Some shell programs are missing in 24.04-1

[ikoz]

@Charly The first time you open the shell (through ssh) it says "the system has been minimized", which was done to reduce the rootfs size. You can use these programs under Libertine or run a local build of them (preferably statically linked).

@ikoz Many of the regular shell-related things are also available as snaps.

@RJDan
Thanks! How do I install snap programs?

Greetings Charly

@Charly
I think you first need to install snapz0r app from open store.
https://open-store.io/app/snapz0r.fredldotme

But not sure if only thing to do and if compatible with 24.04.

Edit : seem not compatible with 24.04 reading app description and comments, so wait for someone who know better than me

@Charly On Noble, snaps is preinstalled so you just run snap commands like snap install <app name>

You can also try Crackle which uses Nix.

@kugiigi

Thanks, that's interesting.
Would it make sense to install shell programs like fdisk or rsync via snap?

Greetings Charly

[ikoz]

@Charly Snap doesn't make sense for these small standalone utilites. Also fdisk doesn't exist as snap and rsync packages are only some outdated third party programs, which I would never install.

[Bolly]

@Charly Were you able to resolve the Rsync issue?

I'd say that if you download the arm package from an Ubuntu ports repo, such as:

wget http://mirror.kumi.systems/ubuntu-ports/pool/main/r/rsync/rsync_3.2.7-0ubuntu0.22.04.4_arm64.deb

if you don't trust this particular mirror (most of them are in China anyway), here is a script that can give you (more or less) all mirrors:

#!/bin/bash

# URL of the Launchpad mirror list
MIRROR_LIST=https://launchpad.net/ubuntu/+archivemirrors

# Set to the architecture you're looking for (e.g., amd64, i386, arm64, armhf, armel, powerpc, ...).
# See https://wiki.ubuntu.com/UbuntuDevelopment/PackageArchive#Architectures
ARCH=$1
# Set to the Ubuntu distribution you need (e.g., precise, saucy, trusty, ...)
# See https://wiki.ubuntu.com/DevelopmentCodeNames
DIST=$2
# Set to the repository you're looking for (main, restricted, universe, multiverse)
# See https://help.ubuntu.com/community/Repositories/Ubuntu
REPO=$3

# First, we retrieve the Launchpad mirror list, and massage it to obtain a newline-separated list of HTTP mirrors
for url in $(curl -s $MIRROR_LIST | grep -Po 'http://.*(?=">http</a>)'); do
  # If you like some output while the script is running (feel free to comment out the following line)
  echo "Processing $url..."
  # retrieve the header for the URL $url/dists/$DIST/$REPO/binary-$ARCH/; check if status code is of the form 2.. or 3..
  curl -o /dev/null -L -s -w '%{response_code}' -I $url/dists/$DIST/$REPO/binary-$ARCH | grep -q "200"
  # if successful, output the URL
  [ $? -eq "0" ] && echo "FOUND: $url" && curl -o /dev/null -L -s -w '%{response_code}' -I $url/dists/$DIST/$REPO/binary-$ARCH 

done

call it with

sh find-mirrors.sh arm64 noble main

disclaimer: did not write it, found it on github and adapted it (but there are still some problems badly configurated sites are getting 'found' incorrectly)

then once you picked a correct mirror, run

wget http://mirror.kumi.systems/ubuntu-ports/pool/main/r/rsync/rsync_3.2.7-0ubuntu0.22.04.4_arm64.deb

mkdir mydir
dpkg  --extract rsync_3.2.7-0ubuntu0.22.04.4_arm64.deb mydir

then get the binary from 'mydir/usr/bin', it will just work because all necessary libraries are already present in Ubuntu ports noble.

Yes you have then to update it yourself in case of upgrades by Ubuntu.

Alternatively, you can be an open source hero and package rsync as an AppImage. I don't recommend it unless you appreciate what it takes.

@Bolly

No, I'm just waiting now to see whether my suggestions are taken up.

If necessary, I can use syncthing instead of rsync.

But of course it's a shame if you have a shell but the programs are missing.
