Bug ID: 453897
Summary: When mounting an encrypted drive with veracrypt,
udisks2 competes with ntfs-3g for the mount
opportunity
Product: frameworks-kdbusaddons
Version: 5.94.0
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
STEPS TO REPRODUCE
1. Open veracrypt
2. Mount an encrypted drive
3. udisks2 competes with ntfs-3g for the mount opportunity
OBSERVED RESULT
udisks2 sometimes fails to pop up the authentication box because the following
error occurs.
```log
Operator of unix-session:2 FAILED to authenticate to gain authorization for
action org.freedesktop.udisks2.filesystem-mount-system for
system-bus-name::1.20 [/usr/bin/kded5] (owned by unix-user:username)
```
The following result will appear when udisks2 successfully obtains permissions.
```log
