Enjoying Xubuntu Live persistent on Dell Inspiron N4010 P11G

I came to Hyderabad to spend winter. I borrowed Dell Inspiron N4010 3 GB model with Windows 7 Professional for personal use. Before leaving home I had uploaded required Gnucash Files and Libreoffice files to Drive.

I downloaded Xubuntu 20.04 64 bit ISO while working on Windows 7 and installed Rufus to make Live USB with persistence. Making Live USB on Rufus was smooth.

I changed the Boot sequence in BIOS to bring USB drive on top and and booted to Try Ubuntu Install Ubuntu Desktop and choose Try Ubuntu. To remove the Try Ubiuntu/Install Ubuntu option I removed Ubiquity.

After shutdown the system asked for removal of USB. I wanted to remove this irritant and posted on Ubuntuforums. I got the following solution

xubuntu@xubuntu:~$ sudo mousepad /etc/systemd/system/casper-no-prompt.service

I wrote the file and saved it

# see /sbin/casper-stop

xubuntu@xubuntu:~$ ls -l /run/casper-no-prompt
-rw-r--r-- 1 root root 0 Jan 17 15:04 /run/casper-no-prompt

Now I can shutdown safely without removing USB.

I installed Gnucash and Libreoffice was already present.

Live Xubuntu 20.04 is very fast on this 3 GB machine.

Enjoying it.

Income Tax efiling utility and DSC working on Ubuntu Linux.

I am using Linux since Sep 2004 and Ubuntu since July 2005. I was forced to use Windows for Bank of Baroda Netbanking and efiling of Income Tax Return.

Bank of Baroda changed in 2012 and I could use Chromium Browser with JRE 7 on Ubuntu.

Income Tax efiling utility worked only on Windows besides the Digital Signature upload and signing.

Since last two years my CA prepares the xml file of the Income Tax Return but last year I had to use Windows for uploading the xml file using Digital Signatures.

On going through Downloads on Income Tax efiling website I find that besides Excel utility there is Java utility which is having following instructions in Readme.txt
To run in LINUX
Change the ITR.sh file's permission, provide execution permission by executing the following command
> chmod 755 ITR.sh                
run using the command "sh ITR.sh" or ./ITR.sh


This year I find that I could use Firefox with latest JRE 7 on Ubuntu for uploading and signing the Digital Signatures (DSC).

Thanks to the demise of Windows XP, the Income Tax Department had to switch to latest JRE 7 which works on Windows 7/8 as well as Ubuntu 12.04.
