I’ve used the shnsplit utility (part of shntool package) to split FLAC files into their individual tracks with a CUE sheet:
shnsplit -o flac -t "%n - %t" -f filename.cue filename.flac
You can of course substitute WAV for FLAC, and there are more options for file name output if you read its manpage.
I went to pray to the dist-upgrade gods today and must have angered them:
Reading package lists... Done
E: Repository 'http://dl.google.com/linux/chrome/deb stable Release' changed its 'Origin' value from 'Google, Inc.' to 'Google LLC'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
I read the apt-secure manpage; it has many grammatical errors but absolutely no information about how to explicitly accept this change of origin name.
The solution is found in the apt-get manpage:
Allow the update command to continue downloading data from a repository which changed its information of the release contained in the repository indicating e.g a new major release. APT will fail at the update command for such repositories until the change is confirmed to ensure the user is prepared for the change. See also apt-secure(8) for details on the concept and configuration.
Specialist options (--allow-releaseinfo-change-field) exist to allow changes only for certain fields like origin, label, codename, suite, version and defaultpin. See also apt_preferences(5). Configuration Item: Acquire::AllowReleaseInfoChange.
TL;DR: the solution is simple:
apt-get --allow-releaseinfo-change-origin update
