Can't install anything from Software Manager [SOLVED]

[silvius_discipulus]

Hola mis compañeros de Mint,

I have a problem that's pretty easy to describe. When I try to install anything from Software Manager in LM12, nothing happens. The install button disappears after I click install, but no ongoing actions occur, it just sits there until I exit. The first thing I tried to install was the UbuntuOne client, just to see if it might work. Then I tried deluge, but it failed in the same way.

Reinstall the Software Manager and see if it gets fixed.
Open terminal and type in "sudo apt-get install --reinstall mintinstall"

This happens to me occasionally as well. It's pretty easy to fix. Close the Software Manager, open terminal -- type "sudo apt-get update" and hit enter. After that, things should work as expected.

True lol, because the repos get updates regularly and if you don't update the packages list, it won't recognize where to get those packages from.
I'm surprised I didn't think of that

Still no joy. So far I have tried these in terminal:

sudo apt-get install --reinstall mintinstall

sudo apt-get update

apt update && apt upgrade

All of them seemed to do stuff, but I checked after each one and trying to install from Software Manager still does nothing. Any other ideas?

When I try running mintinstall from Terminal, this is what I see:

$ mintinstall
/usr/lib/linuxmint/mintInstall/mintinstall.py:252: SyntaxWarning: import * only allowed at module level

Would that warning have anything to do with the problem I am experiencing?

After searching for lots of different keywords, I finally found the solution in an older thread on this forum. If you experience the same problem I did, do this in Terminal:

Code: Select all

 sudo mv /var/lib/apt/lists /var/lib/apt/lists.old
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get update

And Software Manager will start responding again. Thank you to everyone who gave their input on fixing this.

Thanks for the continued effort with this problem.
This method did make the software manager hang around for a little longer than usual, but ultimately, still crashed.
Not "SOLVED" on this machine.
