At the command line, when you type the following commands, what happens?

which python
which python3
which pip
which pip3

odroid@odroid:~$ which python
/usr/bin/python
odroid@odroid:~$ which python3
/usr/bin/python3
odroid@odroid:~$ which pip
/usr/local/bin/pip
odroid@odroid:~$ which pip3
/usr/local/bin/pip3

Please try making your path in the "Python Exec Folder" /usr/local/bin/ instead of /usr/bin/ and see if that helps.

"Python and Pip both need to be installed in your selected python exec folder in order to run indiweb. Please either install these or change your exec folder to one that includes them."

ok right. I did not think that python and pip would be in different directories. they are not on my systems. Let me see what I can do.

Ok I just updated it to be more flexible on the python and pip paths and to tell you when it doesn't work and why. Did you install via the nightly ppa or did you download from git?

I used the nightly ppa, I'll try git now, to check it out.

Thank you. If you find that it works better with this change, I can send it to the ppa.

After some "fun" installing qt and kdeveloper I think I susccessfully compiled from git. Is this the expected version?

Python and indi-web still says incomplete. When clicking on the Install button
Using either the dfault or non-default python directories generate the

Yes, I haven't updated the version number yet due to the fact that I haven't confirmed yet that it works on your system. But are you running a version that you just built? I am seeing this line:
"2019-06-25T17:41:25: Build: 2019-06-24T19:14:50Z"

Which makes me think you are running the same one you ran before that you got from the nightly build. I purposefully added that line so that we could detect not only which "version" we are running but also when it was built to differentiate between versions with the same number that were built from git at different times etc.

oh also you should change your python exec directory back to /usr/bin instead of /usr/local/bin. That was just a test. It really should be the /usr/bin on your system

Just a note: for mine the build line looks like this:

2019-06-25T14:30:54: Welcome to INDI Web Manager App 0.7
2019-06-25T14:30:54: Build: 2019-06-25T18:25:09Z

The reason the times are different is because of the difference between my time zone and UTC.
