htop won't launch from the menu. Error is "Failed to execute child process 'sakura' (No such file or directory)".
Sakura isn't installed. /etc/alternatives/x-terminal-emulator is linked to /usr/bin/lxterm. I tried linking to /usr/bin/urxvt, but it still won't execute from the menu, although it will start from within a terminal. ~/.local/share/applications is empty. The htop.desktop file in /usr/share/applications/ has for the exec line:
Exec=htop
I take it you are using Villagebox, as Scorpio doesn't show that - don't ask, they share the same base!!  After researching this it seems the only way to fix the problem is to edit the .desktop file htop.  I didn't seem to get quite the right result when reconfiguring update-alternatives.
Su to /usr/share/applications/Htop and edit it thus - "Terminal=true"  to  "Terminal=false"
                                                                                         "Exec=htop"      to   "Exec=xterm -e htop"
Note that the name of the terminal is your choice, but the default is xterm.  Interestingly, before I edited the htop.desktop file, double-clicking on it opened htop in xterm!  Go figure.  Looks like I'll need to retain the edit for remastering.
