❔ ✅ Installing the .NET SDK on Ubuntu 23.04
Does anyone here have experience with installing .NET 7 on Ubuntu?
124 Replies
I followed the docs on MS but they are all over the place and nothing works.
It was this you followed?
https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu-2304#install-net
Yes
The install doesnt work - when I run dotnet --info after the install, its says no SDK found
I have been on it for 3 days - I have tried installs with apt and snap - neither work. I have reinstalled vscode a few times but that too cannot find the SDK. Logged to github but no one is picking it up
When you run sudo apt install again what's the output, does it say it installed something or that there was 1 not upgraded or whatever
Yes, it says the SDK is installed - but dotnet --info says its not and dotnet --list-sdks returns a blank line
And the PATH variable does not get added automatically to the ~/.bashrc file
And when I add the PATH manually it still doesnt work
you didn't install the runtime first and then the sdk after from different providers did you?
No, the runtime should install automatically ( which it does ) but the SDK does not install
so when I run dotnet --list-runtimes, the runtime shows
never try installing the runtime or SDK multiple different ways. it will never work. all but one installation is ignored
this is practically guaranteed to be your problem
I learnt that on day one. Then I set about removing all traces of .NET and started again.
so whats the solution?
The issue with multiple feeds was apparently fixed
i mean. you need to nuke everything .NET related on your computer and try again. if the instructions in the article don’t work then you need to figure out why they don’t work rather than try installing it a different way
I have nuked everything - there is not a single file or folder on the system with dotnet in the name
I must have gone through about 40 iterations of cleaning and reinstalling
I have decided the snap package manager does not work - so I have been trying only the apt one
yes, the snap is sort of broken unfortunately
But it looks like thats broken too
did you add the microsoft feed
I am staring down a full reinstall of Ubuntu which I would like to avoid
Yes, went down that route many many times
remove it
Yes, I have removed it
The only thing I havent tried is downloading the binaries and installing manually
do not do that either
Its crazy - why does MS not deal with this
because it works fine
It absolutely does not - check github
This issue is exactly the same as with 6.0 and Ubuntu 22.04 as well as 20.04
do you have
DOTNET_ROOT set in your environment variablesYes. I tried a number of differnt PATH statements inclusing DOTNET_ROOT
delete that
I have run every imaginable configuration of PATH statement on BOTH snap and apt installs. Nothing works
trying every combination is not the solution
you need to figure out why the recommended solution does not work
Yes, I am testament to that
I have spent 2 days trawling hundreds of posts - Its MS job to figure that out - not mine.
I dont have heavy skills in Linux scripting either.
make sure absolutely every dotnet environment variable, path, file is deleted and just install
dotnet-sdk-7.0 from the Ubuntu repos. if it’s broken we will figure out why it is brokenThe current state of the machine is clean - no mods to the ~/.bashrc and no dotnet files or folders
No point in following the docs - installing the dotnet-sdk-7.0 does not work
sudo apt-get install -y dotnet-sdk-7.0 does not work
I have also done resource ~/.bashrc to make sure the current state of the bashrc file is used
what about it does not work
its all in my third comment
Do you have actual experience with Ubuntu and the .NET 7.0 SDK ?
And running up a container is not the same as having a full Ubuntu install.
i just did this on my install of Ubuntu.
as you can see the SDKs and the runtimes both work perfectly. the fact that it does not work for you means your machine's configuration is screwed up somehow. we can either figure out what's wrong or you can sit here and complain about how microsoft should fix your computer for you
i much prefer the first option
Can you run dotnet --info ? Does it say a SDK was found?
I am not running a macbook
That command does not work on my machine although it says it does
And what version of Ubuntu are you running? - this command worked perfectly for me on 22.04
i'm on 22.04. are you on a different version?
Yes, 23.04
Yes, it works for you. It worked for me too on 22.04
can you check if the PATH was updated/added in your bash?
Looks fine -
so, after you install the package, when you do
dotnet --list-sdks, it says you have noneit just returns a blank line
dotnet --info says there is no SDKs found
but it does find the runtime
what does
ls /usr/lib/dotnet/sdk give youls: cannot access '/usr/lib/dotnet/sdk': No such file or directory
The machine is clean
echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/home/greg/.dotnet/tools
whereis dotnet
dotnet: /etc/dotnet
if you still have the
dotnet program then the machine isn't cleanecho $DOTNET_ROOT returns a blank line
hmmm - i didnt clean .dotnet folders
what does
ls /etc/dotnet give youinstall_location install_location_x64
you definitely need to nuke that folder too
ok
rm: cannot remove 'install_location': No such file or directory
just
sudo rm -rf /etc/dotnetls /etc/dotnet
ls: cannot access '/etc/dotnet': No such file or directory
i guess you already deleted it then
yes
now
whereis dotnet is empty right? if you do dotnet then it'll tell you dotnet is not found, right?whereis dotnet
dotnet:

