I have a problem in lfs s2

unlocks for this week all used

You will have to wait till Friday, when the unlocks are renewed.

Otherwise, email the LFS Tech, and ask them if they can add an unlock to your account.

Contact them at: https://www.lfs.net/?page=mailus

if u ask the devs politely im sure they will let u have 1 more update, u get 2 Fridays.
