apt - How do I remove a malformed line from my sources.list? - Ask Ubuntu


i have unistalled , reinstalled ubuntu software center per info found in similar thread , got same response line 91 or that.

i tried upload screen shot since i'm new won't allow me to. can not figure out how cut , paste have hand type error screen says, both when attempt open software center , nothing happens, when try enter commands terminal uninstall, reinstall, whatever same following:

could not intitialize package information unresolvable problem occured while initializing package information please report t:his bug against 'update-manager' package , include following error message: 'e: malformed line 91 in source list/etc/apt/sources.list (dist parse)  e: list of sources not read.,  e: package list of status file not parsed or opened.

how report bugs? can done this. have searched , says leads me same line error message.

so, don't know how line 91 in source list; tell says. sorry, i'm new this. need find out how there , fix says. not have re partition hard drive , start scratch, i'm looking forward getting problem solved. need able install new software.

some lines broken in sources.list file (or *.list file in sources.list.d/).

edit file mentioned in error fix broken lines.

  1. to this, run command (press ctrl+alt+t open terminal):

    sudo -h gedit /etc/apt/sources.list

    if necessary, replace /etc/apt/sources.list file name.

  2. find lines incorrectly formatted (refer error line number, around point). these examples of correctly formatted lines:

    # comment, marked line starting '#' deb http://site.example.com/debian distribution component1 component2 component3 deb-src http://site.example.com/debian distribution component1 component2 component3

    the url, distribution , components different. not have have 3 components.

    anything doesn't fit format incorrect.

  3. save file , quit text editor. run command in terminal window:

    sudo apt-get update

assuming there no errors, problem fixed. should able run sofware center.

however, while problems software center can solved reinstalling software-center package, cannot, it's possible original problem remain. if case, can post new question it.
