I have run arduino 8.12, 8.14--it runs fine on my linux mint machine. However, updating to 8.15 gives an error when trying to run:
arduino-1.8.15/java/bin/java: cannot execute binary file: Exec format error
I re-downloaded x86-64 bit several times, 8.15 always fails, but 8.14 downloads and runs fine. I uninstalled, re-downloaded 8.14 to see if this was a pilot error, and re-installed. 8.14 runs fine. Then I uninstalled, redownloaded 8.15, installed--but still get that error. I repeated the same process with the nightly build. It works fine. I checked for forum entries with the same problem, but I dont see anyone else having this problem.
What's different about 8.15 that will give the exec format error?
