Public bug reported: Briefly: The ubuntu 20.04 installer writes things to disk before the "security prompt" is issued, and without notifying the user, causing massive data loss.
To reproduce: - During installation select one volume as "physical volume for encryption" (One that already is a LUKS volume. For example one from an identical install made minutes earlier). - press "back" - advance, and select the same volume as physical volume for encryptiona gain - A popup will appear (which did not appear the first time) "an error occurred while configuring encrypted volumes - the configuration has been aborted" - Cancel installation - Realize that changes were written to disk, and the original LUKS volume is now inacessible, and all data is lost, even though you never pressed "continue" and never agreed to write any changes to disk I first posted this here, but it is clearly reproducible https://askubuntu.com/questions/1304307/luks-encrypted-disk-gives-error-wrong-fs-type-bad-option-bad-superblock-on ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1909821 Title: During installation error "An error occurred while configuring encrypted" causes data loss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1909821/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
