New install of Linux Mint 12, installed one ppa (Jupiter from webupd8.org), but disabled it to debug. I'm new to Linux Mint (converted from Ubuntu), and is mostly happy, but this seems like bugs...
This is what happens:
MintUpdate (the update tool) shows new updates that are available. I click Install updates, but instead of installing updates, the application just closes. The shield icon shows no updates for a few seconds (blank shield) and then is back with updates (blue "i").
So I tried synaptic, but Synaptic just flashes, and then quits. Similar to this Ubuntu bug: https://bugs.launchpad.net/synaptic/+bug/607605, but I don't have any accesibility features enabled so the workaround doesn't work (might be a similar but different bug).
Apt-get works fine though, as does Software manager.
