Installation not working on bash 5.1.16 in Debian

[oyedejioyewole]

I tried installing some terminal color schemes from here
The installation worked for my Arch Gnome Shell but for my Debian Gnome Shell it gives me this error

bash: line 944: read: `/apps/gnome-terminal/profiles/default_profile': not a valid identifier
environment: line 684: --get: command not found
environment: line 693: --get: command not found

I am using bash as the shell using to execute this program as shown here

oyedejioyewolemaxwell@oyedejioyewolemaxwell:~$ echo $SHELL
/bin/bash

The same here on Debian unstable. It says that it is installed, but no new profile is seen in the terminal settings. When I try to install second time and choose the same theme, it says that the profile already exists.

Update:
Notices a preinstalled script which is on github but missing on the main website. After installing it, everything worked.

I ran into the same issue but I tried it again after adding a new profile in terminal settings and it worked. Not sure why that is and I haven't got the time to investigate further

not sure why its closed as completed, bug is still happening (also on arch linux). for now it can be fixed by creating a new profile, like mentioned above.
