Installing Broadcom b43 driver offline on HP Pavilion dv6.

My friend installed Ubuntu 18.04 on HP Pavilion dv6 but Wi-Fi did not work on the Broadcom wifi adoptor. Moreover Ethernet did not work.

I downloaded following files on my mobile phone and sent to him on WhatsApp:
b43-fwcutter_019-3_amd64.deb from packages Ubuntu 18.04.
broadcom-wl-5.100.138.tar.bz2 from iwfinger.com

This friend was not familiar with Linux commandline and I had to make many calls and WhatsApp messages to execute following instructions.
Keep the files on Home folder and open terminal.
$ sudo dpkg -i b43-fwcutter_019-3_amd64.deb
$ tar xfvj broadcom-wl-5.100.138.tar.bz2
$ sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o

Reboot.
It works.

Using Podman Container on Endless OS to get Finance::Quote.

Endless OS came pre-installed on my acer aspire3 bought last year I started liking it but I had installed Ubuntu 18.04 in dual boot because I was not familiar with flatpak apps only type of Linux Distributions. Moreover, the main problem I noticed that the flatpak version of Gnucash did not have Finance::Quote which updates NAV of ny investments on daily basis.

I posted about this requirement on Endless OS Community and one of their developer posted on Github asking what was the program to include Finance::Quote on the flatpak version last December.

Recently I posted about this problem and I was introduced to Podman through which I built a Container with Ubuntu 19.10 mini ISO (75.2 MB).
Podman is a Cli only utility.

mkdir ~/sharing This directory will share the files on the host with Container.

podman image pull ubuntu:19.10
podman run --interactive --tty --name mycontainer\
--volume /tmp/.X11-unix:/tmp/.X11-unix \ --env DISPLAY --device /dev/dri --device /dev/snd --device /dev/input \ --volume /etc/localtime:/etc/localtime:ro \
--volume /sysroot/home/$(whoami)/sharing:/mnt ubuntu:19.10

root@ca50d6597e9c:/#
Then I created a User (Username same as on Endless OS)
root@ca50d6597e9c:/# useradd -d /home/username -s /bin/bash username mkdir -p /home/username chmod -R 700 /home/username chown -R username:users /home/username

exit

Next I installed Gnucash in the Container:
$ podman start mycontainer
$ podman exec --interactive --tty mycontainer /bin/bash
root@ca50d6597e9c:/# apt update
# apt install gnucash

Gnucash got installed pulling all its dependencies
# exit

Before running the Container I had put the file myaccount.gnucash in the ~/sharing folder.

Next I had to run Gnucash in the Container using the Display of Endless OS.
$ podman start mycontainer
$ xhost +
$ podman exec --interactive --tty --user $(whoami) --workdir /home/$(whoami) mycontainer/bin/bash

Username@ca50d6597e9c:/$ gnucash /mnt/myaccount.gnucash
Gnucash opened using Display of host.
I updated the NAVs through Tools/Price_Deskto/Get_Quotes

exit
$ podman stop mycontainer

I could have updated the NAVs through Commandline also:
Username@ca50d6597e9c:/$ gnucash --add-price-quotes /mnt/myaccount.gnucash

OR
Just typing the following on the host:
$ podman start mycontainer
$ docker exec -it mycontainer gnucash --add-price-quotes /mnt/myaccount.gnucash without using GUI.

My Acer Aspire3 A315-21-43WX is showing strange colours.

NB: I have updated this post on Oct 2, 2019 and replaced the images since the earlier images were screenshots which looked as described on my Laptop but not to others. Today I have taken photos instead of screenshots.
My Acer Aspire A315-21-43WX is showing strange colours. See the Screenshot of the Ubuntu 18.04 Background below:

and notice the light blue instead of white background on the text editor below:

When I type the letters are appearing in violet colour instead of black as I am writing this post.
Thank God the Laptop is under warranty of one year since I purchased on amazon on October 10, 2018.

 I have lodged a complaint to acer, took the Laptop to Service Center yesterday and got it back today. I will give it to them for parts replacement when it arrives at the Service Center. Meanwhile I am using it as it is.

I rooted our old phone Karbonn Sparkle V (Android One).

We had purchased Android one Phone (Karbonn Sparkle V) in Sep 14 when it was launched. It came with Android 4.4.4 (Kitkat) which was updated to Android 6.0.1 (Marshmellow) in 2016. This phone has only 1 GB RAM which was inadequate to run and update Whatsapp and Facebook Lite since it had pre-installed apps Moneycontrol, Snapdeal, OLX which we don't use and occupying memory.

The solution was to remove the pre installed apps which was possible after rooting the phone.

Attempt to root an Android phone has risk of loosing the phone if it becomes un bootable. Since this phone has a resale value of Rs 500/- only I decided to take the risk.

For rooting the phone you need to connect it to Laptop/PC through USB after invoking the Developer options by clicking 7 times on Build number and enable USB de bugging.through it and you have to allow install from Unknown Sources.
You also need to download Android One Toolkit on your Laptop/PC and try. I tried this but could not root the phone.

After further research I came to know that I needed to download Super SU and ThunderZap and copy it to the root of SD Card.

This procedure was described on Youtube.

After making two or three attempts using this procedure I could root the phone.
I confirmed rooting by the app Root Checker.

Then I downloaded SuperSU for granting root permission to the apps and remove the pre installed apps by using System app remover after granting root permission to it.

Now this phone is usable for regularly updating Whatsapp and Facebook Lite.
