I am new on linux distribution and I have a problem I did not manage to fix. I am sorry if the problem is easy to fix... I tried to update my debian computer with apt-get update... But at the end, I obtained the following thing :
.W: Erreur de GPG : http://repo.mongodb.org jessie/mongodb-org/3.4 Release : Les signatures suivantes ne sont pas valables : KEYEXPIRED 1515625755
I don't know how to fix it... The computer date is correct (it is jeudi 18 janvier).. I checked some forums but it did not really help me...
Thank you in advance !
