I don’t remember the name of the formatting, but it makes it hard to
take source code and compile it.


That doesn't make a lot of sense.  LVM/no LVM and ext4 or XFS or ZFS 
shouldn't make any difference to the compiler.


I could see problems happening if they set SELinux to "enforcing" and 
put together a fine-grained and bloody-minded set of policies.  In that 
case, a compiler-generated executable might not have the right security 
context to read its config file or its data files.  Heck, "make install" 
would probably fail on a system like that even if you ran it as root and 
left PREFIX as /usr/local .

Ok, I have it now. It’s a “under a meritocratic 
 governance model. 
Debian and Ubuntu packages are not necessarily binary compatible 
 with each other, however, 
so packages may need to be rebuilt from source 
 to be used in Ubuntu.

I don’t remember the name of the formatting, but it makes it hard to take 
source code and compile it.
But I ended up chucking Ubuntu for Debian and fedora.

I found out that problem myself. Ubuntu uses a different disc formatting than 
the other distro’s uses.

Interesting.  I’ve done cloning for years with little problem.  But then, I 
don’t do RAID, LVM, or encryption.  I can see how that would be a little 
difficult.

Beware, though, of just bringing your entire home dir across to a new version.  
Often the dot files will be wrong, some fatally so. (Voice of experience!)

Agree here, cloning disks on linux haven't worked for me in 20 years, 
particularly doing anything like raid, encryption, or lvm.  Start over and just 
get a base os working.

OS is fairly irrelevant outside of sysctl's and services loading from etc, but 
meshing between major revisions or distributions here is problematic at best.  
Clean build is best.

To follow up here a clean install is my suggestion as well. Backup and
restore of your user profiles is pretty straightforward also.

Re: How to migrate Ubuntu to new computer?

[Stephen Partington]

So short answer. If the hardware is similar enough to use the same drivers
you can pull the drive and put it in the new machine. Complexity can go up
from there.

OS is fairly irrelevant outside of sysctl's and services loading from etc,
but meshing between major revisions or distributions here is problematic at
best.  Clean build is best.

I've imported my homedir's lock stock and barrel across versions and
distributions, to some varying success over the years, but I always run
into weirdness that leads me to largely blow out my home directory in doing
so too.  If I nuke my system to go to another, I largely manually rebuild
it each time.  I also try to re-document anything new, as invariably I'm
doing something with new hardware, mobo, secure-boot, and just general
distro weirdness, so it's often worthwhile to do so for next time, or at
least some good start to remembering what I did to make something work.

Again, clean is best.  Chrome has profile imports, most messaging means
too, rest I'm not adverse to rebuilding from logins to things I need.  I
get weird issues across even google profile imports, but it's much harder
to nuke that and start over, sadly enough.

Ubuntu hasn't upgraded cleanly for me between any revision since 10.04, so
I just presume I'm rebuilding it during an upgrade one way or another, and
often end up doing some major mods due to ubuntu blowing up an upgrade
horribly.  I tend to now look at it as an opportunity for improvement
procedurally, but manual rebuilds afford me some "do-overs" I do not
discourage...

Why I run Arch now with rolling upgrades - I've not had to "start over" in
years now, even with major kernel, graphics, and DE changes.  Ubuntu on my
XPS has been a general disaster since upgrading from 16.04 on it which
worked mostly, then going 18.04, even upgrading to 18.10 it's still a
basketcase.  Wayland replacement seems mostly the root cause.  Feels like
when they shat Unity upon the public randomly.

My goal is to get arch working on the xps too.  So far, I haven't had such
luck sadly, so still stuck with ubuntu for it at least for now.

first thing I would try is to clone the disks and stick them in the new

it would help if you could give the specs of the old and new computers what

A little context is needed. What are you migrating from?

If you are migrating from another Linux-based system, make sure you
perform a backup of your /home folder, plus any other folders you think
you will need to backup. Make a list of notable applications you will
need. Install Ubuntu on your new machine, and restore your backup.

If you are migrating from Windows, it is a lot trickier, and not as
straight forward.
