I am getting the “ciphertext verification failed” error. After reading up & troubleshooting, I found that I have two keys in the restic repo for some reason. I tried removing each key & testing commands with only the other. One key fails entirely:
bash-5.0# ls keys/
d0e60b21003c312e502cc56c2952f804aef4cd48f43ed2b6752dcd62b2e5288e
bash-5.0# restic -r . snapshots
Fatal: config cannot be loaded: ciphertext verification failed
One key mostly works, but fails with some snapshots:
bash-5.0# ls keys/
4d1f290e2b2437fee62899a03d64d68eb4032522e8d75e8cb72dace1d9d046e8
bash-5.0# restic -r . snapshots

There’s no overlap between the “ciphertext verification failed” list and the successful snapshots list.
My codebase calls the above method with the --json flag & parses it. That’s failing, since it’s prefaced with the “could not load snapshot fc6124b5: ciphertext verification failed” errors. I tried running restic forget for all of the ciphertext issue snapshots, but that outputs: “Ignoring “[hash]”, could not load snapshot: ciphertext verification failed”
Can I safely delete those snapshots? Changing to the other key doesn’t let me delete them. I’d like to simply delete the directories for these snapshots, but I’m not sure that’s safe.
