failed to upgrade app_A via Software Centre if there is app_B depends on app_A

[nickwang]

On Ubuntu 12.04,

installed app_A and app_B, app_B depends on app_A
double-clicked new app_A to do upgrading, however Software Centre gave prompt that upgrading was failed because app_B depends on app_A.

How to resolve this issue if I would like to upgrade to newer app_A without uninstalling app_B ? Thanks !

Hi, what do you mean by "double-clicked new app_A to do upgrading"? Double-clicked where?

Hi Matthew ,
Thank you for your response !
I mean I double clicked the .deb files on local machine, then Software Center will pop-up and take up the install/upgrading process, right ?

The Software Center seems to do dependency checking first located in /var/info/dpkg/status. The install will fail if other app depends on app_A. The scenario is as below and hope it helps.
1) install app_A
2) install app_A_patch that depends on app_A
3) install new version app_B ( the .deb file is on local and user tyies to double-click it to do upgrading)
4) Software Center pop-ups and gives prompt that "Breaks existing dependency ......" and upgrading failed

I wonder why I can use dpkg tool to do upgrading, like 'sudo dpkg -i app_B' and seems dpkg can handle the dependency stuff and do upgrading for me. Thanks again !

Hi,

I want to explain the scenario below in case it brings any confusion. Please see blue.
Scenario:
1) install app_A
I installed app_A by double-clicking the .deb file I got on local machine
2) install app_A_patch that depends on app_A
I got another .deb that can patch app_A, which I named it 'app_A_patch'. If you run 'sudo dpkg -l | grep app_' , you will see two records -- 'app_A' and 'app_A_patch' both installed.
3) install new version app_B ( the .deb file is on local and user tyies to double-click it to do upgrading)
Now I have a new version of app_A (it should not be named app_B, maybe just NEW app_A here)
4) Software Center pop-ups and gives prompt that "Breaks existing dependency ......" and upgrading failed
I assumed Software Center could install new app_A for me. I can choose to upgrade the app_A_patch later or uninstall it if I want. Dpkg could do this for me whereas Software Center can't.
