AWS Client VPN with SAML for Fedora

gistfile1.txt

The AWS Client VPN for Linux is only provided for Ubuntu as a .deb package. I need it for Fedora. This was tested on Fedora 33.

https://docs.aws.amazon.com/vpn/latest/clientvpn-user/client-vpn-connect-linux.html

Get the vpn client deb package.
```
curl https://d20adtppz83p9s.cloudfront.net/GTK/latest/awsvpnclient_amd64.deb -o awsvpnclient_amd64.deb
```

Install `alien` to convert the deb package to rpm.
```
dnf install alien.noarch -y
```

Convert the deb package to rpm. Some warnings will apper, don't worry.
```
alien -r awsvpnclient_amd64.deb --scripts
```

At this point, if I tried to install the generated rpm package, it failed because some conflicting folders.
```

We need to edit the rpm package and remove these already existing folders from the package using rpmrebuild. Install rpmrebuild.
```
dnf install rpmrebuild.noarch -y
```

And then, edit the rpm package with rpmrebuild removing the previous conflicting folders. https://superuser.com/questions/133317/is-it-possible-to-modify-rebuild-an-rpm-without-the-srpm/133323#133323
```
rpmrebuild -e -p awsvpnclient-1.0.0-2.x86_64.rpm
find the line(s) you wish to change
make changes
save and exit your editor   (Esc:wq! in vi[m], Ctrl-x s in emacs)
rpmrebuild will ask if you want to continue
answer 'yes'
check the last line of the rpmrebuild output to find your package
```

The rpm has been rebuilt and stored in the mentioned folder. Now, install it, it should work now.
```
sudo dnf install /home/user/rpmbuild/RPMS/x86_64/awsvpnclient-1.0.0-2.x86_64.rpm -y

It is not working on fedora 40 :(
nothing provides openssl1.1 needed by awsvpnclient-3.11.0-1.x86_64 from copr:copr.fedorainfracloud.org:vorona:aws-rpm-packages

It works on Fedora 40 / 41 now: https://copr.fedorainfracloud.org/coprs/vorona/aws-rpm-packages/

It works on Fedora 40 / 41 now: https://copr.fedorainfracloud.org/coprs/vorona/aws-rpm-packages/

It'll still fail when trying to connect with this message (even after installing openssl1.1 and openssl1.1-devel): No usable version of libssl was found

There's a new version of the client, 4.1, which supports Ubuntu 22.04 and 24.04 (which I take to mean no longer relies on OpenSSL1.1), but it has yet to be built in the COPR repo.
