[SOLVED]No multilib and problem with mounting partitions

[RIA77]

Hello and thank you for this great community.

EDIT - Just need to install gnome-extra/polkit-gnome

When I was on OpenRC Thunar and multilib profile, there was no any problem with mounting partitions.

After I switched to no multilib, I can't mount partitions with Thunar.
Mounting with terminal is possible, but only with root account.
"Not authorized to perform operation" is Thunar message.
Thank you.

In classic Linux systems, mounting is restricted to the root user, though root can take steps to delegate that permission out to other users. What steps have you taken that you would expect this to work? Is the fstab entry marked to allow users to mount it? Did you install and configure one of the permissions frameworks, such as polkit, that allow the local console user to trigger a mount?
