apt-get install libxrender1:i386 libxtst6:i386 libxi6:i386

helped me get this resolved.

I have installed in a 64 bit system also i386.

    This worked for me where the other answers would not. Thanks. – a coder Aug 11 '17 at 20:34
  • For sure this is correct answer if you're running i386 version of JRE or any other software which depends on this set of libs. You always must match architecture between runtime and shared libs. – stamster Feb 9 '18 at 21:16

Check which package contains the file and install it:

$ apt-file search libXext.so.6 
libxext6: /usr/lib/x86_64-linux-gnu/libXext.so.6 
libxext6: /usr/lib/x86_64-linux-gnu/libXext.so.6.4.0
libxext6-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/libXext.so.6.4.0 

So install libxext6:

sudo apt install libxext6

  • sir this method is not working – Ankit_Chaudhary Sep 16 '15 at 12:55
  • What part? The apt-file or apt install? – JdeHaan Sep 16 '15 at 14:37
  • sir i mean above mentioned error is not rectify by this method – Ankit_Chaudhary Sep 16 '15 at 17:56
  • So, is the file actually there? sudo find / -name 'libXext*' – JdeHaan Sep 17 '15 at 10:09

    Could very well be a version conflict in 32-bit vs. 64-bit. Please check out this question on stackoverflow: stackoverflow.com/questions/24543014/… – JdeHaan Sep 17 '15 at 10:20

I had to install this (on ubuntu 16.04 64 bit) to make oracle-jdk8 work:

sudo apt-get install libxrender1 libxtst6 libxi6

  • I do not know what, but this fixed my problems after trying hundreds of other apt install whatever commands from other answers! – team17 Dec 19 '19 at 10:33
