引导错误包含org.eclipse.core.runtime包，但不是osgi.bundles出现故障

Question

I attempted to install PyDev running Eclipse as my usual user. This failed with errors about not being able to write to the file system, so I restarted Eclipse as root and followed the usual steps: Help -> Add Software . This instance of Eclipse already had the Perl dev add-on that has worked for years, in case this is relevant.

I have tried what is in "Unable to acquire application service" error while launching Eclipse .

This is running in a VM running an Ubuntu 16.04 guest OS with 4.15.0-43-generic Linux kernel.

java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.16.04.1-b12)
OpenJDK Server VM (build 25.191-b12, mixed mode)

Here is the log when I try to run Eclipse and run ./eclipse -clean

Answer 1

I just reinstalled eclipse and installed EPIC and PyDev. Note that eclipse 3.8 requires the right PyDev site for 4.5.5, not the default.
