Dpkg error processing package openssh server

Something seems to have gone wrong with openssh-server on my machine. I’m on Ubuntu 20.04.
I noticed this trying to install another package that depends on openssh-server.

When I tried to re-install it says it is configuring a «partially installed package» so I must have missed something happening with this package on a previous upgrade I think.

andy@andy-UX303UA:~$ sudo aptitude install openssh-server

I got the same errors after running aptitude remove openssh-server and then trying to re-install it. Any ideas what to try next?

Привет всем! Это снова я и мои проблемы
Не устанавливается ssh, хоть тресни!
Перепробовал кучу советов из гугла, но результат один:

dpkg: error processing package openssh-server (--configure):
 installed openssh-server package post-installation script subprocess returned error exit status 255
dpkg: dependency problems prevent configuration of ssh:
 ssh depends on openssh-server (>= 1:7.6p1-4); however:
  Package openssh-server is not configured yet.

dpkg: error processing package ssh (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 openssh-server
 ssh
E: Sub-process /usr/bin/dpkg returned an error code (1)

Пробовал удалять и снова ставить, удалять через purge, autoremove, autoclean, upgrade, reconfigure, -f install, чистил кэш apt.
Может быть кто-нибудь знает секрет, помогите пожалуйста

Ура! Буквально только что нашел выход.
Идём в каталог /var/lib/dpkg/info и удаляем там всё что связано с openssh-server. Установка произведена, но осталась еще одна ошибка:

OpenSSL version mismatch. Built against 100020ef, you have 1000114f

I had openssh-server working on my dedicated server running proxmox, but everytime I tried to upgrade anything I got this error:

dpkg:error processing package openssh-server (--configure):
subprocess installed post-installation script returned error exit status 10

So I read on forums that I should uninstall and purge openssh-server and install it again therefore I ran proxmox shell which doesn’t need ssh to connect to server and remove openssh-server.

Now I cannot install it and I don’t have ssh access to my server.

I tried this:

$ dpkg --configure -D 777 openssh-server
...
D000400:       checking breaker openssh-sftp-server:amd64 virtbroken <none>
D000400:     checking virtbroken openssh-server

D000002: fork/exec /var/lib/dpkg/info/openssh-server.postinst (   configure   )
dpkg: error processing package openssh-server (--configure):
 subprocess installed post-installation script returned error exit status 10
D000001: ensure_diversions: same, skipping
Errors were encountered while processing:
 openssh-server

I also tried removing openssh-server* from /var/lib/dpkg/info and installing it again I didn’t have any success.

My OS is Debian Stretch and I installed proxmox kernel on it.

How can I install openssh-server with these situation?

Previously, we published a general guide on how to fix E: Sub-process /usr/bin/dpkg returned an error code message on SSH. Here is how to fix openssh-server E: Sub-process /usr/bin/dpkg returned an error. Do not close an active SSH session with this error. These errors are not uncommon on virtual servers, cloud servers for the virtual appliances. There can be a minor bug of the virtualization software or drop off some packets during the virtual server update process. The result becomes errors in postinst files. It is not dangerous on virtual servers than it delivers the feel. Virtual servers always have some way to “enter” by the admin. It is dangerous on dedicated servers.

Any web host will happily fix this error if you loss SSH connection and ask their help. But, we give importance to running some commands to test to fix own-self (which increases the experience of server administration).

Run these commands :

You’ll see list of files something like openssh-server.md5sums, openssh-server.postinst, openssh-server.postrm. Create a sub-directory under temporary with identifiable name :

Move all those files from /var/lib/dpkg/info to that temporary directory :

Run :

The package should not return the E: Sub-process /usr/bin/dpkg related error anymore. If still disturbs, your luck is bad. The problem is likely to be with /etc/apt/sources.list. You can try to restore sources.list to default, purge the unused software packages. You may try these :

You should take help of your web host to run :

I have not seen any good result by running the other common commands peoples usually suggest. As a rule, always carefully check all the log files for any attempt to breach the security of SSH. Virtual servers are vulnerable to various exploits which we can manage with physical components on the dedicated. But virtual servers offer a big advantage – web hosts provide free help even to the unmanaged servers around SSH and networking issues.

Always keep your servers updated, regularly reboot on need, notice the errors while updating & upgrading, check what software packages are not in use (apt list --installed list the packages).
