I don't have physical access to the server at the moment and I want to upgrade to 18.04 clean fresh (if possible) from the existing install I'm running now.



As no physical access is possible I'm thinking that a couple of things need to stay:



  • sshd running

  • networking so I can connect

  • user/password


  • /home if possible

By clean install I mean that I want to go as close to a new 18.04 install as possible and I'll rebuild my system myself.



Any ideas?

    Is it really wise upgrading a server to a new release without having physical access ? (Forget the theoretical, I just would not embark on this lightly). My genuine advise is "don't". That said, there is the command "do-release-upgrade". Please,please,please make sure you backup all your config and all your data before you upgrade. Please consider arranging physical access and installing from fresh (on a second HDD if possible, in order to preserve the first in case of disaster) if you absolutely must upgrade to 18.04.

  • if everything breaks I can get physical access but the local helper is hard to work with... Second I have full rsync of the box and all the important things are in dockers.

  • To reviewers: I don't see how this problem is specific to 18.04, the answer certainly isn't.

Sometimes the answer to a question is:



Please, don't do this!



Because you might have a full rsync backup, but it's not about the backup: It's about the restore! How long is the restore going to take? How are you going to restore if you don't have access?



Unless you have all of the following:



  1. Remote console access!

  2. A full bootable off-line back-up (E.g. CloneZilla even if it's on a 128GB USB Stick or a 1-2-4TB USB HDD)

  3. The off-line backup drive contains a small 64 GB bootable partition containing a customized CloneZilla environment that will let you ssh into it to be able to do the restore.

  4. 18.04.1 (never install the first version of an OS, that is true under any OS whether it's DOS, NetWare, Windows, *nix, BSD, ...)

If all of the above is true, just do a do-release-upgrade



¯_(ツ)_/¯

How to enroll fingerprints to Ubuntu 17.10 with VFS491

Image
Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
