Re: Stuck at scheme prompt when booting

[coralgoat--- via <help-guix@gnu.org>]

I have some more information to add to my initial message.

I have opened the computer to make sure the hard drive has a good
connection to the motherboard and it does.

I have also tried typing `,bt` at the "scheme@(guile-user)>" prompt
the output is included below.  Note  there is a solid white square 
single character symbol in the output and I am representing it as
 "***" in the output below.

The line in the output that catches my attention is:
"1 (copy-file "/etc/static/resolv.conf" "/etc/resolv.conf")"
This catches my attention because I took this computer to second
location where I tried connecting to a WiFi network.  I was getting
domain name resolution errors and was not able to connect to the
internet.  I resolved the domain name resolution errors by doing 2
things:
1) editing /etc/resolv.conf changing it to a single line that set a
   specific nameserver
2) I ran this command `chattr +i /etc/resolv.conf`
After doing these two things the internet connection was okay.

When I was done in the second location I powered off the computer
and moved to a third location and when it tried to turn on the
computer in the third location I was stuck at this scheme prompt.

I think that if I ran the command `chattr -i /etc/resolv.conf` it
might fix the problem and allow the system to boot however I get an
error when I try typing that at the scheme prompt.

Any suggestions on how I should get a Linux console terminal so I can
enter the `chattr -i /etc/resolv.conf` command?

I could try booting an operating system in memory and then use a disk
encryption program to decrypt the hard drive with my passphrase and
then run `chattr -i /etc/resolv.conf`.  What disk encryption program
should I use to decrypt the hard disk?

Thank you
