[Bug 929910] Re: Software Center and Update Manager will not start after downloading Full Circle Magazine

[Frederick L Shope]

I found that the file

 /etc/apt/sources.list.d/private-ppa.launchpad.net_commercial-ppa-
uploaders_fullcircle-issue-56_ubuntu.list

only had root read permission, unlike the rest of the files in that
directory. When I added universal read permission, the software center
and the update manager started running again. This solved my problem.

My original bug report is probably inappropriate, but perhaps the
default permissions for the above file need to include universal read
permission.

Sorry for any inconvenience here.

My problem is solved.

Title:
  Software Center and Update Manager will not start after downloading
  Full Circle Magazine

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  After a routine software update via the update manager and after
  downloading Full Circle Magazine, I found that neither the software
  center nor the update manager would start when clicked on the
  launcher. The software center seemed to have hung during the Full
  Circle Magazine install, and I killed it after about 15 min.
  Afterwards, Full Circle Magazine opened OK and seemed to readable.

  The update manager does report the following error message:

  "Could not initialize the package information
  An unresolvable problem occurred while initializing the package information.
  Please report this bug against the 'update-manager' package and include the following error message:

  'E:Opening /etc/apt/sources.list.d/private-ppa.launchpad
  .net_commercial-ppa-uploaders_fullcircle-issue-56_ubuntu.list -
  ifstream::ifstream (13: Permission denied)'"

  I tried both warm and cold reboots.

  I tried running 'ubuntu-bug update-manager' in terminal, but only
  received the following message:

  "Could not determine the package or source package name."

  I also tried running ubuntu-bug with the process ID for the update
  manager from the system monitor, but just received the following
  message.

  "The specified process ID does not belong to a program."

  All of the above error conditions are repeatable.

  I am reporting this as bug per instructions from the above error
  messages.

  Thank you.
