[Bug 1802644] Re: package openssh-server 1:7.6p1-4ubuntu0.1 failed to install/upgrade: installed openssh-server package post-installation script subprocess returned error exit status 127

Hi,
thanks for the analysis. Indeed I had installed a custom version of libreadline and it caused many troubles (even preventing Ubuntu to start).
I do not have enough knowledge so I could not link it to this bug I reported because Ubuntu proposed me to report it.
I will change the status as "Invalid". If you think that this is not correct, please change.

** Changed in: openssh (Ubuntu)
       Status: Incomplete => Invalid
