I am trying to install Eclipse 2020-06 into an Ubuntu 18.04 VM. I've been able to download the installer, and the install starts, but multiple times in a row now it fails with the following stacktrace:

Does it fail the same way repeatedly? If so, perhaps something corrupted was cached. You can use the Bundle Pools dialog's Clear Cache... to clear them so that they're downloaded from the internet again.

I've managed to get past this, but I'm only hitting another symptom of the same problem. I had been attempting to optimize space usage on the VM by having the ~/.p2 directory be a symlink to the corresponding directory on the Windows host (through a shared folder), but I had given up on that and didn't realize that that relationship was encoded in the ~/.eclipse directory somehow. I've tried to delete all vestiges of that, but it still seems to reappear. I'm going to post a new note with updated information.
