First tried these instructions https://learn.microsoft.com/en-us/dotnet/core/install/linux-fedora?tabs=dotnet10

sudo dnf install dotnet-sdk-10.0
Last metadata expiration check: 0:25:01 ago on Sun Dec 14 20:35:48 2025.
No match for argument: dotnet-sdk-10.0
Error: Unable to find a match: dotnet-sdk-10.0

So next tried manual approach using these instructions https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual

wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh
chmod +x ./dotnet-install.sh
./dotnet-install.sh --version latest

Result is:

@genifycom - Can you please rerun the install script with --verbose and respond with the output?

[genifycom]

Certainly

./dotnet-install.sh --version latest --verbose
dotnet-install: Note that the intended use of this script is for Continuous Integration (CI) scenarios, where:
dotnet-install: - The SDK needs to be installed without user interaction and without admin rights.
dotnet-install: - The SDK installation doesn't need to persist across multiple CI runs.
dotnet-install: To set up a development environment or to run apps, use installers rather than this script. Visit https://dotnet.microsoft.com/download to get the installer.

./dotnet-install.sh: line 1057: find: command not found.

You need to install findutils. I verified this locally by uninstalling findutils, and it resulted in the same error you’re experiencing. Reinstalling it resolved the issue.

[genifycom]

Awesome, thanks Ella. Still getting used to Linux.

Perhaps the script could do one of its checks (like checking for curl) and include findutils in that part?

Like "dotnet-install: Calling: machine_has findutils"

[ellahathaway]

No problem!

Perhaps the script could do one of its checks (like checking for curl) and include findutils in that part?

Thanks for your suggestion. I agree—it would be really helpful for the script to handle situations like this a bit more smoothly. Right now, though, the scripts are in maintenance mode, so we're mostly focused on fixing urgent bugs and helping out with any issues that come up. Because of that, we probably won’t be able to tackle this improvement at the moment. That said, you’re more than welcome to open an issue or PR if you’d like—we’re always happy to take a look and triage suggestions.

Oh how come they are in maintenance mode? Any news about when they would leave maintenance mode?

[genifycom]

One more question please Ella

The default manual install of dotnet 10 i.e. ./dotnet-install.sh --version latest
installs to /root/.dotnet/sdk/10.0.101
and in my case neither of these report this installation:

dnf list installed | grep "dotnet"
or
dotnet --info

OTOH

The default install of dotnet 8 i.e. sudo dnf install dotnet-sdk-8.0
install to /usr/lib64/dotnet/sdk/8.0.117

Both dnf and dotnet see this installation.

Is this intentional?
