Cannot install SSH.

DigitalOcean Ubuntu 16.04

The password for one of our user names wasn't allowing us to login. We changed the password, but had the issue again.
In attempt to fix this I reset the SSH. Now ssh will not reinstall.

When trying to re-install the server we get the following errors

"Openssh-server" has no installation candidate"
"Package openssh-server is not available, but is referred to by another package. This may mean the the package is missing, has been obsolete , or is only available from another source.

E: Unable to locate package ssh
E: Package 'openssh-server" has no installation candidate

if you use ubuntu 16.04 or debian jessie OS than double check your sourcelist

step 1
Debian sourcelist sourcelist

deb jessie main non-free contrib
deb-src jessie main non-free contrib

deb jessie/updates main contrib non-free
deb-src jessie/updates main contrib non-free

ubuntu 1604 xenial sourcelist

deb xenial main restricted universe multiverse
deb xenial-updates main restricted universe multiverse
deb xenial-security main restricted universe multiverse
deb xenial-backports main restricted universe multiverse

step 2
after you can update your repo list and install openssh-server

apt-get  update
apt-get install  openssh-server

if you any problems with apt-get update than

rm -rf /var/lib/apt/lists/lock

and goto step 2 and run the commands again

Dont forget to stay over the droplet console while reinstall your ssh server.

Sorry you're having trouble. Did you first run apt-get update before attempting to install openssh-server?

  • Yes. For a long time the SSH was working well, but it stopped working after we reset it.

    Why did we feel we needed to reset it?
    For some reason unknown to us, the password for one of our important usernames stopped working. Even when we changed the password using 'root' it continued to malfunction. Despite multiple password changes we were unable to access that account.
