Question

I have follow all the post but unable to solve this problem:

By mistake I deleted the /usr/bin/java. After installing many time m still getting this error.

After running update-alternatives --display java I'm getting:

update-alternatives: error: no alternatives for java

Please clarify. When do you get this error? How have you tried to fix it exactly? — Zanna, Jun 02 '17 at 19:10

Please [edit] your question to include the output of update-alternatives --display java — steeldriver, Jun 02 '17 at 19:14
What does dpkg -S /usr/bin/java says? If it shows the package name, try sudo apt-get purge <package>, then install it again. — Hi-Angel, Jun 02 '17 at 20:55
@Hi-Angel: Almost. sudo apt-get install --reinstall <PACKAGE> would be better. — David Foerster, Jun 03 '17 at 07:42
@DavidFoerster I just didn't find in https://packages.ubuntu.com/ a package providing /usr/bin/java, so I assumed it's something dowloaded e.g. from Oracle's site. In this case I don't think --reinstall would help (unless dpkg cached the package?). — Hi-Angel, Jun 03 '17 at 10:49
@Hi-Angel dpkg -S /usr/bin/java shows "no path found matching pattern /usr/bin/java — Gaurav Singh, Jun 03 '17 at 14:09

In a terminal, run the following:

update-java-alternatives -l | awk '{ print $1; }'

Pick one of the listed options, and run:

sudo update-java-alternatives -s the-option-you-chose

after running update-java-alternatives -l | awk '{ print $1; }' output what i get is java-1.7.0-openjdk-amd64 and then i run sudo update-java-alternatives -s java-1.7.0-openjdk-amd64 i get update-java-alternatives: directory does not exist: /usr/lib/jvm/java-1.7.0-openjdk-amd64 – Gaurav Singh Jun 04 '17 at 05:12

In that case, it's likely that OpenJDK itself was removed. To reinstall, assuming you're using Ubuntu 14.04, use either sudo apt-get install --reinstall openjdk-7-jre or sudo apt-get install --reinstall openjdk-7-jdk. – Chai T. Rex Jun 05 '17 at 02:18
