Unable to locate package java package

Unable to locate package oracle-java7-installer [Ubuntu 13]

Was installing Java today, this is an easy install thanks to “ ppa:webupd8team/java “, but when I tried it was not working, but has worked for me all this while.

Little goggling around found me a solution. Here is full conversation if you wanted to have a look http://ubuntuforums.org/showthread.php?t=2048793

Installing JAVA on Ubuntu is simple. Do the below to add the repository and run the below command ‘sudo apt-get install oracle-java7-installer’ to install.

Error.

 ahmed@ubuntu:~$ sudo add-apt-repository ppa:webupd8team/java ahmed@ubuntu:~$ sudo apt-get update ahmed@ubuntu:~$ sudo apt-get install oracle-java7-installer ahmed@ubuntu:~$ sudo apt-get install oracle-java7-installer Reading package lists. Done Building dependency tree Reading state information. Done E: Unable to locate package oracle-java7-installer 

Solution.

 root@ubuntu:~# echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" > /etc/apt/sources.list.d/webupd8team-java.list 

 root@ubuntu:~# echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main" >> /etc/apt/sources.list.d/webupd8team-java.list 

 root@ubuntu:~# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys EEA14886 

 root@ubuntu:~# apt-get install oracle-java7-installer root@ubuntu:~# exit 

 ahmed@ubuntu:~$ ahmed@ubuntu:~$ java -version java version "1.7.0_60" Java(TM) SE Runtime Environment (build 1.7.0_60-b19) Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode) ahmed@ubuntu:~$ 

I just update / adding the new package to repos.
And added a key to keyserver that it.. 🙂

Below are the things we need to do to make it work.

1. sudo su
2. echo «deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main» > /etc/apt/sources.list.d/webupd8team-java.list
3. echo «deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main» >> /etc/apt/sources.list.d/webupd8team-java.list
4. apt-key adv —keyserver keyserver.ubuntu.com —recv-keys EEA14886

Zabbix History Table Clean Up

Zabbix history table gets really big, and if you are in a situation where you want to clean it up. Then we can do so, using the below steps. Stop zabbix server. Take table backup — just in case. Create a temporary table. Update the temporary table with data required, upto a specific date using epoch . Move old table to a different table name. Move updated (new temporary) table to original table which needs to be cleaned-up. Drop the old table. (Optional) Restart Zabbix Since this is not offical procedure, but it has worked for me so use it at your own risk. Here is another post which will help is reducing the size of history tables — http://zabbixzone.com/zabbix/history-and-trends/ Zabbix Version : Zabbix v2.4 Make sure MySql 5.1 is set with InnoDB as innodb_file_per_table=ON Step 1 Stop the Zabbix server sudo service zabbix-server stop Script. echo «——————————————» echo » 1.

Cloudera Manager — Duplicate entry ‘zookeeper’ for key ‘NAME’.

We had recently built a cluster using cloudera API’s and had all the services running on it with Kerberos enabled. Next we had a requirement to add another kafka cluster to our already exsisting cluster in cloudera manager. Since it is a quick task to get the zookeeper and kafka up and running. We decided to get this done using the cloudera manager instead of the API’s. But we faced the Duplicate entry ‘zookeeper’ for key ‘NAME’ issue as described in the bug below. https://issues.cloudera.org/browse/DISTRO-790 I have set up two clusters that share a Cloudera Manger. The first I set up with the API and created the services with capital letter names, e.g., ZOOKEEPER, HDFS, HIVE. Now, I add the second cluster using the Wizard. Add Cluster->Select Hosts->Distribute Parcels->Select base HDFS Cluster install On the next page i get SQL errros telling that the services i want to add already exist. I suspect that the check for existing service names does n

Access Filter in SSSD `ldap_access_filter` [SSSD Access denied / Permission denied ]

Access Filter Setup with SSSD ldap_access_filter (string) If using access_provider = ldap , this option is mandatory. It specifies an LDAP search filter criteria that must be met for the user to be granted access on this host. If access_provider = ldap and this option is not set, it will result in all users being denied access. Use access_provider = allow to change this default behaviour. Example: access_provider = ldap ldap_access_filter = memberOf=cn=allowed_user_groups,ou=Groups,dc=example,dc=com Prerequisites yum install sssd Single LDAP Group Under domain/default in /etc/sssd/sssd.conf add: access_provider = ldap ldap_access_filter = memberOf=cn=Group Name,ou=Groups,dc=example,dc=com Multiple LDAP Groups Under domain/default in /etc/sssd/sssd.conf add: access_provider = ldap ldap_access_filter = (|(memberOf=cn=System Adminstrators,ou=Groups,dc=example,dc=com)(memberOf=cn=Database Users,ou=Groups,dc=example,dc=com)) ldap_access_filter accepts standa

How to Fix “unable to locate package openjdk-8-jdk” in Ubuntu Server

By default, Ubuntu Server does not come with OpenJDK installed. OpenJDK must be installed manually from the repository.

However, sometimes even after running “sudo apt-get update”, the OpenJDK package is not found on the repository, even though it should be available for installation. The installation will fail with the following error:

[email protected]:~/Java$ sudo apt-get install openjdk-8-jdk Reading package lists. Done Building dependency tree Reading state information. Done E: Unable to locate package openjdk-8-jdk

How to Fix “unable to locate package openjdk-8-jdk” Error

If such an error happened to your Ubuntu Server installation, do not worry! You do not need to rebuild the server installation from scratch; you can install OpenJDK from another repository such as the Debian Jessie repository.

The installation from another sanctioned repository, like the Debian one, will not break your existing installation and repository setup. In fact, OpenJDK 8 from the official Debian repository is 100 percent compatible with Ubuntu Server since Ubuntu Server is based on Debian. If you use Ubuntu 16.04, follow these steps to get started.

First, you need to install the Debian Archive keyring package by issuing the following command:

sudo apt-get install debian-keyring debian-archive-keyring

Then, issue the following command (you can replace nano with vim or other text editors you like)

sudo nano /etc/apt/sources.list.d/debian-jessie-backports.list

In the text file, enter the following string:

deb http://httpredir.debian.org/debian/ jessie-backports main

Then, save the text file and quit nano. Afterward, you need to create another text file using this command:

sudo nano /etc/apt/preferences.d/debian-jessie-backports

Paste this string into the new text file:

Package: * Pin: release o=Debian,a=jessie-backports Pin-Priority: -200

Afterward, save the text file and quit Nano. Enter the following command to upgrade the package database:

And finally, issue the following command to install OpenJDK from the Debian Jessie repository:

sudo apt-get -t jessie-backports install openjdk-8-jdk

We are a bunch of people who are still continue to learn Linux servers. Only high passion keeps pushing us to learn everything.
