5 or so years back tails had the vulnerable electrum for some time
So it’s better to have it downloaded from the website first and then use it on tails (offline)

However, it might still work better. Like when you dig up the capsule with a stick from a secret location in deep swamps, boot the shit up and update everything before you proceed 😂
