I just downloaded myeclipse-9.0M2-online-installer-linux.run for an Ubuntu 10.10 development environment. On trying to run I get:

scott@gator:~/Downloads$ ./myeclipse-9.0M2-online-installer-linux.run

Scott,

Thanks for the details, I’ll ask our Installer team to take a look at this asap. In the meanwhile, it would appear that there was some sort of permission problem – either the installer was unable to extract into the temp location or for some reason it could not read what was extracted. Does the user you are running the installer as have read / write permissions to the “/tmp” folder?

If you wish to install MyEclipse 9.0M2 in the meanwhile, you can install it using Pulse Explorer, let me know if you need further instructions.

Sorry for the inconvenience caused.

Not a problem Brian – that is why they are milestones, not GA. I’m very confident that my /tmp has the correct permissions – many other things would be broken if they were incorrect. I did try the “offline” installer and it worked just fine so this is an “online” problem only.

Edit – and at a guess, the problem is that I’m using a 64 bit JVM. The line from the installer error:

– Detected JVM architecture: bit
[: 124: =: argument expected

seem to indicate that the shell script for installation didn’t parse something correctly.

[Brian Fernandes]

I’m glad the offline installer worked – that too was an important data point.

We had another look at the online installers and did find a few places where things could potentially go wrong and a few places where error reporting could be improved too. Both improvements will be added to our GA installers, so your feedback has been very helpful.

If you still have the online installer that you used with you, can you confirm that the MD5 sum of that file is: a0cf50fb9d942360a094c715b7ab0853
