コマンドを試していますが、systemctl enable multi-user.target次のような結果が表示されます。
The unit files have no installation config (WantedBy=, RequiredBy=, Also=,
Alias= settings in the [Install] section, and DefaultInstance= for template
units). This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
• A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
• A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
• A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
• In case of template units, the unit is meant to be enabled with some
instance name specified.
同じことが起こりました。systemctl enable graphical.target
systemctl disable2つを同時に使ってみましたが、何の効果もありませんでした。
systemctl isolate注：または再起動を使用して起動ターゲットに切り替えることもできますsystemctl set-default。しかし、なぜandsystemctl enable/disableでは動作しないのか知りたいのですが。mult-user.targetgraphical.target
