Runtime: dotnet: command not found after installing dotnet core 2 on ubuntu linux 16.04

[Petermarcu]

@andremarcondesteixeira opened this issue here: https://github.com/dotnet/core/issues/1012

I followed the steps in https://www.microsoft.com/net/core#linuxubuntu to install dotnet core 2 (dotnet-sdk-2.0.0) in my machine, which has an Ubuntu Linux 16.04.

Tried it 3 times, and certified that I was executing the commands for my distro and that any previous version was uninstalled, but no success.

Expected Behavior:
running dotnet in the command line returns me the helper page of dotnet

Actual Behavior:
running dotnet in the command line gives an error dotnet: command not found

Also, the docker package on the official site gets me dotnet core version 1.x, and the docker package with the version 2 (sdk) does nothing when I run it.

What does env | grep PATH say? What does dpkg-query -L dotnet-sdk-2.0.0 say?

result of env | grep PATH:

result of dpkg-query -L dotnet-sdk-2.0.0 follows in attached file

[andremarcondesteixeira]

note: the issue with docker is solved. Currently the only issue I'm having is not being able to run dotnet on my local machine after installation

[omajid]

Thanks. This looks okay. What does dpkg -L dotnet-host and type dotnet say?

[andremarcondesteixeira]

result of dpkg -L dotnet-host:

andre@andre-RV411:~/projects/currency$ dpkg -L dotnet-host /. /usr /usr/bin /usr/share /usr/share/man /usr/share/man/man1 /usr/share/man/man1/dotnet.1.gz /usr/share/doc /usr/share/doc/dotnet-host /usr/share/doc/dotnet-host/changelog.Debian.gz /usr/share/doc/dotnet-host/copyright /usr/share/dotnet/dotnet /usr/share/dotnet/LICENSE.txt /usr/share/dotnet/ThirdPartyNotices.txt /usr/bin/dotnet

and running type dotnet returns me bash: type: dotnet: not found

[andremarcondesteixeira]

any news on this?

[omajid]

Hm. PATH includes /usr/bin and dpkg says there is a file /usr/bin/dotnet present. But type says it cant execute it? Can you confirm this? What does ls -l /usr/bin/dotnet say? And what happens if you run /usr/bin/dotnet --info?

[leecow]

Omair is pointing at questions I have as well - particularly, where is /usr/bin/dotnet pointed. There were some changes in 2.0 which make things much less forgiving.

[andremarcondesteixeira]

running ls -l /usr/bin/dotnet returns me:

andre@andre-RV411:~$ ls -l /usr/bin/dotnet lrwxrwxrwx 1 root root 24 Out 4 23:42 /usr/bin/dotnet -> /usr/share/dotnet/dotnet

and running /usr/bin/dotnet --info gives me bash: /usr/bin/dotnet: No such file or directory

[andremarcondesteixeira]

I need to mention that I uninstalled the previous dotnet version using sudo apt-get purge dotnet (I don't know if this matters)

[andremarcondesteixeira]

additional info in attached file. Looks like there is no dotnet inside /usr/share/dotnet (so /usr/share/dotnet/dotnet does not exist)
output.txt

andre@andre-RV411:~$ /usr/share/dotnet/dotnet bash: /usr/share/dotnet/dotnet: No such file or directory

[andremarcondesteixeira]

actually, it looks like that the dotnet binary is missing in my installation for some reason :(

[andremarcondesteixeira]

I just tried installing the three packages listed in the dotnet core-setup github page:

Host (Checksum)
Host FX Resolver (Checksum)
Shared Framework (Checksum)

and now, the problem seems to be solved.
I wish that installing using apt-get was enough, though.

[andremarcondesteixeira]

Now I'm running into folder permission issues:

`andre@andre-RV411:~/projects/health-platform/aspnet-core$ dotnet restore

Permission denied to modify the '/usr/share/dotnet/sdk/NuGetFallbackFolder' folder.

Here are some options to fix this error:

1. Re-run this command with elevated access.
2. Disabled the first run experience by setting the environment variable DOTNET_SKIP_FIRST_TIME_EXPERIENCE to true.
3. Copy the .NET Core SDK to a non-protected location and use it from there.
   `

[Petermarcu]

Thats an SDK issue I believe. It needs to write something to an admin location. Can you do dotnet/core-setup#1? @livarcocc any input?

[andremarcondesteixeira]

@Petermarcu I did dotnet/core-setup#1 :D
worked 🕺

[EmelyanovRoman]

If there somebody siting on opensuse 42.3 https://github.com/dotnet/core/blob/master/release-notes/download-archives/2.0.5-download.md
Installing from tar helped me.
Of course after delete previous version of dotnet.
Sorry for my english.
UPD: in Visual studio Code need to update PATH >_< I dont know why :(

[superted17]

You can get into this situation if you install dotnet core 2 without removing dotnet core 1 first.

Some versions of dotnet core 1 installed into /usr/local/bin/, whereas dotnet core 2 installs to /usr/share/.

You can fix this simply by adding a symlink to the new install location:

sudo ln -s /usr/share/dotnet/dotnet /usr/local/bin/dotnet

[rakeshsinghranchi]

@superted17 , Thanks for sharing the resolution.Can you please share the repro steps ? I am unable to repro the issue at my end.

[superted17]

@rakeshsinghranchi it's hard to say. The machine that had the problem had dotnet core 1 installed (not even sure which version). I followed the official installation steps to install dotnet core 2 and ran into this problem.

All I can do is make a suggestion:

After installation, have some script use the output of "whereis ls dotnet" to verify that the path ties up with the expected install path. If not, add a symlink.

[leecow]

Will add a note to known issues docs for troubleshooting this issue.

[VladDerptastic]

@superted17 May I ask what would be the same solution for a Windows 10 machine?

[gpiepenbrink]

sudo ln -sf /usr/share/dotnet/dotnet /usr/local/bin/dotnet
