How do i send money out of this wallet now? Do i need to update electrum?
Do you have any backup copy seed or private keys or wallet.dat?
If you have then you can start updating your electrum but don't use the popup window just go directly to
http://electrum.org/ and use the command there to install or update your electrum from Tails OS.
How can you even go about updating electrum on tails OS?
Tails OS is a well-known secured OS based on what I heard it is a Linux based OS which is made for security purposes. So updating electrum is fine the only problem about electrum is that some server is infected and sending you a phishing link by showing up to update your electrum.
(p.s - also, is my laptop and wallet/bitcoins safe? I never followed any links or downloaded anything but its stressful knowing that a phishing scam can appear on my screen when trying to send bitcoin)
Your laptop and wallet is safe just make sure that the electrum wallet you download is directly from correct
http://electrum.org/ website.
Don't forget to backup your private keys and wallet.dat and seeds before you going to update.
