To check packages to update:

And then to perform the update:

</p>
|

<div class="org-src-container">

First check for failed services:

<div class="org-src-container">
|

<pre class="src src-bash">systemctl --failed

</div>
|
||
|

|

<p>
|

Same for user services:

</p>
|
||
|
|
<div class="org-src-container">
|
||
|
|
<pre class="src src-bash">systemctl --user --failed

</pre>
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Look for errors in the logs:
|
||
|
|
</p>
|
||
|
|
<div class="org-src-container">
|
||
|
|
<pre class="src src-bash"><span class="org-type">sudo</span> journalctl -p <span class="org-highlight-numbers-number">3</span> -b

</div>

|
|
|

<div id="outline-container-org51b97e6" class="outline-2">
|
||

|
<h2 id="org51b97e6">Check orphan and dropped packages</h2>
|
||
|
|
<div class="outline-text-2" id="text-org51b97e6">
|
||
|
|
<p>
|

Run the following to list all orphan packages:
|
||
|
|
</p>
|
||
|
|
<div class="org-src-container">
|
||
|
|
<pre class="src src-bash">pacman -Qtdq | fzf --preview <span class="org-string">'pacman -Qil {}'</span> --layout=reverse --bind <span class="org-string">'enter:execute(pacman -Qil {} | </span><span class="org-type"><span class="org-string">less</span></span><span class="org-string">)'</span>

</pre>
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Then, either remove the unused packages or set the package to “explicitly installed” with:
|
||
|
|
</p>
|
||
|
|
<div class="org-src-container">
|
||
|
|
<pre class="src src-bash"><span class="org-type">sudo</span> pacman -D --asexplicit package_name
|

</pre>
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Use the <code>ancient-packages</code> (<a href="https://aur.archlinux.org/packages/ancient-packages/">link</a>) command to list dropped packages (packages may longer in the remote repositories, but still on the local system):
|
||
|
|

|
<div class="org-src-container">
|

<pre class="src src-bash">ancient-packages
