Continuing to have difficulties with upgrades.
I get a notification that one or several programs need to be upgraded. When I tell it to install, it says that it would be replacing an existing program, which I knew.
And then it says:
"Application not installed"
"An existing application package by the same name with a conflicting signature is already installed."
This is not the first time or the first program on which this has happened. I have tried, when receiving the 'replace' notice, deleting the program first. When I do that, the update is no longer available. And after having the upgrade installation fail, there is no trace of the upgrade program.
