[Bug 1241660] Re: update-manager fails when upgrading from 13.04 to 13.10

[Stephen Weber]

Jakub,
I cannot thank you enough. Your instructions solved the problem. I saw 
that the problem was with /tmp but I tried changing the folder attribute 
by adding an "x" for all users, but that did not work.
Thanks again.

Should the bug be closed? How will others see your solution? Can Ubuntu 
issue that exec command while upgrading?

This was my first "bug" report.

Title:
  update-manager fails when upgrading from 13.04 to 13.10

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Confirmed

Bug description:
  AMD64 upgrading from 13.04 to 13.10. In Terminal I type "update-manager -d", click on "Upgrade", authenticate my password, click on "Upgrade" again at the "Welcome to Ubuntu 13.10 'Saucy Salamander" window. A window pops up titled "Downloading Release Tool" and then disappears after file 2 message. Nothing happens.
  Here is the error message text that appears in the Terminal window:
