I am trying to use ELAN on a new Ubuntu 20.04 system. I downloaded the 6.3 tar.gz archive files listed for Linux. However, whenever I try running it, I get the error messages:
“Error: could not find libjava.so
Error: Could not find Java SE Runtime Environment.”
I made sure JRE is installed and working. There was a previous thread facing the same issue on ELAN 5.9 (I’m not allowed to link it), and I tried the solutions offered without success up until building ELAN from the source code. Have others ran into this problem and found an way to fix it in Ubuntu without needing to build from the source code?
Hello,
Yes, it would be good to know if anyone else ran into the same problem and found a solution.
I wasn’t able to reproduce the problem on my Ubuntu 20.04 x64 system then and am not able to reproduce it now. Other suggestions than the ones in the previous post (that you already tried) I don’t have.
Maybe you could try the .deb version? I don’t know why that would work, as I also don’t know why the .tar.gz version doesn’t work on your system.
In principle you don’t need a separately installed JRE; the ELAN distribution includes a JRE which is/should be used when ELAN is launched.

Thank you, the .deb version does work! I didn’t realise Ubuntu was able to run .deb files 
Ok, great. Mystery not solved, but good that the .deb version works!
