I am currently experiencing the problem that my freeradius installation with the kerberos5 module does not like my rcache. It spits this error when authenticating.
ERROR: (0) krb5: Error verifying credentials (-1765328174): Generic preauthentication failure
According to Kemptechnologies this error code means the rcache format is not supported.
-1765328174
KRB5_RCACHE_BADVNO
Unsupported replay cache format version number
I tried to disable rcache by using the information provided by MIT.
http://web.mit.edu/kerberos/krb5-devel/doc/basic/rcache_def.html
Setting KRB5RCACHETYPE to none to disable it, setting it to dfl and setting the KRB5RCACHEDIR to /tmp but freeradius seems to not like any option.
Can anyone tell me how i have to format the rcache so that freeradius is able to read it?
I bought a HotPi a while ago, and decided to use it. So I followed the procedure to configure the IR and after a few hours I was able to IR signals on my Raspberry 1.
But my purpose here is to send IR signals, which I tried, without any luck.
So this is the command I try to do (just for test):
irsend SEND_START devinput KEY_POWER ; sleep 3
And this is what lircd tells me:
lircd-0.9.4c[907]: Notice: accepted new client on /var/run/lirc/lircd
lircd-0.9.4c[907]: Info: Cannot configure the rc device for /dev/lirc0
lircd-0.9.4c[907]: Error: invalid send buffer
lircd-0.9.4c[907]: Error: this remote configuration cannot be used to transmit
lircd-0.9.4c[907]: Error: error processing command: SEND_START devinput KEY_POWER
lircd-0.9.4c[907]: Error: transmission failed
lircd-0.9.4c[907]: Info: removed client
Edit:
It seems I'm not using the good drivers. According to the HotPi documentation, I'm suppose to use lirc-rpi, which I'm suppos to install with
sudo modprobe lirc-rpi
Which, at least, doesn't return an error. But trying to configure the interface tells me that the driver doesn't exist:
pi#raspberrypi:~ $ mode2 --driver lirc-rpi --device /dev/lirc0
Driver `lirc-rpi' not found. (Missing -U/--plugins option?)

Here is no info what lirc version you are using. There are vast differences between the legacy 0.9.0 still used in some distros and modern lirc.
That said, the logs seems pretty clear. You are using the devinput driver, right? This driver does not support sending data, reflecting the fact that also the kernel doesn't.
You then need to use another driver - first stop might be the default one. If/when using this other driver, you need another lircd.conf.
Please refer to http://lirc.org/html/configuration-guide.html
EDIT: Ah, lirc-0.9.4c says the log. Sorry, my bad. The reply should still be valid, though.
When you record the remote, use:
irrecord -d /dev/lirc0 -f name.conf
The -f uses raw mode. This then worked for me on the transmit side, before I got same error as you.
I recently bought a Lenovo 500-15ACZ notebook and installed Ubuntu 16.04 on it. After the installation I found I couldn't connect to Wifi. When I googled the issue, this seemed to be a common problem for Broadcom wifi cards. I found this question on askubuntu and followed the steps of the answer by Luis Alvarado.
The command lspci -nn -d 14e4: showed me that the pci.id of my device is 14e4:43ae rev 02, which is not yet supported in Linux.
However, there is a script (link to project) on git that tries to solve this via backport:
#!/bin/bash
cd /tmp
git clone https://github.com/kvalo/ath10k-firmware.git
cd ath10k-firmware/QCA9377/hw1.0
sudo mkdir -p /lib/firmware/ath10k/QCA9377/hw1.0
sudo cp board.bin /lib/firmware/ath10k/QCA9377/hw1.0
sudo cp firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin
sudo modprobe -r ath10k_pci
cd /tmp
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar -xf backports-20151120.tar.gz
cd backports-20151120
make defconfig-ath10k
make
sudo make install
But when I tried to run this, make threw the following error:

