cannot access encrypted USB drive with Thunar in Whonix 15

[Patrick]

Thunar issues could be related to root / sudo / pkexec.

See this thread / try this workaround:

cannot use pkexec

Could try this workaround. It replaces pkexec with lxsudo. That might fix all applications. sudo cp /usr/bin/pkexec /usr/bin/pkexec.backup sudo rm /usr/bin/pkexec sudo ln -s /usr/bin/lxsudo /usr/bin/pkexec
