Resolved Backup problem after upgrade to Obsidian 18.0.40

[Kulturmensch]

Since the upgrade to Obsidian 18.0.40 my daily backups do not work without error messages. Does anyone know what these messages mean and how to solve the problem?

The errors are:

Warning: Subscription "tenckhoff.de"

I am facing the exact same issue after upgrading to 18.0.40. Unable to find an answer online. Already tried to resolve it with plesk repair, but it did not help.

I have the same issue. Seems to be only happening on Ubuntu 20.04.03 LTS. The issue didn't occur on other instances (e.g. Ubuntu 18.04.6 LTS).

Tried installing:

sudo apt-get install -y libboost-filesystem-dev

But this didn't help.

It is known bug PPPM-13321.
Developers are working on it.

Great that it's already fixed (post by @IgorG above) but FWIW we have no incidences at all of this error and all our servers are on Ubuntu 20.04.03 LTS

Please fix this quickly! Not being able to make backups is serious.

I have the same problem since the 18.0.40 update.
hostnamectl status
Virtualization: openvz
Operating System: Ubuntu 20.04.3 LTS
Kernel: Linux 5.4.0
Architecture: x86-64

Is there any workaround available to backup at the moment? Daily snapshots of the whole instance aren't really practicable...
Is there any way where I can see the current status of the known bug ticket PPPM-13321?

Can you give us an update? Backups of my critical websites are well overdue.

Please be patient. The hotfix will be released soon.

I just tried the backup since the new update 1 and ... it works again. Thank you for the quick solution. For me the issue is resolved.