Command 'dotnet' not found, but can be installed with:

seems like it's working
No SDKs found
oh
i see
try
echo $DOTNET_ROOTblank like
same with dotnet --list-sdks
can you reopen your terminal and try again
dotnet --list-runtimes
Microsoft.AspNetCore.App 7.0.11 [/usr/lib/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 7.0.11 [/usr/lib/dotnet/shared/Microsoft.NETCore.App]
reopened terminal and cleaned and installed - same
So , the runtime is installed but not the SDKs
okay. what is
ls /usr/lib/dotnet/sdkls: cannot access '/usr/lib/dotnet/sdk': No such file or directory

Its big
do they mostly start with /usr/lib/dotnet/sdk/7.0.111/
here is a sample
sorry - cant send - server is blocking it
/usr/share/dotnet/sdk/7.0.401/Containers/containerize/Microsoft.Build.Framework.dll
hmmmmmmm
/usr/share/dotnet/sdk/7.0.401/DotnetTools/dotnet-format/ru/Microsoft.CodeAnalysis.Features.resources.dll
ls /usr/share/dotnetCan you test this inside a 23.04 container?
ls /usr/share/dotnet
sdk sdk-manifests templates
if it really installed to
/usr/share/dotnet instead of /usr/lib/dotnet this would explain the issue
indeed, that seems to be the issue
so, it's isntalling the SDK to a different place from the runtime
now the question is, whyok
so why does it work for you?
Is this only on 23.04?
or is it the package causing the issue
ah. 7.0.401
i see the issue
the SDK is coming from the micrisoft repos
but the runtime is coming from the ubuntu repos
aha
the ubuntu repos onl have 7.0.1xx so that is for sure the issue
they were supposed to fix this - there was a github issue that was closed on this
try just to remove everything dotnet related. make sure
/usr/share/dotnet is gone once you do that

okay. now you can try
sudo apt install dotnet7wooohooo
you did it!
no idea how you did it but you did
thanks -
summary?
i mean, it's the same issue as most other people are having--the .NET SDK was coming from the microsoft repos, but the runtime was coming from the Ubuntu repos, and the two do not mix because they install to different folders
https://learn.microsoft.com/en-Us/dotnet/core/install/linux-package-mixup?pivots=os-linux-other#whats-going-on
for you it seemed to have installed some packages from Ubuntu and some from Microsoft. i do not know why exactly it chose to do this, but it shouldn't be able to in the first place
OK - I respect your tenacity and help
anyway, just deleting the microsoft repo and reinstaling everything makes it work. in the future, if you need the microsoft repos for some other software--maybe you want PowerShell or SQL Server--you will need to make sure it does not start pulling dotnet from there
will do - Thanks again
quick question - do I need to manually update the PATH?
no
dotnet is put into /usr/bin which is installed into the PATH alreadyok
👍
If you were in France, you would be getting a special bottle of wine!
i'm glad i could help!
