pdftk fails to exec

[notklaatu]

On Fedora 28, I've installed both hello as a test and pdftk. The first executes successfully, the latter fails.

$ head -n 2 /etc/os-release
NAME=Fedora
VERSION="28 (Twenty Eight)"
$ sudo dnf install -y snapd
[ ... ]
$ sudo systemctl start snapd
$ sudo snap install hello
[ ... ]
$ hello
bash: hello: command not found
$ /var/lib/snapd/snap/hello/20/bin/hello
Hello, World!
$ sudo snap install pdftk
[ ... ] 
$ /var/lib/snapd/snap/pdftk/9/usr/bin/pdftk 
bash: /var/lib/snapd/snap/pdftk/9/usr/bin/pdftk: No such file or directory
$ sudo chmod +x /var/lib/snapd/snap/pdftk/9/usr/bin/pdftk 
Error blah blah: Read-only file system

This is my first experience with snap, so I may be overlooking a step, but given that hello works, I'm assuming pdftk ought to work in the same way, even if I do have to add /var/lib/snapd/snap/ to my PATH. But maybe there's some other path I need to add?

Snap programs should be executed out of /snap/bin . I'm not sure how that would get added to your path on fedora. Does it work if you add that to PATH and use it there?

There is no /snap directory on my system, after having installed with the steps shown above. Maybe this is a larger bug with the snap install, or the snap RPM.

Cool, it seems to be working now.

Following your lead, I did this:

$ sudo ln -s /var/lib/snapd/snap /snap

And now I can execute by providing the full path to the executable:

$ /snap/pdftk/9/usr/bin/pdftk --version

So I'm closing this issue as resolved. Now to look into who owns the snap RPM so I can report the install bug.

Thanks for the snap package! pdftk isn't supported on Fedora any more, apparently, so this snap package is going to make my life a lot easier. Cheers!
