Core: Script tries to downagrade .NET Standard 2.1 Targeting Pack

Created on 8 Apr 2020  路  14Comments  路  Source: dotnet/core

Issue Title

Script tries to downgrade .NET Standard but it fails.

General

Your instalator script fails when trying to install packages on deb-based distro - Mint 19.4.
You missed there __--allow-downgrades__, so it can downagrade to older .NET Standard Targeting Pack package of version 2.1.
As far as I remember .NET 3.1 was able to use .NET Standard 2.2 so why are you downgrading to 2.1 on .NET 5?

Correct me if I am mistaken.

.NET Standard 2.1 is the latest version, and .NET Standard 2.2 shouldn't exist. If 2.2 did exist, it would actually install side-by-side with 2.1 and not cause any conflict, because they have different package names, netstandard-targeting-pack-2.1 and netstandard-targeting-pack-2.2. I think what's actually happening for you is a difference between the version of netstandard-targeting-pack-2.1 you have installed vs. the version that's included with the 5.0 preview tar.gz files. (We redistribute the latest version so that the tar.gz contains everything you need to install the 5.0 preview.)

@Arkasian can you provide some more detail, such as ~the Linux distro you're using~(edit: apologies, just spotted you provided this, Mint 19.4), which package you have installed before running the script, and more complete console output? (Copy paste is much more preferable to a screenshot!)

Sorry, dont have an output, didnt have it at the time of writing the issue either, because I closed terminal just after the fact. There was nothing more than what I showed, just standard log for every installation of .NET Core, and then it printed out what I showed.
I had installed there .NET Core 2.2.402 SDK and compatible runtime.
dotnet-sdk-2.2, aspnet-runtime-2.2 dotnet-runtime-2.2 and those are all I had installed on my system. I will try reproduce that error again, but Im not sure if I will be able to.

I just had the same issue crop up on TravisCI: https://travis-ci.org/github/demystifyfp/FsToolkit.ErrorHandling/builds/686310362

My current .travis.yml file:

sudo: false # use the new container-based Travis infrastructure
dist: xenial
dotnet: 3.1.200

before_script:
  - nvm install 10.15.0

  - mkdir $HOME/dotnet_install && cd $HOME/dotnet_install
  - "curl -H 'Cache-Control: no-cache' -L https://aka.ms/install-dotnet-preview -o install-dotnet-preview.sh"
  - sudo bash install-dotnet-preview.sh

Had this same issue on Debian 10 when trying to upgrade preview 5 to 6, and again now when I tried upgrading preview 6 to 7.

I run both .net core 3.1 application and preview 5.0 application on same machine

Here's the first output:

Here's a simple repro command for Debian 10 isolated in Docker, if it helps, @NikolaMilosavljevic @leecow. It uses the artifacts directly rather than running through the full script for simplicity.

The versions being exactly the same (2.1.0-1) yet still causing this error is surprising and doesn't match up to my theory above... not sure what's going on here but perhaps the error message shouldn't necessarily be trusted:

docker run -it --rm debian:10 bash -c '
  set -x
  apt update
  apt install -y wget
  wget https://packages.microsoft.com/config/debian/10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb

Again, bumped into this on Debian Buster and discovered this GitHub issue. With the packages from .NET Core 3.1 SDK installed, I get this exact error and can reproduce the error easily:

Using dpkg - works fine

If I instead switch to using dpkg instead of apt (which feels more natural with local packages IMHO), it works flawlessly:

Update: I discovered the --verbose-versions flag in apt, which gives us this, shedding some further light on this weird, weird issue:

This almost feels like a bug in apt-get to me. If someone feels like it, it would make sense to report this to Debian upstream as well.

If I instead switch to using dpkg instead of apt (which feels more natural with local packages IMHO)

I don't think we can just do this: dotnet-runtime-deps-5.0 depends on distro-provided library packages that need to be installed from the distro repositories for .NET to be able to run. My understanding is that dpkg would just complain, then you'd have to install all those packages manually and run the script again, or something like that.

This is interesting though, and maybe a hybrid/more complex approach would be a viable workaround.

