[Bug 1693160] Re: software notifies a problempackage openssh-server 1:7.2p2-4ubuntu2.1 [modified: usr/sbin/sshd] failed to install/upgrade: unable to make backup link of './usr/sbin/sshd' before installing new version: Operation not permitted

Hello Dorothy,

Please ask whoever takes a look at your computer to inspect this bug.
("ubuntu bug 1693160" should suffice.) These error messages are unusual
and may indicate that ssh and sshd have been set immutable, or set to
mode 0000, or something even more surprising.

If you never use ssh to connect to other computers, or allow others to
connect to your computer with ssh, perhaps these should be removed
entirely.

Thanks
