I installed Krita on my Ubuntu 20.04.6 LTS. I don't remember how I installed it. It's a very complicated software and my use case is very simply. Therefore I wish to uninstall it.

For uninstalling it I issued the command in the terminal

$ sudo apt-get remove krita

but my terminal replied

Package 'krita' is not installed, so not removed

I even tried

$ sudo apt-get purge krita-data

But that doesn't work either.

How do I uninstaller this stickler from my system.

I have installed Tomcat 7 on Ubuntu 12.04 LTS which runs on an Amzon EC2 instance. Now I wish tomcat should restart automatically on system reboot.

I read this blog which suggest adding below script to /etc/init.d/tomcat7:

# Tomcat auto-start
#
# description: Auto-starts tomcat
# processname: tomcat
# pidfile: /var/run/tomcat.pid

case $1 in
start)
sh /usr/share/tomcat7/bin/startup.sh
;;
stop) 
sh /usr/share/tomcat7/bin/shutdown.sh
;;
restart)
sh /usr/share/tomcat7/bin/shutdown.sh
sh /usr/share/tomcat7/bin/startup.sh
;;
esac 
exit 0

and issue the following commands: 

sudo chmod 755 /etc/init.d/tomcat7

sudo ln -s /etc/init.d/tomcat7 /etc/rc1.d/K99tomcat

sudo ln -s /etc/init.d/tomcat7 /etc/rc2.d/S99tomcat

sudo /etc/init.d/tomcat7 restart

My Questions

  1. The tomcat7 already has script in it, where do we have to paste the suggested script?
  2. Is the suggested procedure correct?

I have installed Ubuntu 12.04 LTS on Amazon EC2 instance along with Tomcat and MySql. Tomcat, Java and MySql packages were available along with Ubuntu and I didn't have to download them.

Now I wish to install Percona Xtrabackup to my Server.

Now, how do I find if a certain package is already available with the installation or I have to install it externally?
