Unable to run a fresh new project on linux #4969

Current behavior

New project created via CLI on linux, .net 5 appears to have issues running.

Expected behavior

Just a simple startup of the default project template.

How to reproduce it (as minimally and precisely as possible)

mkdir gerty
cd gerty
dotnet new unoapp
cd gerty.Skia.Gtk 
dotnet run

Anything else we need to know?

Everything was performed command line, but it's worth noting that I intend on using Rider on linux. I'm running on pop!_os (Ubuntu) 20.10 with snaps enabled. Using the official .net core snap.

Yeah, so it looks like having both was messing things up. I removed the snap, and reinstalled dotnet, and things are working again. Thanks for the help debugging, guys!

Thanks for trying Uno!

The message in question explain that you need to have the .NET Core 3.1 SDK installed to get the project compiled.

You have two choices, either:

Install .NET Core 3.1 SDK: https://platform.uno/docs/articles/get-started-with-linux.html#setting-up-for-linux
Update your project to use .NET 5 (change netcoreapp3.1 to net5.0 in your gerty.Skia.Gtk project)

Updated to net5.0, next error is this in the template:

Thanks for the update. It looks like you're missing the installation of GTK3. Did you install it through apt ?

This version of pop!_os uses gnome 3.38.1. Safe to assume I have GTK? 😆

We'll search for the resolution our side, but in the meantime could you try installing the GTK dev package as well ? Could be ubuntu 20.04 related.

sudo apt-get install libgtk-3-dev

@atrauzzi Could you try to use .NET without snaps? As the pop!_os is derived from Ubuntu following this here (https://docs.microsoft.com/dotnet/core/install/linux-ubuntu#2010-) shouldn't cause any issues.

Snaps use a kind of containerization, I'm not sure if this is the cause but probably inside the snap container you don't have access to the host GTK dependencies. Let me know if without snaps this works.

@atrauzzi interesting, and the path of the lib is the same from here?

I'm using the Ubuntu 21.04 without issues so far. I will try this behavior with Ubuntu 20.10 in a Docker container to see if I can reproduce

@atrauzzi could you also share the return from ls -lah /usr/lib/x86_64-linux-gnu/libgtk*:

and also from ldd /usr/lib/x86_64-linux-gnu/libgtk-3.so.0 (this must have many lines, better send text instead image)

thanks

@atrauzzi thanks for sharing the information. I was suspecting the case that some dependency on libgtk-3.so.0 is not being resolved, but from the ldd return is all there.

The next alternative would be some dependence on the gtk dependencies not being resolved, but I really think this is unlikely to be true.

Could you do another test please? Publish the project with:

dotnet publish -r linux-x64

After that run the following command with strace:

strace bin/Debug/net5.0/linux-x64/publish/gerty.Skia.Gtk 2>&1 | grep libgtk

And sorry for asking for so many tests, I'm trying to understand the scenario since I couldn't reproduce on my side. Thanks!

@atrauzzi thanks, as expected the issue is not in the libgtk-3.so.0 it is being found:

openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libgtk-3.so.0", O_RDONLY|O_CLOEXEC) = 38

Ok, so the next step will be to run the strace without the grep (many many lines). But we will have a better clue of the root cause of the issue:

strace bin/Debug/net5.0/linux-x64/publish/gerty.Skia.Gtk 1> strace.log 2>&1

After that share with me the strace.log file.

It looks like it segfaults at the end of the file.

@atrauzzi yeah now it's complaining that the system doesn't have the ICU packages, please check if you have installed the:

sudo apt get install libicu67

@atrauzzi ok, 🤷‍♂️ it is also there, it's strange let me analyze the strace more calmly.

@atrauzzi interesting, it finds the library, but is also looking inside /snap/core18/current/lib/:

And apparently your system is looking for libraries first on /snap instead of /usr/lib or /lib. And I'm not sure why.

openat(AT_FDCWD, "/snap/core18/current/lib/x86_64-linux-gnu/libdl.so.2", O_RDONLY|O_CLOEXEC) = 3
read(3, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0P\16\0\0\0\0\0\0"..., 832) = 832
fstat(3, {st_mode=S_IFREG|0644, st_size=14560, ...}) = 0
mmap(NULL, 2109712, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x7ffb293d9000
mprotect(0x7ffb293dc000, 2093056, PROT_NONE) = 0
mmap(0x7ffb295db000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x2000) = 0x7ffb295db000
close(3)                                = 0
openat(AT_FDCWD, "/snap/core18/current/lib/x86_64-linux-gnu/libstdc++.so.6", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=107003, ...}) = 0
mmap(NULL, 107003, PROT_READ, MAP_PRIVATE, 3, 0) = 0x7ffb29a08000
close(3)

The process is turning into a mixed mess of /snap/ and /lib/ libraries, and I think this is coming into conflict.

Since it seems Snap related, here's an Uno app built using Gtk: https://github.com/unoplatform/calculator/blob/uno/build/snap/snapcraft.yaml

I used to use the dotnet snap, but I switched to the regular deb installation. Any chance there's maybe some lingering state somewhere?

I think if you ran snap remove it should clean up the things 🤷‍♂️, I think that in your case the dotnet is still running inside the snap sandbox.

Yeah, so it looks like having both was messing things up. I removed the snap, and reinstalled dotnet, and things are working again. Thanks for the help debugging, guys!
