I have a dedicated server that I cannot access anymore, for some reason, after a reboot. It refuses SSH connections. The machine had otherwise been running for a month without issues, and multiple reboots occurred meanwhile.
What I can do is restart it in rescue mode and SSH into it this way, at which point I can mount the hard drives (currently in SW RAID 1).
I would like to reinstall Ubuntu (14.04 as it is now, or possibly 16.04, no difference), while in rescue mode, and keeping the home folder intact. There is a lot of data in the home folder, making it a little difficult to backup. Losing this data would not be a big deal, but not losing it would be preferrable.
I have found this guide for installation over SSH: https://help.ubuntu.com/community/Installation/OverSSH but it is unclear to me how to keep the home folder and avoid deleting it.
Ideally, I would like to have the same partition scheme as now, with all partitions except 'home' formatted. I seem to have found only guides to either install via SSH, or to install keeping home partition intact, but not both.
Any help is appreciated.
