Downgrade from 34 to 33

How can I downgrade from 34 to 33? :slight_smile: I’m getting a conflict when executing:

sudo dnf system-upgrade download  --releasever=33 --allowerasing --skip-broken
...
Error: Transaction test error:
  file /usr/lib64/libip4tc.so.2.0.0 from install of iptables-libs-1.8.5-5.fc33.x86_64 conflicts with file from package iptables-legacy-libs-1.8.7-4.fc34.x86_64
  file /usr/lib64/libip6tc.so.2.0.0 from install of iptables-libs-1.8.5-5.fc33.x86_64 conflicts with file from package iptables-legacy-libs-1.8.7-4.fc34.x86_64

And I don’t see how I can work around it.

  • OK…it’s a safe run for you (also, add --skip-broken), remove conflict package and then run below;

    dnf system-upgrade download --releasever = 33 --allowerasing

Does not let me do that:

dnf remove iptables-legacy-libs-1.8.7-4.fc34.x86_64 --skip-broken
Error:
 Problem: The operation would result in removing the following protected packages: systemd

in this case…do not use “–skip-broken” also it can be use…cheer up!!! :boom:

rpm -e iptables-legacy-libs-1.8.7-4.fc34.x86_64
yum autoremove  iptables-legacy-libs-1.8.7-4.fc34.x86_64
dnf autoremove iptables-legacy-libs-1.8.7-4.fc34.x86_64

That also fails: :expressionless:

 sudo rpm -e iptables-legacy-libs-1.8.7-4.fc34.x86_64
error: Failed dependencies:

gracefully run…do not show any problem within my test system.

Fedora changed Firewall Backend from iptabled to nftables.

it’s a just program conflict problem for downgrade progress.

In the end, I decided to reinstall the operating system.
