# Steps to reproduce:

I start going through the GUI installer and during the install I get these errors:

![memory-leak](https://coinsh.red/u/653Guix-Memory-Leak.jpeg) <https://coinsh.red/u/653Guix-Memory-Leak.jpeg>

Next I enter and get these:

![crypt-error]( <https://coinsh.red/u/Crypt-Error_647_.jpeg>https://coinsh.red/ipfs/QmWkYNpehzGZNeJquZb8ev39SzsQ9crmMfNofAnMKNdz4c <https://coinsh.red/ipfs/QmWkYNpehzGZNeJquZb8ev39SzsQ9crmMfNofAnMKNdz4c>) <https://coinsh.red/u/Crypt-Error_647_.jpeg>

Then after restarting I tried the first couple steps then it halted with these:

# What was expected?

I am not certain what these errors mean. I tried to RTFM but wasn't able to find much.
