Fedora

Installation

Installation of Fedora via ISO

I recommend to install Fefora via a netinst based ISO rather than from a full ISO. Indeed, there seems to be a bug while updating the system with the 2nd method.

Repositories

It is recommended to install the 2 following RPM Fusion repositories:

Free RPM Fusion:

$ su -lc 'dnf install --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm' 

Non Free RPM Fusion:

$ su -lc 'dnf install --nogpgcheck http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm' 

Flash & Java

Flash

To install Adobe proprietary Flash in Firefox:

$ sudo dnf install http://linuxdownload.adobe.com/adobe-release/adobe-release-x86_64-1.0-1.noarch.rpm
$ sudo dnf install flash-plugin

Java

Java (both 32bit and 64bit can be installed via RPM) or manually.

To install from RPM (downloaded from Java site):

$ sudo dnf install jre-8u101-linux-x64.rpm

It installs Java in /usr/java/jre1.8.0_101/

RSSOwl

If you prefer RSSOwl over liferea, first install RSSOwl to /opt/rssowl/. If you have the following error:

RSSOwl was unable to create a browser for reading news.
Please refer to the FAQ for further help.

Do as follows:

$ cd /opt/rssowl/xulrunner/
$ chmod 755 $(file * | grep executable | sed 's/:.*//')
$ ./xulrunner --register-user
./xulrunner-bin: error while loading shared libraries: libhunspell-1.2.so.0: cannot open shared object file: No such file or directory

Identify where libhunspell related *.so files are located:

$ locate libhunspell
/usr/lib64/libhunspell-1.3.so.0
/usr/lib64/libhunspell-1.3.so.0.0.0

And create a symbolic link:

$ sudo ln -s /usr/lib64/libhunspell-1.3.so.0 /usr/lib64/libhunspell-1.2.so.0

Now, you should be able to start RSSOwl as follows:

$ cd /opt/rssowl/
$ ./RSSOwl

VMWare

Tricks

Disable ipv6

• Remove any reference to IPv6 in /etc/hosts
• Disable IPv6 in Network Manager (tab IPv6 Settings). Set method to Ignore.

• Add the following lines to /etc/sysctl.conf:

net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1
net.ipv6.conf.enp0s25.disable_ipv6=1
net.ipv6.conf.wlp3s0.disable_ipv6=1

• Apply changes:

$ sudo sysctl -p
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.enp0s25.disable_ipv6 = 1
net.ipv6.conf.wlp3s0.disable_ipv6 = 1

Disable SELinux

$ sudo sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config

python-pip errors

g++ error:/usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory

fix this with:

$ sudo dnf install redhat-rpm-config

Change gnome-boxes default storage path

$ rm -f ~/.local/share/gnome-boxes
$ ln -s /data/virtualmachines/gnome-boxes ~/.local/share/gnome-boxes

Synology drive

Since Synology does not make Fedora packages anymore for Synology Drive, you'll need to make the package yourself using Alien (to convert *.deb to *.rmp).

Alien (prerequisite)

• Install Alien:

$ sudo dnf install alien

• Now you'll need to patch Alien because it does not handle dependencies correctly. To do that, download the patch:

$ cd /tmp/
$ wget https://sourceforge.net/p/alien-pkg-convert/tickets/_discuss/thread/34cd1f59/6647/attachment/alien-8.95-rpm-fix.tar.xz
$ tar xJf alien-8.95-rpm-fix.tar.xz
$ sudo mv alien-8.95/Alien/Package/Rpm.pm /usr/share/perl5/vendor_perl/Alien/Package/Rpm.pm

Installation

• Go to the download center and get the *.deb file (e.g. synology-drive-client-11050.x86_64.deb)
• Convert the DEB package to RPM using the following command:

$ sudo alien --to-rpm -vv synology-drive-client-11050.x86_64.deb

• Now, you should be ready to install:

$ sudo rpm -ivh synology-drive-6.0.0-11051.x86_64.rpm --nodeps
$ sudo ln -s /usr/lib/nautilus/extensions-3.0/libnautilus-drive-extension.so /usr/lib64/nautilus/extensions-3.0/