Update:
I installed the broadcom-sta-dkms package as you suggested. Unfortunately, you were right; this didn't work.
When I tried the wl driver, dmesg | grep -i wl returned [
12.459884] wl: loading out-of-tree module taints kernel.
[ 12.459890] wl: module license 'MIXED/Proprietary' taints kernel.
[ 12.468203] wl: module verification failed: signature and/or required key missing - tainting kernel
[ 12.487603] wl driver 6.30.223.271 (r587334) failed with code 1001
[ 12.487606] ERROR #wl_cfg80211_detach :
[ 12.487607] NULL ndev->ieee80211ptr, unable to deref wl
However, I'm afraid I am not sure what this means. For the other drivers, dmesg returned nothing.
Well, I'd suggest to be consistent. You have a Wi-Fi device and you know its PCI vendor ID (which stands before the colon) and device ID - 14e4:43ae. In your question you don't provide a complete excerpt from your lspci, so it's not clear whether your device is indeed identified as Broadcom. However, if we assume it's true, we can search for it.
Here is what WikiDevi page says:
802.11a/b/g/n/ac WLAN + Bluetooth 4.0 NGFF 2230 Mini Card
WI1 chip1: Broadcom BCM43162
Probable Linux driver unknown
PCI ID not yet observed in any mainline kernel / this list
So, as you might see, this page sheds light on such important things like chip naming and current observation of kernel code awareness of such PCI ID. The latter means that, according to their research, no one driver in the main kernel tree has such an ID in the corresponding PCI ID table by means of which the kernel makes a decision to probe a specific driver for a given device. Nothing known about the PCI ID.
But now we know for sure that this one is indeed a Broadcom device.
Looking at your excerpt from the script (which you are trying to make use of) baffles me a lot since it's for Qualcomm Atheros, not for Broadcom. It tries to grab QCA firmware from (possibly) untrusted repository and compile ath10k backported driver. So, at this point we know that the question merely about the compilation errors is unhelpful from the very beginning. But, of course, one may suppose that either Linux kernel headers package is not installed or the version of backported ath10k is not compatible with your current kernel. That's it.
So, it's clear that we shall look for Broadcom drivers (and, possibly, for Broadcom firmware) instead. From this perspective I can tell you that three types of drivers are available for Broadcom devices: b43 (mostly legacy), vendor-licensed broadcom-sta (wl) and in-tree brcm80211. The latter one is a common name for brcmsmac and brcmfmac.
Here are the authoritative pages with up-to-date info:
b43 - http://linuxwireless.org/en/users/Drivers/b43/
brcm80211 - https://wireless.wiki.kernel.org/en/users/drivers/brcm80211
Also, a more or less descriptive page for the vendor-licensed wl:
https://wiki.debian.org/wl
I can't find your PCI ID on either of the pages. This indeed confirms that corresponding support has not been added yet. However, we can confirm this further by just trying the drivers on hands. It's obvious that in-kernel b43 and brcm80211 don't work for you, but it might be useful to take a look at dmesg - perhaps, brcm80211 is loaded but can't find FW.
If nothing useful is found, then it would be nice to try wl. This driver is distributed by means of broadcom-sta package (Debian, Ubuntu), and I can mention the corresponding description on Ubuntu website.
So, to try wl you need to make sure that you have proper Linux headers and then just install broadcom-sta-dkms package.
apt-get update
apt-get install linux-headers-$(uname -r)
apt-get install broadcom-sta-dkms
Hopefully, it will compile and install it. Then you should do a reboot and take a look at what happens with your Wi-Fi. Most likely, this won't help (since I suppose that your device is really not supported yet), but if it works, you will be able to use it. Even if you see for sure that your device doesn't work with wl, again, like in the case of brcm80211, it's worth taking a look at dmesg output. However, in example, seeking for a valid FW image (if dmesg complains about it) is a separate question and should be discussed accordingly.
Also, I can expand on this topic and mention that in certain mailing lists on the net some folks have already asked about plans to add support for this device. Here is one of the links. So, if neither brcm80211 nor wl (broadcom-sta-dkms) help you, you may consider sending an email to one of brcm80211 supporters. Their names and email addresses are listed on the page. There are Broadcom employees among them. If you ask them for a good piece of advice, you will also help other people.
UPDATE
So, you say that b43 (also b43_legacy) and brcm80211 keep silence in dmesg. This could mean that your PCI ID is not supported by these drivers.
What's for wl output, I can share my output for comparison:
wl: loading out-of-tree module taints kernel.
wl: module license 'MIXED/Proprietary' taints kernel.
Disabling lock debugging due to kernel taint
wlan0: Broadcom BCM43a0 802.11 Hybrid Wireless Controller 6.30.223.271 (r587334)
This obviously means that your output minus this one gives some sort of silence again. However, it's too murky to say for sure whether your device is unsupported or there is some FW issue.
So, it seems like no options remain here.
However, you still may consider ndiswrapper solution. In two words, it's a special tool/driver which enables you to install a proper inf and sys files from the Windows driver (i.e. you should obtain it for your card somewhere, eg. extract from the CD or download from Broadcom webside) in such a way that the driver would operate in Linux as it was in Windows environment. This type of solution has its drawbacks and limitations. First of all, only Windows XP versions of wireless drivers are supported, so if you've got, say, a ZIP package from the vendor's website, you need to extract inf and sys files from the directory named after Windows XP (not Vista/7/10), and you need to pay attention to CPU architecture choice (32 bit / 64 bit). Here is an article from Debian which could fit Ubuntu as well. But this kind of solution overall may face some extra drawbacks and suddenly bad operation (it's a topic for a separate talk) and also in general it is considered as bad solution for missing driver. So, many people in such a situation just prefer to swap their unsupported card with some other one or just wait until the missing support is added to one of the native drivers. It's up to you.
I'm running MATLAB on since about one and a half year now. And I've been trying to get matlabpool ready to go once in nearly every three months. Before I give up on it completely, I've decided to ask for help. :)
My problem starts with matlabpool command. Whenever I type in the matlabpool command, I get this :
One or more output arguments not assigned during call to "system_dependent".
Error in matlabpool>iIsOnClient (line 73)
onclient = ~system_dependent('isdmlworker');
Error in matlabpool>iVerifyJava (line 64)
if iIsOnClient()
Error in matlabpool (line 10)
iVerifyJava();
After some research and sleepless nights, I've found out that one has to settle the things down with the "Cluster Profile Manager". But I never did have the opportunity to see it working either. Here is what I get after clicking Cluster Profile Manager from Parallel panel :

