When there is a syntax error in an apt sources.list file a dialog is displayed with something along these lines:
"""
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:Type 't/screenlets/ppa/ubuntu' is not known on line 3 in source list /etc/apt/sources.list.d/screenlets-ppa-oneiric.list'
"""
This is usually a user error and shouldn't be reported as a bug. update-manager should handle this situation better and showing a clear message about how to fix that situation instead.

3. A dialog is displayed with something along these lines:
------------
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:Type 't/screenlets/ppa/ubuntu' is not known on line 3 in source list /etc/apt/sources.list.d/screenlets-ppa-oneiric.list'

Besides the duplicates marked here, there are dozens of bug reports with particular examples of malformed sources.list, such as bug 128775, bug 163933, bug 164135, bug 176253, bug 183861, bug 241154, bug 311399, bug 350373, bug 358587, bug 416872, bug 432318, bug 470589, bug 617232, bug 617998, bug 677698, bug 728258, bug 753253, bug 799600, bug 830588, bug 835258, bug 879221, bug 880661, bug 886641, bug 890138, bug 927987, bug 947296, bug 981357, bug 1008359, bug 1009618, and bug 1063099.
Often these bug reports are marked as Incomplete or Invalid, or converted into questions, on the grounds that the user must have edited sources.list themselves. But Ubuntu should be robust enough to repair problems like this itself. |
