NAME

6       dnf-system-upgrade - DNF system-upgrade Plugin
7

DESCRIPTION

9       DNF  system-upgrades  plugin  provides  three commands: system-upgrade,
10       offline-upgrade, and offline-distrosync.  Only  system-upgrade  command
11       requires increase of distribution major version (--releasever) compared
12       to installed version.
13
14       dnf system-upgrade can be used to upgrade a Fedora system to a new  ma‐
15       jor  release.  It  replaces fedup (the old Fedora Upgrade tool). Before
16       you proceed ensure that your system is fully  upgraded  (dnf  --refresh
17       upgrade).
18
19       The  system-upgrade command also performes additional actions necessary
20       for the upgrade of the system, for example an upgrade of groups and en‐
21       vironments.

SUBCOMMANDS

55       download
56              Downloads everything needed to upgrade to a new major release.
57
58       reboot Prepares the system to perform the upgrade, and reboots to start
59              the upgrade.  This can only be used after the  download  command
60              completes successfully.
61
62       clean  Remove previously-downloaded data. This happens automatically at
63              the end of a successful upgrade.
64
65       log    Used to see a list of boots during  which  an  upgrade  was  at‐
66              tempted,  or show the logs from an upgrade attempt. The logs for
67              one of the boots can be shown by specifying one of  the  numbers
68              in  the first column. Negative numbers can be used to number the
69              boots from last to first. For example, log  --number=-1  can  be
70              used to see the logs for the last upgrade attempt.
71

OPTIONS

73       --releasever=VERSION
74              REQUIRED. The version to upgrade to. Sets $releasever in all en‐
75              abled repos. Usually a number, or rawhide.
76
77       --downloaddir=<path>
78              Redirect download of packages to provided  <path>.  By  default,
79              packages  are downloaded into (per repository created) subdirec‐
80              tories of /var/lib/dnf/system-upgrade.
81
82       --distro-sync
83              Behave like dnf distro-sync: always install  packages  from  the
84              new release, even if they are older than the currently-installed
85              version. This is the default behavior.
86
87       --no-downgrade
88              Behave like dnf update: do not install packages from the new re‐
89              lease  if  they are older than what is currently installed. This
90              is the opposite of --distro-sync. If  both  are  specified,  the
91              last  option  will  be  used. The option cannot be used with the
92              offline-distrosync command.
93
94       --number
95              Applied with log subcommand will show the log specified  by  the
96              number.
97

NOTES

99       dnf system-upgrade reboot does not create a "System Upgrade" boot item.
100       The upgrade will start regardless of which boot item is chosen.
101
102       The DNF_SYSTEM_UPGRADE_NO_REBOOT environment variable can be set  to  a
103       non-empty  value  to  disable the actual reboot performed by system-up‐
104       grade (e.g. for testing purposes).
105
106       Since this is a DNF plugin, options accepted  by  dnf  are  also  valid
107       here, such as --allowerasing.  See dnf(8) for more information.
108
109       The  fedup  command  is not provided, not even as an alias for dnf sys‐
110       tem-upgrade.
111

BUGS

113       Upgrading from install media (e.g. a DVD or .iso  file)  currently  re‐
114       quires  the  user to manually set up a DNF repo and fstab entry for the
115       media.
116

REPORTING BUGS

130          https://bugzilla.redhat.com/
131
132       For more info on filing bugs, see the Fedora Project wiki:
133          https://fedoraproject.org/wiki/How_to_file_a_bug_report

135          https://fedoraproject.org/wiki/Bugs_and_feature_requests
136
137       Please include /var/log/dnf.log and the output  of  dnf  system-upgrade
138       log --number=-1 (if applicable) in your bug reports.
139
140       Problems  with  dependency solving during download are best reported to
141       the maintainers of the package(s) with the dependency problems.
142
143       Similarly, problems encountered on your system after the  upgrade  com‐
144       pletes  should  be  reported  to the maintainers of the affected compo‐
145       nents. In other words: if (for example) KDE stops working, it's best if
146       you report that to the KDE maintainers.
