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!

Have you tried removing the existing bootstrap file first? (rm bootstrap)

Yes, that did the trick, thank you! Unfortunately there seems to be another issue (not sure if this is the place to talk about it though). On installing it cannot remove /opt and the script is not installed:

Should I open another issue with this? I looked in the discussion and in "Issues", but it seems like I am the only one with this issue?! I am also not sure if I should put this Problem into the Issues section. Since it might be connected to the first part above, I will leave it here.

Thanks for all the kind help!

It's a bit late, but did you ever resolve this?
