Always best to start a new thread - especially if marked solved - you'll get better responses..

Looks like you have 2 installs/updates trying to occur at the same time.
If you have something installing and trying to update, you'll need to wait/cancel the install.
Close anything open like synaptic.

Else a reboot should close everything - then relaunch updates...
