After updating Firefox I got a message to "refresh" it--that is, remove
all add-ins. Foolishly I did so, thinking to reinstall them later using
But I have not been able to get Video Download Helper to work.
I followed their instructions to install a "companion application." That
means working in a terminal version (actually, Konsole; I'm working in
KDE). The messages I get all say the companion app is ready for use. But
after repeated shutdowns and restarts, VDH still will not download anything.
On trying to fire up a VM using virt-manager, I get "unable to map backing
store for guest RAM: Permission denied".
I use hugepages to lock down memory for the VM, which may be relevant for
the error. This worked correctly on F26 just before the upgrade to F27. I
have changed nothing in my VM configuration, nor in the config file for
QEMU. However, temporarily turning off SElinux allows the startup to
proceed, after which I can re-enable SElinux with no ill effects, i.e. the
VM runs correctly.
A complete relabel of my system (touch /.autolabel and reboot) has made no
The OpenSSH 7.6p1 was submitted for testing in Fedora 27 .
Unfortunately I didn't manage to get it out before freeze since all the
thing/bugs/upstream release somehow pilled up. On the other side, this
package was already tested quite extensively during recent months by
myself, using automated test cases and was in rawhide for last two
weeks, where we caught last issues.
If you have some "special" use case, please make sure it works for you
after the update and leave a karma.

A few days ago any time I try to view a web page that contains some Flash,
Firefox (56.0) hangs for about a minute, then does something, and hangs
again for a minute, etc. Until I kill the tab for that web page.
Chrome works fine. Firefox used to work too, but now it doesn't.
Has anyone seen this?
PS. I had originally followed the instructions here to install Flash:
Yesterday Thunderbird began asking for email passwords that it should
have been finding in its password file. Edit > Preferences >Security >
Passwords is empty, there should be two passwords there.
I don't know if this is something that has happened to Thunderbirdor
I have not seen others complaining so it must be a problem peculiar to
my updated system.
I would like to start a second profile but have not been able to figure
how that is done,Google seems to provide only information on profiles
for Windows systems.
I know I have a default profile, would like to add another to see if it
will create a passwords file that willsave passwords.
Any suggestions/help appreciated.

Anybody sees this too?
Fedora release 27 (Twenty Seven)

I usually have trouble upgrading because I keep a local repository of
packages and because they are shared via NFS dnf treats them as local files
and doesn't download them. I've worked around that (F25->F26) by disabling
it temporarily and distro-syncing after update.
I've also disabled my squid package cache proxy just in case but still the
problem remains. I haven't seen anything on the list and most of the google
search results are not for F26 to F27 upgrades so does anyone have a clue
what's going on?
Now that Mozilla has provided us with its latest and greatest (sic!) Firefox, I need to prevent updates to firefox. Dnf does not appear to provide a "don't update this" option. Any suggestions?
The package mozilla-adblockplus is now disabled in all supported versions of Fedora, which have FF57 in stable. I filed https://bugzilla.redhat.com/show_bug.cgi?id=1513731 but no response yet. I can't find any sign of recent activity by the assignee, Andreas Thienemann. The last few builds of mozilla-adblockplus were by rathann (FAS name, don't know full name) who just posted builds for the new mozilla-noscript-10.1.1 (very quickly BTW, was just posted upstream a little while ago). Does anyone know if Mr. Thienemann is still active?
I have been poking at this for some hours, and by now I could use
a second opinion. Or clue. Thirteen black candles?
Somehow, when I sit on a F27 machine and pull from a F26 machine using
rsync, something extremely inefficient happens in the F26 machine.
If I sit on a F26 machine and pull from the F26 machine, it is fast.
The good state:
I had 3 reasonable machines, all on F26:
Server - 1.8Ghz Haswell-celeron dualcore
Desktop - 3.2GHz Haswell
Backup - 2.4GHz Core2Q
Backup runs rsync, and pulls from Server and Desktop using ssh.
Nothing fancy, it copies and shuts itself down.
When Backup was reading from Server, Server would have about
- 30% cpu to rsync
- 60% cpu to ssh
and deliver 100MB/s reliably. So does Desktop.
The bad state:
After one such rsync run, I upgraded Backup to F27.
When Backup pulls from Server, Server shows:
- 99% cpu to rsync
- 6% cpu to ssh
and it delivers **11MB/s**, one tenth of what it did before.
So, 30x higher cpu load per byte delivered.
So, somehow, the rsync running on F27, which by the way reports
the same version and capabilities as the one on F26, triggers
something in the spawned process that behaves differently.
On the server, the ssh-spawned rsync process looks the same whether
it is Backup or Desktop pulling from it:
On Server, with Backup as client, 11MB/s:
root 25042 34.4 0.0 124996 5620 ? Rs 18:54 0:40 rsync
--server --sender -vlogDtpre.iLsfxC .
On server, with Desktop as client, 100MB/s:
root 25152 31.9 0.0 122344 3000 ? Rs 18:56 0:05 rsync
--server --sender -vlogDtpre.iLsfxC .
The command being run on Backup or Desktop is:
rsync -av -e 'ssh -i id_ecdsa' --exclude XA/ --exclude video2/
email@example.com:/bulk/mux/media/xbn* . --progress
Things I did:
Tried the still-installed F26 and F25 kernels
Desktop (F26) can rsync to and from Server(F26) at full speed.
All machines get 110MB/s when running iperf, all six ways.
The Sky2 nic in Backup is not spewing errors
iperf shows no dropped.
Swapped switchports between Desktop and Backup
Switch does not report errors
Things to do:
upgrade a sacrificial F26 machine to F27 and try from that
