Debian RPi stuck installing remoteit

Question

On my RPi 4B, I started installing a .deb file for remoteit but it has gotten stuck.  I may have chosen the wrong install file?  I've tried all the methods I could find to unlock it and stop installation but no luck.  dpkg: error: dpkg frontend lock is locked by another process

These didn't move me forward:

sudo dpkg --configure -a

rm /var/lib/apt/lists/lock

lsof /var/lib/dpkg/lock  Results in this message:

lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
      Output information may be incomplete.
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF   NODE NAME
dpkg    21485 root    4uW  REG  179,7        0 654376 /var/lib/dpkg/lock

I tried killing the PID but always get back to the message "Setting up remoteit (4.13.5)

What else can I try?
