(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages)
If I make
dnf install polymake --allowerasing
it offers me to erase packages (Removing dependent packages) that I do not want to erase (like my own perl packages)
and also to downgrade packages like:
vim-X11, vim-common, vim-enhanced, perl!!
It is probably an issue with the updates-testing!!

Portable Fedora that doesn't suck
by Richard Shaw
For a couple of years now I've been trying on and off to come up with a
method of running Fedora in a portable manner than is easy to keep up with,
update, has decent performance, and doesn't suck :)
A pure live USB method isn't easily updatable so doesn't meet the criteria
A live USB with persistent overlay is updatable but isn't very intelligent
since it just burns up space with deltas. This method MIGHT be acceptable
if there was an easy way to merge those deltas into the compressed live
image.
A real install sucks because even with my 32GB class 10 flash memory hooked
up by a USBC/3.0 adapter the performance is terrible and updating pretty
much took 6+ hours.
All of that means the wiki[1] is pretty much useless and it doesn't look
like it's been updated for the fact that LiveUSB creator is depreciated in
favor of Fedora Media Writer.
I've looked at unionFS but depending on your tech level that may not be
considered EASY to implement and I would still like a way to easily merge
changes into the compressed image because I/O is causing the performance
issues, not CPU horsepower (Intel i5-6300U).
Anybody have some success stories they can share? Ideas? Apps or scripts
that could help automate the management of the install?
I know next to nothing about ansible, but could it be used to manage it as
a virtual host? (Not in the VM sense, but as a system on a file sense)
If I come up with something that meets the criteria I may be willing to
document it in the Fedora wiki for other :)
Thanks,
Richard

Is it possible to start without nouveau?
by Ambrogio
Hi all,
as trying to solve my problems with Unusable Fedora 26 I would be know
if there is a possibility to start with X without using nouveau.
I remember (but maybe I'm wrong) that if there is no nouveau available,
X can use the intel card but without feature from NVIDIA GPU.
If there is a way, can you explain me how to not compromise my working
installation, but how to try starting with new kernels.
This can be a good point from which to start throubleshooting problem
and try some other fix.
Tnx

Re: chronyc keeps on running

chronyc is used by a NetworkManager dispatcher script to switch NTP
sources online or offline when the network configuration is changed.
Maybe there is a bug in the script.
What chrony package do you have installed?
What does "chronyc -n sources" print?
Are you connected to multiple networks? Maybe some don't have a
default route?

F26: Print from gnome is not respect cups directive 'ErrorPolicy
retry-job'
by Dario Lesca
Into cups printer configuration file, I have set "ErrorPolicy retry-
job". When I print to a printer power off, I do not want stop printer,
I want cups still try to print until printer is power on.
And this work great if I print on a Fedora server (without GUI).
If I print a document from gnome on a printer unplugged or power off,
this printer is stopped, and when I power on it, I must go to into
control panel to start it.
How to disable this Gnome "unconfigurable" behavior (into Gnome contro
panel there are no options to do this)?
Many Thanks

chronyc keeps on running
by Ranjan Maitra
Over the past few weeks, my laptop has been running chronyc at full blast.
$top
12657 root 20 0 20624 1308 1160 R 93.8 0.0 1739:52 chronyc
I looked up chronyc and found that this controls NTP. I use NTP, but do I need to keep this around? Or is the good old ntp good enough? From what I understand, openntp would also work but that is not available on Fedora.
I guess I am wondering if there is a major cost to sudo dnf erase chronyc -y.
Thanks,
Ranjan

It isn't a problem at all since it is a failure of the drpm. Had the OP posted the
rest of the transaction you'd see that it continued on and downloaded the whole rpm.

Enable SSLv3 in Postfix
by Nelson Crosby
Hi all.
Because Legacy Software, I need to be able to support SSLv3 on my
Postfix server. From what I can figure, however, this is disabled
in the SSL library itself, as I still cannot get a successful
handshake with the following configuration line, which seems to me
like it should be enough to enable it:
smtpd_tls_mandatory_protocols = !SSLv2
If anyone has any clues, I'd be very appreciative of any help.
