Installing .net on RPi

[Nottub]

So in anticipation of some pain ahead I have begun the process of installing .net on my RPi.

I am running Raspbian GNU/Linux 10 (buster), which looking at Marks instructions is not covered by his easy to copy scripts and instead is referenced by a link to; "https://learn.microsoft.com/en-gb/dotne ... ed-install".

1)
I used the 'Scripted Install' method and selected the 'Run Time' Version to install, 'wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh', and the permissions command 'chmod +x ./dotnet-install.sh'

Here is the resulting message:

pi@raspberrypi:~ $ ./dotnet-install.sh --version latest --runtime aspnetcore
dotnet-install: Attempting to download using aka.ms link https://dotnetcli.azureedge.net/dotnet/ ... arm.tar.gz
dotnet-install: Remote file https://dotnetcli.azureedge.net/dotnet/ ... arm.tar.gz size is 40125024 bytes.
dotnet-install: Extracting zip from https://dotnetcli.azureedge.net/dotnet/ ... arm.tar.gz
dotnet-install: Downloaded file size is 40125024 bytes.
dotnet-install: The remote and local file sizes are equal.
dotnet-install: Installed version is 8.0.3
dotnet-install: Adding to current process PATH: `/home/pi/.dotnet`. Note: This change will be visible only when sourcing script.
dotnet-install: Note that the script does not resolve dependencies during installation.
dotnet-install: To check the list of dependencies, go to https://learn.microsoft.com/dotnet/core/install, select your operating system and check the "Dependencies" section.
dotnet-install: Installation finished successfully.


Importantly The last line reads 'Installation finished successfully'.

2)
Next I ran the Dependencies for 'debian (as below)

pi@raspberrypi:~ $ sudo apt install libc6
Reading package lists... Done
Building dependency tree
Reading state information... Done
libc6 is already the newest version (2.28-10+rpt2+rpi1+deb10u2).
The following packages were automatically installed and are no longer required:
libdav1d3 libnunit-cil-dev libnunit-console-runner2.6.3-cil libnunit-core-interfaces2.6.3-cil libnunit-core2.6.3-cil libnunit-framework2.6.3-cil
libnunit-mocks2.6.3-cil libnunit-util2.6.3-cil libpipewire-0.2-1 mono-jay xdg-desktop-portal xdg-desktop-portal-gtk
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

3)
Finally to check the install I ran 'dotnet --version' hoping to see V8 mentioned, alas not to be.

pi@raspberrypi:~ $ dotnet --version
bash: dotnet: command not found
pi@raspberrypi:~ $

Is this Ok or not?
Do I need to restart my Pi for the update?

Thanks
and please be patient with me.

Hi Martyn

Try dotnet --info

This should get 8.0.103 as the version on your RPi

Hi Martyn

Try dotnet --info

This should get 8.0.103 as the version on your RPi

Thanks Andy, tried that and the same response:

“bash: dotnet: command not found”

Thanks for the recommendation.

I'm not familiar with Gnu, but you could try doing the last installation step (4) in my instructions (changing the path as you have installed to the default $HOME/.dotnet folder), these make dotnet "visible" to every login...

Code: Select all

sudo echo 'export PATH=$PATH:/home/pi/.dotnet' | sudo tee /etc/profile.d/dotnet.sh > /dev/null
sudo chmod +x /etc/profile.d/dotnet.sh
sudo ln -s /home/pi/.dotnet/dotnet /usr/bin/dotnet

Hi Martyn

Looking at your install it seems that it is trying to install an old version of dotnet. The method I used was that shown on GitHub and here are my notes for the install. It might help you, certainly the PATH bit that Mark suggested is included for the initial install.

Code: Select all

To update the dotnet installation.

