Public bug reported: Observed behaviour: the Ubuntu installer slows down to a crawl at the stage of restoring previously installed packages.
The following message is displayed in the installers terminal view: Failed to create sharedmemoryfile /WK2SharedMemory.XXXXXXXX: Permission denied Steps to reproduce: 1. Have an already installed version of 14.04 or 16.04 2. Start the Ubuntu 16.04(.1) installer from desktop installation media 3. Choose to do "something else" instead of installing over or alongside and choose the previous root partition for the new root partition but _don't_ format it. 4. Continue with the installation as usual. 5. Open a terminal and run `top` to monitor the CPU load, at the stage of "restoring previously installed packages" a WebKitWebProcess shows up consuming almost 100% of CPU resources. After Killing it with `killall WebKitWebProcess` the installation continues. This has been reproducible on al laptop for 14.04 and 16.04 as well as VirtualBox VMs with 14.04 and 16.04 preinstalled. Installing a package like lyx (pulls in tex dependencies and many megabytes of data) might help triggering this bug but I also encountered it without lyx preinstalled during tests.
