Root authentication added

[abhay44]

@probonopd added root authentication for appimageupdategui. Password will be asked when you run the executable as mentioned in the build.sh and I added README.md.So,it will be easy for users to understand how to build and execute.

Thanks @abhay44 very good progess. However please consider that we cannot write to /usr/share/polkit-1/actions. AppImages are supposed to be self-contained, and must not install things into the system. Do you still see a way to make this work?

[abhay44]

As we are running pkexec and without com.appimageupdate.policy we can't run a graphical interface running on.We have to move the com.appimageupdate.policy to /usr/share/polkit-1/actions inorder to do so.Do you have any other ideas?

[probonopd]

Normal users can't write to /usr so we need to ask the PolicyKit people what to do here. The Etcher AppImage seems to be able to become root without such trickery?

[abhay44]

@probonopd I added authentication as you said. No copying of files to /usr/share/polkit-1/actions. I did something like this.Password will be asked when you open the appimageupdategui. Please see the image in the link.But in popup /bin/echo will be there instead of appimageupdategui (this is the trickiest part of code). I am trying to fix this as of now. Is it ok to keep /bin/echo? I will update the PR on your further suggestions.

Turns out we don't build appimageupdategui yet on Travis CI. I wonder whether we should do a separate GitHub project for it, or build it in the zsync-curl project (another ingredient for the same AppImageUpdate.AppImage).

[abhay44]

So, what's the final verdict?

[probonopd]

I have some more work to do so that this builds on Travis CI. Still thinking about different options. Probably I will put all things AppImageUpdate into its own repository, so that builds of AppImageKit won't take even longer than they already do.

[abhay44]

@probonopd any update? Travis CI build is passed I think.

[probonopd]

Travis CI is actually not building this code yet, which is my fault. I still need to set up a proper repository for AppImageUpdate and set up a Travis CI build job for it.

[probonopd]

Please check AppImageCommunity/AppImageUpdate#1 @abhay44. I opened a new GitHub project especially for AppImageUpdate, which correctly builds the AppImage on each git push.

AppImageUpdate has been moved to https://github.com/probonopd/AppImageUpdate.
