Updating to a different release involves first updating the system, and then using the
# yum -y update # dnf system-upgrade download --refresh --releasever=30 # dnf system-upgrade reboot
On Fedora 22 or later, use
dnf-automatic. This is actually the same but newer mechanism as
yum-cron used in CentOS 7 but uses systemd timers rather than cron to initiate the update.
# dnf install dnf-automatic ## Edit /etc/dnf/automatic.conf so that apply_updates is set to 'yes' # systemctl enable --now dnf-automatic-install.timer
To schedule automatic updates to happen only at a specific time or week day, edit the timer.
For example, the following timer only runs updates at the start of each week plus 1 hour and some random amount of time (between 0 and 5 minutes).
# cat /usr/lib/systemd/system/dnf-automatic-install.timer [Unit] Description=dnf-automatic-install timer # See comment in dnf-makecache.service ConditionPathExists=!/run/ostree-booted Wants=network-online.target [Timer] OnCalendar=weekly AccuracySec=1h RandomizedDelaySec=5m [Install] WantedBy=multi-user.target # systemctl list-timers --all | grep dnf-auto Mon 2019-05-20 00:01:12 MDT 1 day 1h left Sat 2019-05-18 22:37:54 MDT 8min ago dnf-automatic-install.timer dnf-automatic-install.service
Disabling Nouveau Drivers
As mentioned at https://ask.fedoraproject.org/en/question/23982/how-to-disable-nouveau-in-fedora-18/, to disable the nouveau drivers (needed to install the nvidia drivers), you have to modify the initramfs image using dracut.
# dracut --force --omit-drivres nouveau /boot/initramfs-$(uname -r) $(uname -r)
I tried to do the usual modprobe.d to black list nouveau, but it didn't seem to work. I even added nomodeset on to the grub kernel cmdline but that also didn't seem to work...
Grub configuration needs to be updated by running
# grub2-mkconfig -o /boot/grub2/grub.cfg
The main grub configuration file is at
/etc/default/grub. You must remake the configratuion for grub after you edit this file.
Cuda 8.0 on Fedora 26
Cuda 8.0 seems to need GCC 5.3.1. The closest I can find is GCC 5.3.0 at https://ftp.gnu.org/gnu/gcc/gcc-5.3.0/.
You may need to apply this fix: https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=ec1cc0263f156f70693a62cf17b254a0029f4852
Install any missing dependencies. These were missing on the existing Fedora 26 workstations in computer science:
Compile on the system:
# ./configure --prefix=/usr/local/gcc-5.3.0 --disable-multilib # make -j 8
