Read it at the original source: ## Questions this post answers ### Is it safe to use the Arch User Repository (AUR) after the recent supply chain attack? The AUR remains a valuable resource but requires careful use after attackers took over a number of orphaned packages and inserted malicious code into their package builds, an incident that affected hundreds of packages. Reviewing a package build before installing it, especially unfamiliar ones, and preferring official repositories or Flathub first reduces the risk. _Developers weighing AUR risk against convenience can track community security guidance on daily.dev._ ### How do I set up Flatpak with Flathub on Arch Linux? Install the flatpak package via pacman, then add the Flathub repository with the flatpak remote-add command pointing to the Flathub URL. Optionally install GNOME Software for a graphical interface, since it integrates with Flatpak (but not with pacman) for browsing, installing, and updating Flatpak apps like Steam, Discord, or Spotify. _Anyone comparing Flatpak against native repos on daily.dev can weigh the tradeoffs before choosing a workflow._ ### How do I enable SSD trim support on Arch Linux? Enable and start the fstrim.timer systemd unit with sudo systemctl enable --now fstrim.timer, which schedules a weekly trim operation by default. This tells the SSD which blocks are no longer in use, helping the drive manage storage more efficiently and maintain performance over time. _Developers tuning storage performance on Linux systems can revisit setup checklists like this on daily.dev._ ## Similar posts on daily.dev - [10 tweaks every new Arch Linux install needs](https://daily.dev/posts/10-tweaks-every-new-arch-linux-install-needs-9blcl350f) · All Things Open · 0 upvotes · 0 comments - [I run these 4 commands first on every fresh Linux install](https://daily.dev/posts/i-run-these-4-commands-first-on-every-fresh-linux-install-v6o2vsqik) · XDA Developers · 0 upvotes · 0 comments - [Walking Through a Minimal Arch Linux Set Up with archinstall — Nick Janetakis](https://daily.dev/posts/walking-through-a-minimal-arch-linux-set-up-with-archinstall-nick-janetakis-9r9iqu5ad) · Nick Janetakis · 2 upvotes · 0 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#sysadmin](https://daily.dev/tags/sysadmin) [View this post on daily.dev](https://daily.dev/posts/10-important-tweaks-you-should-make-after-installing-arch-ucizir7kg) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"10 Important Tweaks You Should Make After Installing Arch","url":"https://daily.dev/posts/10-important-tweaks-you-should-make-after-installing-arch-ucizir7kg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/10-important-tweaks-you-should-make-after-installing-arch-ucizir7kg"},"datePublished":"2026-07-30T15:03:09.504Z","dateModified":"2026-09-14T06:39:13.528Z","description":"A walkthrough of 10 post-installation steps for Arch Linux, covering: optimizing the mirror list with Reflector, learning Pacman basics (install, remove,...","image":"https://i.ytimg.com/vi/MLAa2Sf_3QU/sddefault.jpg","thumbnailUrl":"https://i.ytimg.com/vi/MLAa2Sf_3QU/sddefault.jpg","isAccessibleForFree":true,"articleSection":"Learn Linux TV","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Learn Linux TV","logo":"https://media.daily.dev/image/upload/s--9jdbhQUw--/f_auto/v1743317312/logos/learnlinuxtv","url":"https://daily.dev/sources/learnlinuxtv"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/10-important-tweaks-you-should-make-after-installing-arch-ucizir7kg","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"linux,sysadmin","timeRequired":"PT34M","video":{"@type":"VideoObject","name":"10 Important Tweaks You Should Make After Installing Arch","description":"A walkthrough of 10 post-installation steps for Arch Linux, covering: optimizing the mirror list with Reflector, learning Pacman basics (install, remove,...","thumbnailUrl":"https://i.ytimg.com/vi/MLAa2Sf_3QU/sddefault.jpg","uploadDate":"2026-07-30T15:03:09.504Z","duration":"PT34M","url":"https://api.daily.dev/r/uCiZir7kG","embedUrl":"https://www.youtube.com/embed/MLAa2Sf_3QU"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Learn Linux TV","item":"https://daily.dev/sources/learnlinuxtv"},{"@type":"ListItem","position":3,"name":"10 Important Tweaks You Should Make After Installing Arch"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/10-important-tweaks-you-should-make-after-installing-arch-ucizir7kg#faq","mainEntity":[{"@type":"Question","name":"Is it safe to use the Arch User Repository (AUR) after the recent supply chain attack?","acceptedAnswer":{"@type":"Answer","text":"The AUR remains a valuable resource but requires careful use after attackers took over a number of orphaned packages and inserted malicious code into their package builds, an incident that affected hundreds of packages.
