I tried to tab complete something and I guess it wasnt there. I know you are not supposed to set the permissions to /etc/ like that, but my permissions seem to be all messed up. whoami prints out cannot find name for user ID 1002 and I cannot cd into /etc/ anymore. passwd and shadow use 640 and 644 so I am not sure why this is a problem. Regardless, is there any way to fix this?
The command run was sudo chmod 644 /etc/
I have no name!@vpn-server:/$ whoami
whoami: cannot find name for user ID 1002
I have no name!@vpn-server:/$ cd etc
bash: cd: etc: Permission denied
I have no name!@vpn-server:/$ ls -al etc

First off all your question is unclear. but still see this...
your /etc directory permission is 644 ie:chmod 644 /etc/
To change Directory execute permission is required
That's why you are getting this error
I have no name!@vpn-server:/$ cd etc
bash: cd: etc: Permission denied
so change the permission to chmod 755 /etc
2nd thing ls -al showing this type of output (d????????? ? ? ? ?) because
I have no name!@vpn-server:/$ ls -al etc d????????? ? ? ? ? ? . d????????? ? ? ? ? ? .. d????????? ? ? ? ? ? acpi -????????? ? ? ? ? ? adduser.conf
To long list a directory read and execute permission is required for directory.
For below error just post /etc/passwd file entry for the id 1002
I have no name!@vpn-server:/$ whoami
whoami: cannot find name for user ID 1002
If the permissions were set on /etc itself to be 644 then just type this: chmod 755 /etc
If the permissions were set recursively... you've got a much deeper problem than just that.