First remove any existing .NET install:

	sudo rm -r /usr/share/dotnet

The GitHub install method installs the latest version, SDKs not needed or installed

	curl -sSL https://dot.net/v1/dotnet-install.sh | bash /dev/stdin --version latest --verbose

To test the install the following will show the version and other information

	dotnet --info

A final test from the terminal @CumulusMX will prove the installation.

	dotnet utils/bin/cumulusutils.dll website



The following only needs to be done once at the initial install

Install the .NET dependencies  for Debian 12 bookworm

	sudo apt-get update
	sudo apt install libc6 libgcc-s1 libgssapi-krb5-2 libicu67 libssl1.1 libstdc++6 zlib1g

Then next do the following

	sudo echo 'export PATH=$PATH:/usr/share/dotnet' | sudo tee /etc/profile.d/dotnet.sh > /dev/null
	sudo chmod +x /etc/profile.d/dotnet.sh
	sudo ln -s /usr/share/dotnet/dotnet /usr/bin/dotnet

sudo chmod +x /etc/profile.d/dotnet.sh
sudo ln -s /home/pi/.dotnet/dotnet /usr/bin/dotnet

So before I try Andy's github method, can you confirm what the revised code should be if the 'dotnet-install.sh' is sitting in the '/home/pi/' location?


Using the script as is, I do have a
NOTE: I can only see the 'dotnet-install.sh' in the 'home/pi location'.



Thanks for your help Mark

UPDATE- FAILED AGAIN

I've selected 'View', 'Show Hidden' and can see a ".dotnet' folder under 'Home/Pi/' which has several files and folders.

Still can't get anything from 'dotnet --version', or 'dotnet --info' though, just "bash: dotnet: command not found"

Have run the script Mark suggested which i think generated a 'dotnet' icon in the 'usr/bin' folder but with an exclamation mark.

The 'File Properties' of that icon, points to '/usr/share/dotnet' which is an empty folder.


Still trying things but been at this for sometime now.

DOES THIS MEAN SUCCESS?

I do hope so.

looks good - looks like progress

I will add though.... buster is now two pios versions behind - might be something to keep in mind for the future.

I did think about this. A clean install (bearing in mind my CMX runs on an external ssd, with the necessary changes made to identify that location and run it from there)?

Or

Update in situ to Bullseye?

Thanks
Martyn

[Nossie]

it's up to you - some would say if it's not broke, don't fix it - but if you are going to all the effort of changing from mono to dotnet \o/ and if it doesn't impact your existing cmx, why not?

Hi Martyn,

I am also running Buster. Would you mind providing a step-by-step instruction on how you eventually installed .Net 8. I've tried a few things without success and my Linux knowledge is fairly limited (been a Windows man for too many years).

Hi Trevor,

I am also running Buster. Would you mind providing a step-by-step instruction on how you eventually installed .Net 8. I've tried a few things without success and my Linux knowledge is fairly limited (been a Windows man for too many years).

Note that I do use the GUI version of RPi so can look into the file structure quite easily using 'Remote Desktop Connection'. For me I can see the results of using the command line, and also run the command line in the GUI environment. Like you, I struggle with many of the command line instructions.

I had to re-install .net again this morning, not through any problems with the previous install but for other reasons related to the O/S.

Again I followed the instructions to the letter (with a change to the installation directory noted in the instructions). In 'home/pi/' I could see the 'dotnet-install.sh' file, and after selecting 'View - Show Hidden' I realised that the '.dotnet directory' had not been created. The command 'dotnet --info' therefore drew a blank.

However I did note on my older Pi (with .net installed) that the directory size of '.dotnet' in the 'home/pi' was quite large and would presumably take time to create.


For ardent coders out there look away now!

After right clicking on the 'dotnet-install.sh' file in 'home/pi/', and 'Open' I ran the 'Execute' option, and it did take a short but noticeable time to install, but it worked straight away.

Not sure if I was impatient or not just using command line instructions, but I have to say that executing the script as I did worked first time.

Hope this helps

Martyn

Thanks Martyn. .Net 8 is now installed.

So I've got .Net 8 installed and have done a fresh install of CumulusMX. I've run the conversion utility on my data files but what command do I use to run Cumulus interactively? I didn't want to install it as a service until I was sure everything was working fine.

Trevor
