system-upgrade

[François Patte]

Bonjour,

I have a computer which runs fedora 29, may I use dnf system-upgrade to
upgrade to fedora 32?

Thank you.

If not, what is the safer way to upgrade?

system-upgrade is expected to work across two versions, but not
necessarily across three. The official way would be to upgrade either
from F29->F31, then F31->F32, or from F29->F30, then F30->F32. However
you might be lucky with F29->F31.

I'd recommand doing one version upgrade at a time.
You are suppose to be able to upgrade 2 versions, but I once had it fail 
and system was not easily fixable, so just did a clean install that was a 
pain to get back to the state of the system.

I just updated two machines from fc31 to fc32 using dnf with no 
problem.

I generally create a list of packages installed, so If I want to do a clean 
install, and then make the new system have a similar setup instead of 
have to manually do it.

#!/usr/bin/bash
rpm --qf "%{NAME}.%{ARCH}\n" -qa | sort  | grep -v gpg-pubkey > 
installed_pkgs`date +%F`.txt

Then can pipe that into a dnf install. Sometime have to remove some 
lines for packages that no longer exist or have been replaced.

Good Luck.

I've done a lot of F30 to F32 upgrades with no problems.

Was asking about the safest way. I've also done a number of two version 
updates over the years. Had a classroom with 21 computers, and 
generally, wouldn't do an upgrade in the middle of a semester, so 2 
version upgrades where common. It was just one time years ago, that 
doing the two version upgrade caused a system to fail to boot after the 
upgrade. Tried a couple of things, but couldn't get it to work, so just 
reimaged it to the previous setup, and did two 1 version updates that 
worked fine.

Always, did an image backup before just in case, but also had other 
systems that could be reimaged to it if a problem happened.

Takes more time, and probable not likely to have any issue, but one 
never knows.

Retired after 36 years of teaching, so haven't done a 30 to 32 upgrade.
Started with Unixware as first unix related system, and the went to 
RedHat 9. Went from Fedora Core 1 to the Fedora 32. Have 5 linux 
systems at home doing stuff. 3 are Fedora 32, 2 are still Fedora 31.
