PPP install error on Raspberry Pi - raspberry-pi

I am rather new to Linux and have been playing with the Raspberry Pi. I am trying to get a modem I have working with this Pi. I am learning here but any help on how to fix this situation would be great.

I am not quite familiar with the requirements of AWS, but I could run the app locally and without any problem. I just wonder what would be a right configuration for the requirements.txt file in order to avoid the bug.
Thanks in advance.
You have to install postgresql-devel first before you can use psycopg2. You can add the installation instructions to your ebextentions:
packages:
yum:
postgresql-devel: []
or
commands:
command1:
command: yum install -y postgresql-devel
I could solve the error. I have to change psycopg2 by psycopg2-binary as it was suggested by the AWS logs:
If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.
This issue has to be with the particular configuration of the libraries and the specific Linux machines used in AWS.

How to debug the problem not able to translate OID with a new MIB file for UPS-MIB?

On Centos, I ran into the following error:
sudo snmptrap -v 2c -c read localhost '' UPS-MIB::upsTraps
MIB search path: /root/.snmp/mibs:/usr/share/snmp/mibs
Cannot find module (UPS-MIB): At line 0 in (none)
UPS-MIB::upsTraps: Unknown Object Identifier
The above error happened after
Copied UPS-MIB.txt to /usr/share/snmp/mibs
I started snmptrapd:
snmptrapd -f -Lo -Dread-config -m ALL
The version of the Net-SNMP is 5.2.x.
The same procedures work fine with Ubuntu 18.04/Net-SNMP 5.3.7.
I wonder how to debug and fix the problem?
Besides the Net-SNMP version difference, on Ubuntu, I found an instruction to install mib-download-tool, and execute it after the installation of Net-SNMP, and comment out the lines beginning with min: in snmp.conf in order to fix the error of missing MIB's.
However, for the Centos, I had no need and found no such instruction, thus I have not done it yet, as there is no error message of missing MIB's.
The MIB file is downloaded from https://tools.ietf.org/rfc/rfc1628.txt
renamed to UPS-MIB.txt (It seems to me that the name of the MIB file does not matter, as long as it's unique? I tried to use a different names, upsMIB.txt, rfc1628.txt, but it does not help to improve.)
I solved the problem as follows:
manually copied /usr/share/snmp/mibs/ietf/UPS-MIB on an Ubuntu with Net-SNMP 5.7.3 installed to the Centos /usr/share/snmp/mibs/UPS-MIB
then restart the snmpd
by the command:
service snmpd restart
then the OID of UPS-MIB becomes visible and accessible.
Maybe, the version that I downloaded from https://tools.ietf.org/rfc/rfc1628.txt is not suitable??

I am also getting the below warning. Is this related?
WARNING: Layer meson should set LAYERSERIES_COMPAT_meson in its

I'm new to OE coming over from OpenWRT.
For bitbake, I've added the layers for the packages below:
meta-openwrt:- OE/Yocto metadata layer for OpenWRT
superna9999/meta-meson:- Upstream Linux Amlogic Meson Yocto/OpenEmbedded Layer
And tried compiling the nexbox-a95x-s905x image
I think the problem is that /etc/iproute2/rt_protos is provided by base-files which is coming from meta-openwrt as well as from iproute2 package which is coming from other OE layers. its not clear for the image builder which one to use and hence the conflict
You can solve it via defining a iproute2_%.bbappend file in meta-openwrt where this file gets deleted from iproute2 package and preference is given to the one openwrt provides
do_install_append() {
rm -rf ${D}${sysconfdir}/iproute2/rt_protos
}
should help.

Backport installation script for Broadcom 14e4:43ae wifi controller fails

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.

Now I'm trying to install otrs 3.3.6 but I'm get an error as below.
Have I challenges to fix it? Or it is a compatible issue?

I faced the issue because I created otrs user before installation.
