+title: How to Fix Hetzner ARM64 VPS Package Updates on Ubuntu 24.04

+
+Real quick one from me on updating a Hetzner VPS with something like
+`apt update`. I noticed some weird behaviour today when I wanted to
+install `sqlite3` on my Hetzner box. I was greeted with the following
+message:
+
+```bash
+sudo apt install sqlite3
+Reading package lists... Done
+Building dependency tree... Done
+Reading state information... Done
+Suggested packages:
+  sqlite3-doc
+The following NEW packages will be installed:
+  sqlite3
+0 upgraded, 1 newly installed, 0 to remove and 35 not upgraded.
+Need to get 140 kB of archives.
+After this operation, 587 kB of additional disk space will be used.
+Err:1 https://mirror.hetzner.com/ubuntu/packages noble/main arm64 sqlite3 arm64 3.45.1-1ubuntu2
+  404  Not Found [IP: 2a01:4ff:ff00::3:3 443]
+E: Failed to fetch https://mirror.hetzner.com/ubuntu/packages/pool/main/s/sqlite3/sqlite3_3.45.1-1ubuntu2_arm64.deb  404  Not Found [IP: 2a01:4ff:ff00::3:3 443]
+E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
+```
+
+So a little searching with Perplexity which surfaced this result from
+[geo.rocks](https://geo.rocks/post/hetzner_arm_update) apparently
+Hetzner are no longer mirroring packages for ARM based systems. I'm
+running Ubuntu 24.04.1 LTS on a Hetzner CAX (ARM64) server.
+
+So, backup the existing `sources.list` file and create a new one.
+
+```bash
+cd /etc/apt
+mv sources.list /root/sources.list.backup
+```
+
+Then open up the new `sources.list.d/ubuntu.sources` file.
+
+```bash
+nano /etc/apt/sources.list.d/ubuntu.sources
+```
+
+Then you get a pretty scary looking file.
+
+```nano
+## Note, this file is written by cloud-init on first boot of an instance
+## modifications made here will not survive a re-bundle.
+##
+## If you wish to make changes you can:
+## a.) add 'apt_preserve_sources_list: true' to /etc/cloud/cloud.cfg
+##     or do the same in user-data
+## b.) add supplemental sources in /etc/apt/sources.list.d
+## c.) make changes to template file
+##      /etc/cloud/templates/sources.list.ubuntu.deb822.tmpl

+## The following settings can be adjusted to configure which packages to use from Ubuntu.
+## Mirror your choices (except for URIs and Suites) in the security section below to
+## ensure timely security updates.
+##
+## Types: Append deb-src to enable the fetching of source package.
+## URIs: A URL to the repository (you may add multiple URLs)
+## Suites: The following additional suites can be configured
+##   <name>-updates   - Major bug fix updates produced after the final release of the
+##                      distribution.
+##   <name>-backports - software from this repository may not have been tested as
+##                      extensively as that contained in the main release, although it includes
+##                      newer versions of some applications which may provide useful features.
+##                      Also, please note that software in backports WILL NOT receive any review
+##                      or updates from the Ubuntu security team.
+## Components: Aside from main, the following components can be added to the list
+##   restricted  - Software that may not be under a free license, or protected by patents.
+##   universe    - Community maintained packages.
+##                 Software from this repository is only maintained and supported by Canonical
+##                 for machines with Ubuntu Pro subscriptions. Without Ubuntu Pro, the Ubuntu
+##                 community provides best-effort security maintenance.
+##   multiverse  - Community maintained of restricted. Software from this repository is
+##                 ENTIRELY UNSUPPORTED by the Ubuntu team, and may not be under a free
+##                 licence. Please satisfy yourself as to your rights to use the software.
+##                 Also, please note that software in multiverse WILL NOT receive any
+##                 review or updates from the Ubuntu security team.

+Types: deb

+## Ubuntu security updates. Aside from URIs and Suites,

+Types: deb
+URIs: https://mirror.hetzner.com/ubuntu/security
+Suites: noble-security
+Components: main universe restricted multiverse

+```
+
+Essentially, that last section needs changing from:
+
+```nano
+Types: deb
+URIs: https://mirror.hetzner.com/ubuntu/packages
+Suites: noble noble-updates noble-backports
+Components: main universe restricted multiverse
+Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
+
+Types: deb
+URIs: https://mirror.hetzner.com/ubuntu/security
+Suites: noble-security
+Components: main universe restricted multiverse
+Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
+```
+
+To:
+
+```nano
+Types: deb
+URIs: https://mirror.hetzner.com/ubuntu-ports/packages
+Suites: noble noble-updates noble-backports
+Components: main universe restricted multiverse
+Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
+
+Types: deb
+URIs: https://mirror.hetzner.com/ubuntu-ports/security
+Suites: noble-security
+Components: main universe restricted multiverse
+Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
+```
+
+Then I can run `sudo apt update` and `sudo apt install sqlite3`
+without any issues.
+
+So, we're good to go.
