Arch Linux User Repository

If anyone is wondering why the source has changed, Dupeguru's website says the maintainer has changed. And so the link https://www.hardcoded.net/dupeguru/ leads us to https://dupeguru.voltaicideas.net/ which in turn has a link to https://github.com/arsenetar/dupeguru/ which is the GitHub repo the sources are downloaded from. So the source change is legitimate.

yeah thank you @batou and fuan_k with your both tipps it works :)

@cybertron: if you already have hsaudiotag3k installed in your python 3.6 site-packages, you can safely copy it over to the 3.7 site-packages, it should work fine.

sudo cp -r /usr/lib/python3.6/site-packages/hsaudiotag3k-1.1.3-py3.6.egg-info /usr/lib/python3.7/site-packages
sudo cp -r /usr/lib/python3.6/site-packages/hsaudiotag /usr/lib/python3.7/site-packages

I have submitted a request to make this package orphan, so that we can fix it ourselves.

1) Make sure your install is fully updated

2) Remove all dupeguru build/source caches

3) Download the PKGBUILD or use your AUR manager of choice and enable it to edit PKGBUILD

4) Add the following section (you can place it before build() for example). This is based upon fuan_k's fix but the src/ is omitted.

prepare(){
  cd "$srcdir"
  sed -i '277 a\\            try:' hscommon/build.py
  sed -i '279s/^/    /' hscommon/build.py
  sed -i '280s/^/    /' hscommon/build.py
  sed -i '281s/^/    /' hscommon/build.py
  sed -i '281a\\            except StopIteration:' hscommon/build.py
  sed -i '282a\\                return' hscommon/build.py
}

It should build fine. Someone should contact this package's maintainer to update it with this fix so all the users can safely update.

hm both tips doesn't work for me it fails by resolving deps hsaudiotag3k the aur versions seems to be available for python 3.6 only?

I haven't had enough time to look at these issues in depth but none of the suggested solutions below worked for me. What worked for me was basically:

$ git clone https://github.com/hsoft/dupeguru.git
#note bellow: make will fail twice because of dependencies. It will build fine on  the 3rd time
$ make
$ make 
$ make
$ make run  #to run the app

unfortunately this will not make a package so you can't install it but it will run if you absolutely need to use dupeguru right away. This is an unmaintained package that's full of issues and temporary fixes. It's a giant mess and it breaks often. Unfortunately, there are no good alternatives.

I came up with a quick fix you can add to the PKGBUILD:

prepare(){
  cd "$srcdir"
  sed -i '277 a\\            try:' src/hscommon/build.py
  sed -i '279s/^/    /' src/hscommon/build.py
  sed -i '280s/^/    /' src/hscommon/build.py
  sed -i '281s/^/    /' src/hscommon/build.py
  sed -i '281a\\            except StopIteration:' src/hscommon/build.py
  sed -i '282a\\                return' src/hscommon/build.py
}

It's basically changing this part of the script with a try/except statement:

    def iter_by_three(it):
        while True:
            version = next(it)
            date = next(it)
            description = next(it)
            yield version, date, description

into the following:

    def iter_by_three(it):
        while True:
            try:
                version = next(it)
                date = next(it)
                description = next(it)
            except StopIteration:
                return
            yield version, date, description

I successfully built afterward and now DupeGuru is working again fine with Python3.7 (so far).

This should be reported upstream, as it's an incompatibility bug with Pyhton 3.7. But the maintainer will have to fix the hsaudiotag3k-1.1.3 dependency issue in the PKGBUILD also... the way it handles it right now doesn't seem very reliable as it fetches from PyPi instead of the AUR?

Ok, thanks. Any idea how to bring this software back to work ? I am desperate, I use it mainly to identify tons of duplicate photos. Or maybe a good linux alternative for this task ? Appreciate assistance :-)

After copying hsaudiotag like so:

cd /usr/lib/python3.6/site-packages
sudo cp -r hsaudiotag3k-1.1.3-py3.6.egg-info ../../python3.7/site-packages
sudo cp -r hsaudiotag ../../python3.7/site-packages

I get another error:

The above exception was the direct cause of the following exception:

Apparently, the StopIteration exception changed in pyhton 3.7: https://www.python.org/dev/peps/pep-0479/

@atescula: this is also related to python having been upgraded from 3.6 to 3.7.
