  repo: stable
  version: 3.3.1
ssowat: 
  repo: stable
  version: 3.3.2

And this is the restore with --debug enable :
https://paste.yunohost.org/raw/gotuyonepa

Definitely sounds like it’s related to :

Strange that /var/lib/matrix-synapse was not restored.

Do you have the log of the backup ?

This is the log of the upgrade which failed :

Oups. Refer to the first WARNING, it seem the file was not saved

I am not opening a new thread since I faced problems on the newest ‘upgrade’ of Synapse.

Unfortunately it failed and also removed completely my app, which makes me furious!! :triumph:

I mean I dont get it why the app has to be removed completely if the upgrade fails. Not only that, but I cannot restore the back up copy. This is the second time an app is removed, last week it was Jellyfin…I mean what is going on??

Here’s the link to the log:

https://paste.yunohost.org/raw/unusijaraj

I don’t know how to fix the situation, but the app shouldn’t be removed. Yet, it can happen because: the upgrade fails, which means the app is in a partially-upgraded-state and probably just won’t work. Therefore Yunohost tries to restore the pre-upgrade backup. And sometimes, depending on how the app works, the restore may fail too because computers are complicated and software design practices are bad for many complex reasons. Therefore Yunohost has no choice except removing the app (otherwise it would just leave a partially-upgraded or partially-restored app, which would just be broken and you’d have to fix yourself)

I understand the logic behind app removal, I find it unacceptable though to even reach to that point without any fail safe in place (testings etc) prior to release for upgrade to the users.
So any help on what should I do now? How can i restore my app to previous state? Do i install the new version and restore the back up? My media folders are intact since the app does not remove them, but everything else is gone?

Also, addition to this, I am getting many redirects requests to the domain i used to have the synapse server? Is this because the clients (Element for Android eg) are pinging the domain?

@Josue

Dear all,

I got the same error, and the same problem (synapse is gone), it may make sense to remove the availibility of the update as it may avoid the replication to many users.
I have a full backup of my server not too old that i transfered to an external drive, I guess without other solutions I will move it back to the right place and hope the backup does the job. Is there a way to backup my other app and fuse it to my full bakup to avoid loosing things ?

Note: I also updated yunohost system packages first and then synapse.

Note2: I also cannot restore the app from pre-upgrade backup.

Thanks for your help,

Best,

I encountered the same problem with synapse. Keeping a close eye on the topic )

I should have read the forum BEFORE starting the upgrade :cry:
Upgrade working for 50min now, with a load of 28 on the server, I’m quite afraid :scream:

And as feared : upgrade failed, restoration failed, impossible to restore a backup manually

The same problem, the app was removed and can’t be restored from backup

In addition to above, I tried restoring the whole backup (just the app backup failed) but it failed too… and then tried reinstall the app and failed again.

Any idea what to do ?

Aleks hi. Is there at least a way to migrate users from a backup to a newly installed synapse?

I just tested this fix to be able to restore the backup :

It is long, take your time, but it works :smiley:

Synapse is up and running !

Thank you !
I followed your way and my synapse is back :smiley:
And it wasn’t long for me.

I also learned today that if I create a “snapshot” before updating my server I could avoid these problems in the future in a few command lines or clicks and this only for a few cents per month…

I’ll keep an eye on that thread for working updates of synapses !

Best,

OK I did it to but also followed this Use Rust from package manager instead of rustup · Issue #244 · YunoHost-Apps/synapse_ynh · GitHub

since I had to install this package for my server to be restored.

Hello,

I’m using Yunohost v. 4.2.4 instaled on VPS hosted in Hetzner.
I have synapse (1.23.1~ynh1) and element (1.7.25~ynh1) installed on matrix.mydomain.net and chat.mydomain.net.
Since a few weeks i no longer can update synapse, and received these errors which I do not understand.

I will gladly take any help,

Thanks,
