Hi,

It looks like the compression inside the debs has changed. It seems like something Ubuntu is doing, but Debian hasn’t quite started yet. [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892664](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892664)

mbucher1@unicron:~$ ar t bsdutils\_2.36.1-7ubuntu2\_amd64.deb  
debian-binary  
control.tar.xz  
data.tar.xz  
mbucher1@unicron:~$ ar t bsdutils\_2.36.1-8ubuntu1\_amd64.deb  
debian-binary  
control.tar.zst  
data.tar.zst

We have the following ticket to track our support for zstd [[NEXUS-28889] Some Debian Packages fail to upload (control.tar.zst) - Sonatype JIRA](https://issues.sonatype.org/browse/NEXUS-28889)
