Actually, "it didn't re-download any of the cached packages" would be
the correct wording here.

You're right.  I've just tested it without copying the file (just the
dir with the packages) and running "dnf system-upgrade download"
worked as expected -- it didn't download anything and just created the
file, making it possible to run "dnf system-upgrade reboot"
afterwards.  This is definitely the correct approach, thanks.

Actually, this is correct -- system-upgrade puts them in
/var/lib/dnf/system-upgrade, not in /var/cache/dnf.  Copying this
folder alone isn't enough, though.  One must also copy the
/var/lib/dnf/system-upgrade.json file.


Have you tested that it is necessary?  Personally, I would not want to 
copy that file and just let system-upgrade create it on each computer. 
DNF should still use the copied files if they are relevant.

Actually, this is correct -- system-upgrade puts them in
/var/lib/dnf/system-upgrade, not in /var/cache/dnf.  Copying this

/var/lib/dnf/system-upgrade.json file.

IIRC in this folder are the packages already resolved. I would do system upgrade
properly. If you still think loosing your data worth saving 3.2Gb of transfer 
then
try rather this:

I did say he should run "dnf system-upgrade download" on each computer 
to make sure the package set is consistent for each one.  But that is 
the directory to copy to save the downloading.



dnf system-upgrade download --releasever=23 --refresh --setopt=keepcache=1
# copy /var/cache/dnf/fedora* to other machines
dnf system-upgrade download --releasever=23  # on other machines
dnf system-upgrade reboot  # everywhere

I don't have a computer to test with right now, but I'm pretty sure 
system-upgrade doesn't put the packages in there.  So at most you will 
be merely copying the repo data across.

Those directories don't even exist.

The one you want is:
/var/lib/dnf/system-upgrade

Once you run the download on the first one, copy that directory to the 
next computer.  But still run the dnf download command on every computer 
to make sure you have the right packages.  If the package already exists 
in that directory it won't download it again.

22-> 23 on multiple hosts

[Frank Elsner]

Hello,

I've to update 3 laptops from Ferdora 22 to fedora 23.
"dnf system-upgrade download --releasever=23" wants to download 1.6 GB.
I don't want to do this 3 times and came to the following idea:

Host 1Host 2
dnf system-upgrade download --releasever=23
/var/cache/dnf/i386/23 -> /var/cache/dnf/i386/23
  
/var/cache/yum/i386/23 -> /var/cache/yum/i386/23
dnf system-upgrade reboot dnf system-upgrade reboot

Will this work?
