Hi, bbegin -
First off, thank you for this wonderful thread and for sharing your image file. I built a MAME cabinet powered by a PC many years ago. I am now replacing the CRT display with a flat screen, and the PC with a raspberry pi 4. I have installed the June 1st 2021 image and am now experiencing the same issue that jhummel was encountering. Any advice as to how to proceed would be greatly appreciated. I tried some of the steps you suggested to him, but with no luck.
update: I should add that changing the password upon initial start did not work. The system replied "passwd: Authentication token manipulation error". Perhaps this issue is related to the "cannot lock /etc/password" reply when I tried the command sudo usermod -a -G render pi
Hi beernite, thanks!
You mean when you run raspi-config, you get "No wireless interfaces found" message? If so, it may be caused by the fact I forgot to remove some lines from a file.
To check, issue this command:
cat /etc/modprobe.d/raspi-blacklist.conf
Make sure the lines below are
NOT in the file (remove them, if they are there):
# WiFi
blacklist brcmfmac
blacklist brcmutil
EDIT: I double-checked on the image I provide and the lines are not there, so the Wi-Fi interface should work (be detected/enabled).
The second issue you are experiencing is because the root filesystem is kept in read-only mode, by default. To put it in read/write mode, so you can make changes to the system (in this case, configuration changes), you should type this command, prior:
rw
The prompt suffix will then change to
(rw). Then, you can make your changes and they will be persistent.
To put the system back in read-only mode, just type:
ro
The prompt suffix will be back to
(ro).
