Bearbeiten von „StuRa Diskussion:Install-Party/Fedora“

== Probleme und Lösungen ==

Treiber fehlen (nach dem versehentlichen Löschen durch <code>dnf</code> mit <code> --allowerasing</code>)
: <code>dnf install mesa-dri-drivers</code>

== wayland oder xorg ==

: <code>echo $XDG_SESSION_TYPE</code>
<pre>
wayland
</pre>

== Verwaltung von Partionen ==

: <code>dnf search blivet-gui</code>
: <code>dnf install -y blivet-gui</code>

== Fedora Silverblue ==

==== Suchen von Paketen ====

<code>rpm-ostree</code> bietet keine Suche für Pakete.

Erstellen von einem allgemeinen Container, falls noch keiner erstellt ist
: <code>toolbox -y create</code>
<pre>
Created container: fedora-toolbox-33
Enter with: toolbox enter
</pre>

Aulisten aller (nun verfügbaren) Abbilder für Container
: <code>toolbox list -i</code>
<pre>
IMAGE ID      IMAGE NAME                                        CREATED
92d6fdd7ebda  registry.fedoraproject.org/f33/fedora-toolbox:33  12 days ago
</pre>
Aulisten aller (nun verfügbaren) Container
: <code>toolbox list -c</code>
<pre>
CONTAINER ID  CONTAINER NAME     CREATED        STATUS      IMAGE NAME
1234567890ab  fedora-toolbox-33  5 minutes ago  configured  registry.fedoraproject.org/f33/fedora-toolbox:33
</pre>

Suchen von einem Paket (beispielsweise dem Paket ''ddate'') mit dem standardmäßigen Programm zur Verwaltung von Paketen <code>dnf</code> von außerhalb vom Container im Container
: <code>toolbox run dnf search ddate</code>
<pre></pre>
<pre>
ddate.x86_64 : Convert Gregorian dates to Discordian dates
</pre>

Entfernen vom allgemeinen Container, falls er nicht mehr gebraucht wird
: <code>toolbox rm fedora-toolbox-33</code>
Entfernen vom Abbild für einen allgemeinen Container, falls es nicht mehr gebraucht wird
: <code>toolbox rmi registry.fedoraproject.org/f33/fedora-toolbox:33</code>

==== Experiment KDE (Wayland) Silverblue ====
