分类：System 标签：Fedora

Fedora 29 Beta 早就发布了，前两天也已经 Final Freeze 如果不跳票的话，这个月就发布了，不等了：

https://fedoraproject.org/wiki/DNF_system_upgrade

# dnf install dnf-plugin-system-upgrade
Package python3-dnf-plugin-system-upgrade-2.0.5-3.fc28.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!

导入 Fedora 29 的 GPG KEY 校验安装包：

# rpm -qf /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-29-primary
fedora-gpg-keys-28-5.noarch

# rpm -q gpg-pubkey --qf '%{NAME}-%{VERSION}-%{RELEASE}\t%{SUMMARY}\n'
gpg-pubkey-f5282ee4-58ac92a3    gpg(Fedora 27 (27) <fedora-27@fedoraproject.org>)
gpg-pubkey-9db62fb1-59920156    gpg(Fedora 28 (28) <fedora-28@fedoraproject.org>)

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-29-primary

# rpm -q gpg-pubkey --qf '%{NAME}-%{VERSION}-%{RELEASE}\t%{SUMMARY}\n'
gpg-pubkey-f5282ee4-58ac92a3    gpg(Fedora 27 (27) <fedora-27@fedoraproject.org>)
gpg-pubkey-9db62fb1-59920156    gpg(Fedora 28 (28) <fedora-28@fedoraproject.org>)
gpg-pubkey-429476b4-5a886537    gpg(Fedora 29 (29) <fedora-29@fedoraproject.org>)

更新 /etc/dnf/dnf.conf 忽略 weak 依赖、避免引入 i686 软件包：

# echo -e 'install_weak_deps=False\nexclude=*.i686\n# tsflags=nodocs' >> /etc/dnf/dnf.conf

# cat /etc/dnf/dnf.conf
[main]
gpgcheck=1
installonly_limit=2
clean_requirements_on_remove=True
install_weak_deps=False
exclude=*.i686
# tsflags=nodocs

下载更新所需 rpm 包：

# dnf system-upgrade download --refresh --releasever=29 -y
.... ....
Complete!
Download complete! Use 'dnf system-upgrade reboot' to start the upgrade.
To remove cached metadata and transaction use 'dnf system-upgrade clean'
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.

然后执行重启升级更新命令：

# dnf system-upgrade reboot

饭毕 🍚 回来后就升级好了，最后清理升级前下载的安装包、无用的软件包：

# dnf system-upgrade clean
# dnf clean packages
# dnf autoremove
