This removes some of the wrong, absolute paths pointing to the build location of the AppImage by using a different shebang and some environment variables, set by the linuxdeploy-plugin-conda-hook at the AppImage start. Fixes linuxdeploy#12, fixes linuxdeploy#25 and fixes linuxdeploy#32

I've added an additional replacement for 32bit conda installations. |

There was a problem hiding this comment.
This will break calling any sorts of external tools, because they'll then also have to use all tools contained in the AppDir. Can you think of a different solution perhaps? The use of environment variables like PATH and LD_LIBRARY_PATH is actually an antipattern and has to be done with great care.
To limit the effects, one possible solution would be to create a separate bin dir somewhere in the AppDir that only points to the bundled Python binary/binaries, but none of the other stuff in AppDir/usr/bin. But that's also a hack. I think you could even further limit the effects by generating some sort of unique name for the symlink to the main binary. Then, you can safely use /usr/bin/env linuxdeploy-plugin-conda-python or something like that with bundled tools.
Of course, bundled scripts that just point to /usr/bin/env python would still fail to run. But I'm not sure that issue can be fixed.

Fixes #12, Fixes #25 and Fixes #32
I left out some of the scripts, like:
AppDir/usr/conda/shell/condabin/conda-hook.ps1: No need for PowershellAppDir/usr/conda/conda-meta/*.json: dunno...AppDir/usr/conda/lib/*/*.sh: Some config scripts, not needed I suppose?AppDir/usr/conda/lib/pkgconfig/*.pc: pkg-config files, not needed and no idea how to fix them.AppDir/usr/conda/lib/python3.8/*/*.py: dunno...I only have a base install of conda with no extra packages, so probably not all possible files are covered.
Also some of the regex could be a little bit more sophisticated...
