Ive been running the Linux wallet on Ubuntu 16.04 for a while without problems. But starting yesterday Im getting transaction failed errors when trying to send to an exchange. I havent updated Ubuntu or the wallet

What wallet version are you running?
You should be on version 2.0.1.7

Compare your block number with the block explorer and make sure they match.

Be sure to have backup copies of the wallet.dat before beginning.
Start the wallet, make sure it is fully synced with the network
Click on Help, click Debug Window, click the Console tab,
beside > type repairwallet , hit Enter key.
This should repair the wallet , check your balance under the Overview tab to see if it is accurate.
If the Balance is still not correct, close the wallet.
From the COMMAND LINE or Change the desktop shortcut so you run the following then restart the zeitcoin-qt.exe -rescan, this will also take some time.

Cool
