I posted this is a fix but I wasn’t sure because I’d only tried it the once. However, this weekend I went away so turned off the Raspberry Pi. Came back and it wouldn’t boot up again. I’d had a new class 10 SD card delivered (was using 4 previously) so figured I’d start again.
Installed, mounted and tried to play a flac file. I had the annoying pops and clicks that I had last time I installed. So despite some posts suggesting otherwise, I formatted and re-installed, then ran the following code after first boot:
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package binutils is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package ‘binutils’ has no installation cadidate
