<div id="outline-container-orgffc515a" class="outline-2">
<h2 id="orgffc515a">Update</h2>
<div class="outline-text-2" id="text-orgffc515a">
</div>
<div id="outline-container-org1dbb612" class="outline-3">
<h3 id="org1dbb612">System packages</h3>
<div class="outline-text-3" id="text-org1dbb612">
<p>
To check packages to update:
</p>
<div class="org-src-container">
<pre class="src src-bash">paru -Qu
</pre>
</div>
<p>
And then to perform the update:
</p>
<div class="org-src-container">
<pre class="src src-bash">paru
</pre>
</div>
</div>
</div>
<div id="outline-container-orge4759bc" class="outline-3">
<h3 id="orge4759bc">NPM</h3>
<div class="outline-text-3" id="text-orge4759bc">
<p>
First update <code>npm</code> itself
</p>
<div class="org-src-container">
<pre class="src src-bash"><span class="org-type">sudo</span> npm install npm@latest -g
</pre>
</div>
<p>
Then, we can list outdated packages:
</p>
<div class="org-src-container">
<pre class="src src-bash">npm outdated -g --depth=<span class="org-highlight-numbers-number">0</span>
</pre>
</div>
<p>
And finally perform the update:
</p>
<div class="org-src-container">
<pre class="src src-bash"><span class="org-type">sudo</span> npm update -g
</pre>
</div>
</div>
</div>
<div id="outline-container-org359ad9e" class="outline-3">
<h3 id="org359ad9e">PIP</h3>
<div class="outline-text-3" id="text-org359ad9e">
<p>
First upgrade <code>pip</code> itself:
</p>
<div class="org-src-container">
<pre class="src src-bash">/usr/bin/python3 -m pip install --upgrade pip
</pre>
</div>
<p>
Then list outdated packages:
</p>
<div class="org-src-container">
<pre class="src src-bash">pip3 list --outdated
</pre>
</div>
<p>
And update everything with:
</p>
<div class="org-src-container">
<pre class="src src-bash">pip3 list --outdated --format=freeze | <span class="org-type">grep</span> -v <span class="org-string">'^\-e'</span> | cut -d = -f <span class="org-highlight-numbers-number">1</span> | xargs -n1 pip3 install -U
</pre>
</div>
</div>
</div>
<div id="outline-container-org4a73361" class="outline-3">
<h3 id="org4a73361">Emacs and Vim</h3>
<div class="outline-text-3" id="text-org4a73361">
<p>
Update Doom emacs with:
</p>
<div class="org-src-container">
<pre class="src src-bash">doom up
</pre>
</div>
<p>
And Vim packages with:
</p>
<div class="org-src-container">
<pre class="src src-bash">nvim -c PlugUpgrade -c PlugUpdate
</pre>
</div>
</div>
</div>
</div>
<div id="outline-container-org91cdfc6" class="outline-2">
<h2 id="org91cdfc6">Check problems in the system</h2>
<div class="outline-text-2" id="text-org91cdfc6">
<p>
First check for failed services:
</p>
<div class="org-src-container">
<pre class="src src-bash">systemctl --failed
</pre>
</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
</pre>
</div>
</div>
</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):
</p>
<div class="org-src-container">
<pre class="src src-bash">ancient-packages
</pre>
</div>
</div>
