It shows GPT corrupted, should I be concerned?

[Confused_nerd]

First of all, I use linux mint 20.1 ulyssa, but i decided to try out tails os.
So i followed instructions here. But when I was live booting from USB stick, I began reading the text it shows, and the first line it said
CAUTION: GPT corrupted, using it anyway. Recommend using encrypted drives.
or something like that....
What should I do?

Okay guys I think the problem is solved(it doesn't exist anymore....).
Because when I rebooted, it didn't show that caution message, instead it showed this

So I guess it's gone.

Probably it was either a hiccup or (more likely, given the output on that screenshot) Linux automatically fixed the problem for you.
