[Olivier Gayot (ogayot)]

Hello and thank you for your bug report,

The logs show that the partition nvme0n1p5 was already mounted. Do you remember mounting the partition yourself (possibly using the file explorer) or did it get mounted automatically?

Thank you,
Olivier

[handsome_feng (feng-kylin)]

Hi, ogayot, It mounted automatically by peony, and we have removed this feature in the new version.
