Ubuntu
software-center package

software-center can not find apache2 and many packages

Asked by SAITOH Akinori

Recently. I installd ubuntu 11.10 to 2PCs. Old dell dimension2400C and new white-box(shop made) PC.
The softwarte-center version 5.0.2 on OLD dell PC seems works well.
But software-center on New PC has a trouble.
On new PC, I invoked software-center I searched apache2. There is nothint match to "apache2".
So I inspected difference between two PCs.

On DELL 2400c, software center says there are 36,075 items.
On NEW pc, software center says there are 3,707 items.

I compared "software source" configuration between two PCs, and I found nothing differ.

I typed
apt-cache pkgnames |grep apache2
and I found apache2 there. So I think underlying apt system works well.

and i tried somecommands. For example,

  apt-get update
  apt-get upgrade
  apt-get remove software-center ; apt-get install software-center
  apt-get purge software-center ; apt-get install software-center

but cound not fix software-center

If by software center you mean the simplified interface. I cant find it either however try opening a terminal (CTRL-ALT-T)

and type

sudo apt-get install apache2

It will ask for your password and should work.

 If not re-open this question with the full output of the command by selecting "Edit/SelectAll" from the terminal menu then "Edit/Copy". Finally post that here

Thank you.
I already installed apache2 with apt-get command.
But I still want to solve the software-center trouble.

Yesterday, a novice student installed ubuntu 11.10 to another new machine. And software-center trouble occure again.
I wonder he gave something wrong input in installation.
