Bug while upgrading from 5 to 6

[Sloug]

Today I've tried to upgrade my proxmox from the latest 5 release to version 6.
My proxmox is not a pure proxmox installation, it was installed onto a debian system, to enable a full disk encryption.
I had done everything according to this guide: https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0
There is only 1 node and no ceph so it should be quite easy.
After I had overwritten als sources lists to the buster version and did an apt upgrade I've tried to execute apt dist-upgrade, while this was runnig I got the following error:

Unpacking libjsp-api-java (2.3.4-2) ...

This bug is already reportet in the debian bugtracker:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=947844

As you can see in the last post on Sat, 28 Mar 2020 there was written:
"I will upload new packages to stable-proposed tomorrow but it may take a
few days until they will be accepted."

So my question is, when can I expect a fix for this bug in proxmox repositories, or is there any other problem why this is not fixed?
Is there any workaround for this bug, it would be nice, because I want to finish my upgrade as soon as possible!

Thanks for your help

This is a package from Debian, not maintained by Proxmox (and not part of the Proxmox repositories).

Also, please follow the bug status in the debian bug tracker.

Thanks for your quick reply, I was not sure if this is also a proxmox-dependecy, so this was really helpful. I'd removed the libservlet3.1-java package and restarted the dist-upgrade. Nothing went wrong this time, so I'm now on pve 6, too.

Thanks!!
