Re: Buster WiFi Failure

Please disregard this topic (and delete, if possible). The problem is totally of my making (due to the way I boot Raspbian) and has been resolved.

I got a reply from the mirror admin that there was a configuration issue on the server, it should be fixed now (certainly looks much better from here), so I have reenabled it's mirror redirection entry.

Re: Buster upgrade fails

I just tested that mirror from here, for me it seemed to be working but very slowly. I have disabled it's entry in the mirror redirection system for now, so if you try again you should be directed to a different mirror. That appears to have fixed the problem (it was very reproducible here). Thanks ...

That message is normal and should be ignored. Simply reboot and the filesystem will be expanded (be patient as the expansion process involves an extra reboot that is automatically initiated).

Add me to the list of those experiencing the problem. Reverting to the earlier firmware + kernel appears to be a work-around for the moment:

Re: Cannot resize Raspbian Stretch lite images with Parted

My guess is there isn't 5.6 GB of space left on the destination SD card or it is formatted vfat which can't create a file larger than 2 GB.

Re: Running Raspbian on USB Devices : Made Easy

I suspect the problem is your system is trying to auto-mount the device as soon as you plug it and and exfat isn't supported. The device doesn't need to be (and shouldn't be) mounted prior to running usb-boot. usb-boot will present you with a list of /dev/sdX devices it finds and ask you to select t...

The USB device need not be formatted. The usb-boot script will partition and format the USB device for you.

Re: Running Raspbian on USB Devices : Made Easy

One thing I had to correct manually is that the /boot mount entry remained as referencing the mmcblk1 device in /etc/fstab. Is the script supposed to modify that? It's best that the /boot mount entry in /etc/fstab references /dev/mmcblk0p1. That's where booting is actually originating from and thin...
