Hello, and thank you for this OS.
Have tried with a blank SSD, and with MBR and partition, and it fails when creating the swap, I think it is. A big pop-up pops up, with that it did, but with an error. Using “erase disk”.
Edit: From Github https://github.com/calamares/calamares/issues/1196
Based on your log you are still using 3.2.10 . Well, we updated to 3.2.11 and changed the whole setup of encryption. Please redo your tests and report back if the issue is still given. You may use 18.1-rc5 install medias from Manjaro, which provide the latest CAL already.
Is the stable using Calmares 3.2.11?
