Can't Access newly installed redis(5.0.5) on Ubuntu 19.10

I newly installed Ubuntu 19.10, and installed redis with sudo apt install redis-server(5.0.5).
And started sudo systemctl start redis.
Executed redis-cli, then I got Could not connect to Redis at 127.0.0.1:6379: Y
The last 1 charactor (Y in this case) is different each time.
I just installed with using apt and didn't change any configs.
Is there any bugs or something I missed? please help me.
I tried to install from source code (5.0.7).
It works.

Terminal command in fedora

What does the yum and -y means
yum install httpd -y
new to fedora. please guide me.
the above code will install Apache server in fedora
yum is a software package manager that installs, updates, and removes packages on RPM-based systems. It automatically computes dependencies and figures out what things should occur to install packages. yum makes it easier to maintain groups of machines without having to manually update each one using rpm.
-y means that we did't want to gave yes to install any package (here httpd)
httpd installs apache web server

Please advise
You're missing pre-requisites. Perhaps there are more, but the one you're referred is because of missing X-Windows subsystem. Easiest just to invoke:
$ sudo apt install -y xterm
I hope it will help,

Amazon web services and ubuntu 10.04 ec2 instance

I have created ubuntu 10.04 ec2 image and now I need to install tomcat apache and jdk6 on my instance but whenever I use the command sudo apt-get install sun-java6-jdk or sudo apt-get install tomcat6 admin or sudo apt-get install ec2-api-tools
Package ec2-api-tools is not available, but is referred to by another package.

Package ec2-api-tools is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package ec2-api-tools has no installation candidate
Another option is to add their official repository to apt - this will provide you up to date AWS tools:
sudo apt-add-repository ppa:awstools-dev/awstools
sudo apt-get update
sudo apt-get install ec2-api-tools -y
This is extremely useful for farther releases and and for up to date official bug fixes etc. just by running the usual
sudo apt-get update
sudo apt-get upgrade -y
Ubuntu doesn't have the Sun JDKs available by default so in /etc/apt/sources.list uncomment:
deb http://archive.canonical.com/ubuntu maverick partner
deb-src http://archive.canonical.com/ubuntu maverick partner
and then:
sudo apt-get update
sudo apt-get install sun-java6-jdk
ec2-api-tools requires the multiverse lines in sources.list to be uncommented first (remember to apt-get update also).
I am a bit confused, if you just want to install Java and Tomcat, why are you also trying to install the ec2 tools?
In any case, I also want to mention the free BitNami Cloud Tools installer (disclaimer: I am one of the developers). It includes the JDK and all EC2-related tools. We keep it fairly up-to-date and can run as a regular user.
