Public bug reported: Xubuntu 20.04.2 ubiquity 20.04.15.10 partman-crypto
Lost an lvm PV because of this. Steps to reproduce: 1. Create encrypted partition with cryptsetup luksFormat 2. Check crypt partition UUID with cryptsetup luksUUID 3. Close crypt volume with cryptsetup luksClose if necessary. Launch ubiquity installer. … 4. no updates 5. Installation type: Something else 6. Select an existing Luks partition and change to "physical volume for encryption". 7. "Edit partition" dialog options for "Format the partition" and "Overwrite empty disk space" are unchecked. Enter key and confirm. 8. Long pause. Crypt volume appears on main window. 9. Check crypt partition UUID again. It has changed due to an unrequested luksFormat. 10. Syslog shows: xubuntu partman-crypto: WARNING: Device /dev/sda1 already contains a 'crypto_LUKS' superblock signature. 11. Repeat with the crypt volume open to block writes. Error dialog after step #7 reports "Configuration of encrypted volumes failed" "An error occurred while configuring encrypted volumes. The configuration has been aborted". 12. Syslog shows: xubuntu partman-crypto: Device /dev/sda1 is in use. Can not proceed with format operation. xubuntu partman-crypto: WARNING: Device /dev/sda1 already contains a 'crypto_LUKS' superblock signature. Tried ubiquity --debug but didn't find anything pertaining to the problem in the other logs. Not sure if the problem is with ubiquity, partman-crypto, or both. It needs a "cryptsetup isLuks" check somewhere along with some warnings.
