Installing and uninstalling seemingly not possible

[klettervirus]

I tried to install toltec, but obviously did that before some years ago. On my rm1. Software Version 2.7.0.51
The following happens, when I 1) try to install it and 2) try to remove it:

╺━┓┏━╸┏━┓┏━┓   ┏━╸┏━┓┏━┓╻ ╻╻╺┳╸┏━┓┏━┓

┗━╸┗━╸╹┗╸┗━┛   ┗━┛╹┗╸╹ ╹┗┛ ╹ ╹ ╹ ╹┗━┛
reMarkable: ~/ toltecctl uninstall
-sh: toltecctl: command not found
reMarkable: ~/ wget http://toltec-dev.org/bootstrap
Connecting to toltec-dev.org (5.161.99.157:80)
wget: can't open 'bootstrap': File exists

Can someone please point me to a way to remove any residue from previous installs so I can get a new clean install? Sorry, my Linux knowledge is only tiny, I can use a command line, but have no idea how to get a handle on this one.
Thank for all the effort and support!
