Colin was so kind to also find this reference [1] in Debian. Which asks about the same revert, but not yet for it affecting VMWare - instead it seems it also conflicts with "iptables -m tos" as well.
I'll bring it up with VMWare, but if also conflicting with some iptables options that would be one more reason to revert it for 19.04, but none of us has looked deeper into it yet.

Until resolved by VMWare the workarounds for now are: Configure your client to use the old defaults permanently in => /etc/ssh/ssh_config Host * IPQoS lowdelay throughput # You might want to limit to your VMware based systems Or per command via: $ ssh IPQoS="latency throughput" user@host Two values as one is for interactive and one for non-interactive use cases. ---- original report ---- Upgrade to Xubuntu 19.04 beta from 18.10 openssh-client when trying to ssh into another system, following error: packet_write_wait: Connection to x.x.x.x port 22: Broken pipe Problem is consistent on trying to connect to various systems.