After getting this message, the Cluster Profile Manager pops up, but doesn't really shows anything besides "wait" sign. I've checked my Distributed Computing Licence and that too is looking fine.
license checkout Distrib_Computing_Toolbox
command returns 1.
By the way, there is another error message which I suspected to have a connection with my problem of some kind. I get this in every MATLAB start:
Error using feature
Feature isdmlworker not found
Error in matlabrc (line 187)
if ~(ismcc || isdeployed || feature('isdmlworker')) && usejava('jvm')
In addition to all of those; I get this message whenever I try to open "Parallel Preferences" from Environment tab :

at com.mathworks.jmi.NativeMatlab.dispatchMTRequests(NativeMatlab.java:440)
I've tried to find the function system_dependent.m but it doesn't seem to exist. Other common spots of the errors I get, the function "feature.m", the option "isdmlworker" are other mysteries that I couldn't find any kind of information about.
I really appreciate if anyone can help me with the problem I've encountered starting MATLAB's distributed computing system.
Edit: I'm working on an Ubuntu 14.04 and my MATLAB version is R2014a.
This appears to be an issue with your specific installation of Ubuntu 14.04. It is possible though that it relates to how matlabpool spawns worker threads in R2014a given that the error occurs in com.mathworks.jmi.NativeMatlab.dispatchMTRequests().
matlabpool has been tested to work without issue on Ubuntu 15.04 and 15.10. It may not be an ideal solution but upgrading Ubuntu to 15.04 or 15.10 and reinstalling MATLAB R2014a should resolve the issue.
I just install "SFCGAL". When I use "ST_3DIntersection", It get below error:
ERROR: attempt to redefine parameter "postgis.backend" SQL state:

How can I fix?
I already saw http://postgis.net/docs/postgis_installation.html, but I do not know how should I do.
SFCGAL require to at least CGAL (Geospatial Data Abstraction Library) 4.1 and I already dose not install that. It has provided on : http://trac.osgeo.org/gdal/wiki/DownloadSource
