Correcting my off-list post by cc-ing back to the list ... once again,
I've got a file.. with a bunch of lines looking like:
$bookVariable['wmich']['Summer II 2017']='1';
$bookVariable['wmich']['Summer I 2017']='1';
I''m looking to get the "text" inside the 1st group of brackets 
The following sed only gets the 1st 3 lines.. and it doesn't completely work.
sed -n "s/^.*bookVariable\['\(\S*\)'].*$/\1/p" foo.txt

cannot play mkv files :(
The video player I select in preferences is mplayer.
Even if I change it to mpv, it will not play mkv.
However, if I invoke either mplayer or mpv from command line, then
they do play the .mkv file.
Some years ago I had an IBM ThinkPad that one day failed to boot, and every
subsystem diagnostic that ran at power-up (keyboard, memory, disk
controller, ...) reported a problem. On a whim I put in a new clock
battery and everything was fine. Now any time a machine suddenly goes
flakey, the clock battery is the first thing that gets replaced.

I need OpenVPN 2.3 because the end router has an outdated OpenVPN
version and OpenVPN 2.4 broke compatibility.
2 weeks ago I accidentally updated to 2.4 but I managed to do dnf downgrade.
However, after I updated Fedora 25 today I can no longer downgrade, it
says it is at lowest version.
OpenVPN upgraded even tho I explicitely set
What is the correct way to avoid this in the future? How to properly
prevent package from updating?
Luckily I found 2.3 rpm on rpmfind so the day is saved for now.
This is an f24 system. I just (about 1pm US mountain time) completed my
weekly "dnf upgrade", and I saw no hint of failure or trouble. But when
I shut down the system, and then powered back up, the boot failed. The
grub menu looked ok. The blue-and-white bar at the bottom of the boot
screen did go most of the way normally. But it never got to the log in
screen. There was some text being displayed, but I have no way of
capturing it, and I don't remember what it said.
I'm no sys. admin. I have no idea what to do. Please help. (I'm using
a windows 7 system for this e-mail.)
Thank-you in advance.
Within the last couple of days an update is causing LibreOffice to
crash. When I click on the icon, recovery mode comes up, but there is no
file to recover, and when I click "OK" the Logo comes up briefly and
then goes away. When I try to run from the command line, I get
I have tried reinstalling but get the same "Application error" when I
attempt to run it from the command line.

I have a computer running fc25.x86_64. It has one folder, /home/photo,
with ~100 GB of photographs (about 40K files) organized in many
subfolders named like username/year/YYYYMMDD-event
I use rsync to have a full copy of that folder on an external drive,
connected via USB. This morning, rsync copied many new files without
problems, but at a certain point it failed. It left behind on the drive
a folder which "looks" empty, but it isn't, and cannot be removed.
Commands and error messages are below.
The questions are
- may this be a software-only problem? Maybe caused by "system
overload"? I also had a text-analysis script running, using all the RAM
and CPU it could get. Also, probably irrelevant: at some point one of
the kids plugged a smartphone into another USB port, to recharge it :
- assuming the fault is not in the drive... how should I get rid of that
corrupted folder? I already tried unmounting and remounting, but no
rsync -rvt --delete --no-o --no-g /home/photo/ /run/media/marco/TOSHIBA\

after that folder...)

Unable to make wodim record at 2X, even with driveropts=forcespeed:
wodim -v dev=/dev/dvd speed=2 deriveropts=focespeed,audiomaster -audio
but it continues ... and reports it is recording at 8.5x.
Any info on this?