If someone points me to the install-dotnet-preview.sh script

AFAIK this script isn't maintained on GitHub, but I believe @leecow and @rbhanda own it and may accept a patch anyway.

Very good point. I agree, flawed logic on my behalf. :see_no_evil:

I looked a bit more now and here is the URL to the "official", released version of this package (coming from packages.microsoft.com):

Do note the MD5 checksum there at the end (83005b6765f03ca8c6d07d9b01b3ad71).

But if I check with the package being downloaded from this script:

$ sudo md5sum dotnet_packages/netstandard-targeting-pack-2.1_2.1.0-1_amd64.deb

...it's something completely different. The file size is different also.

The package in the distribution seems to be built at 2019-09-18:

As for the checksums being different, I guess it _could_ be that apt (which is a more recent, high-level tool) is more strict here than dpkg; dpkg can be seen as the more "raw" utility here, with capabilities to fully destroy your system if you just give it the right parameters. :smirk: Different MD5 checksums/older content => it could be that it's smart enough to understand that this is somehow a "downgrade" perhaps? (even though "downgrade" is not technically 100% accurate...)

Conclusion

Re-publishing a package with the exact same version number but with different content seems a bit odd on our behalf. Given these facts, I will not proceed with reporting this to Debian at this point. Could someone with enough insight into this try to dig in and figure out where the .deb package inside https://dotnetcli.blob.core.windows.net/dotnet/release/install-preview/5.0.0-preview.8/dotnet-5.0.0-preview.8-deb.tar.gz is coming from? And try to update it with the correct, officially released version of this package (i.e. https://packages.microsoft.com/debian/10/prod/pool/main/n/netstandard-targeting-pack-2.1/netstandard-targeting-pack-2.1.0-x64.deb).

Ping @rbhanda, any updates on this?

perlun picture perlun on 18 Sep 2020

Are you still seeing this issue with .NET 5 RC 1 update?

rbhanda picture rbhanda on 18 Sep 2020

Works for me now on .NET 5 RC 1

@rbhanda Trying it now. (As a side note, the dotnetcli.blob.core.windows.net host is horribly slow btw, I get download speeds in the 2-3 Mbit/s range - would be great to get proper CDN acceleration on these builds as well.)

Anyway, looks much better on the new version (except for the notice at the end):

(Notices are probably mostly harmless, but could still be worth investigating what is causing this:)

N is for notices. A notice is something that the program wants you to be aware of but that is not a warning. A typical notice from apt is N: There is 1 additional version. Please use the '-a' switch to see it.

As for the contents of the archive, it does look a bit dubious still:

Note the strange dotnet_packages/._netstandard-targeting-pack-2.1.0-x64.deb entry there. Seems like a mistake?

$ file dotnet_packages/._netstandard-targeting-pack-2.1.0-x64.deb 
dotnet_packages/._netstandard-targeting-pack-2.1.0-x64.deb: AppleDouble encoded Macintosh file

The rahulbhandari/staff ownerships there also looks a bit odd, compared to the root/root in the previous example. I guess this archive was manually created by you @rbhanda, after inspecting the contents of the files or something?

The netstandard-targeting-pack-2.1.0-x64.deb file

As for the dotnet_packages/netstandard-targeting-pack-2.1.0-x64.deb file itself, it looks much better this time. It's definitely the same file as coming from packages.microsoft.com:

$ ls -l dotnet_packages/netstandard-targeting-pack-2.1.0-x64.deb 
-rw-r--r-- 1 501 staff 1474124 sep 12 02:22 dotnet_packages/netstandard-targeting-pack-2.1.0-x64.deb
$ md5sum dotnet_packages/netstandard-targeting-pack-2.1.0-x64.deb 
83005b6765f03ca8c6d07d9b01b3ad71  dotnet_packages/netstandard-targeting-pack-2.1.0-x64.deb

So, bottom line: the bigger problem has been resolved AFAICT. These minor issues pointed out here are more of an annoyance than anything else; it doesn't affect the end-user experience of being able to install/not install the packages => much better than in the Preview version. If I was maintaining the install experience, I would still give it a look though, to avoid the install looking slightly "weird" to more experienced users.
