The following packages have unmet dependencies:", " libbsd0-dbgsym : Depends: libbsd0 (= 0.8.7-1) but 0.8.7-1ubuntu0.1 is to be installed

Asked by Robin Weyer

It seems the debug-Symbols for 0.8.7-1ubuntu0.1 are missing on

For Bionic the following package was build: libbsd0-dbgsym_0.8.7-1ubuntu0.1_amd64.ddeb

But on I can only find arm and other architectures for version 0.8.7-1ubuntu0.1.
The file for amd64 is missing!

What happend to this file?
I'm pretty sure I installed it last year using ansible on multiple machines.

There are other libraries like libzstd1 where the same problem is present:
libzstd1-dbgsym : Depends: libzstd1 (= 1.3.3+dfsg-2ubuntu1) but 1.3.3+dfsg-2ubuntu1.2 is to be installed"]}

For diagnostic purposes please provide the output that you receive for the following commands:

uname -a
lsb_release -crid
sudo apt update
apt policy libbsd0-dbgsym libbsd0 libzstd1-dbgsym libzstd1

And yes, it seems that libbsd0-dbgsym_0.8.7-1ubuntu0.1_amd64.ddeb is really missing on the ddebs server.
I assume it can be manually downloaded from (linked from )

Similar for libzstd; link available on
click on the triangle besides 1.3.3+dfsg-2ubuntu1.2 below "bionic" to unfold the paragraph ans to see the links

I have downloaded and installed libbsd0-dbgsym_0.8.2-1ubuntu0.1_amd64.ddeb manually before grabbing the output below.
But this can not be the desired solution for all the libraries on all the systems I need to maintain.

Of course a manual installation cannot be the desired solution.

Your output confirms the problem.
Also does not list the 1.3.3+dfsg-2ubuntu1.2 version for amd64.

I guess the best step forward is creating a bug report.
I assume that the best target is "launchpad itself"

Eventually you can start with a question in that area first
