WSL2- Ubuntu 20.04 Snap store doesn't work due to systemd dependency

[penavincent]

I just reinstalled ubuntu on WSL2 from scratch in order to upgrade to 20.04 with a clean slate. The main issue I've noticed has to do with a lot of packages moving to snap rather than being maintained on apt, which is how I imagine most people here install their packages.

In fact it seems like Ubuntu 20.04 LTS replaced the ubuntu software with snapcraft entirely. So it's obvious snap is becoming the 'default' of the distro.

The issue is that snap doesn't currently seem to work on wsl2 due to it's reliance on systemd. If I understand it correctly, the snapd service should be running in the background for it to work, which snapd already comes preinstalled, however snapd can't start due to WSL2 not having systemd.

So if I run the command snap find node for example, it gives me the following error message:

error: cannot communicate with server: Post http://localhost/v2/snaps/hello-world: dial unix /run/snapd.socket: connect: no such file or directory

Running the command sudo service snapd start simply responds with:

snapd: unrecognized service

However snapd is already installed.

Is there any plan to get this working in the future, or is it something that is in progress?

In my development flow, I like to use the chromium-browser on WSL2 with the X410 server in order to test my web apps in both Windows and Linux browsers, since they can reveal some bugs, like say, when uploading csv files files from a Windows browser, React can't really tell since Windows changes the MIME Type of the file, whereas Linux and Mac keep it the same and so it's easy to handle.

Now I can't really use chromium though, since I can't install it without snap anymore.

EDIT: After several hours of trying to fix it I came across several other issues from about 8-10 months ago, with the most popular solution being this, which seems to make some changed to PIDs to make it work, but it just seems so hacky, and it's not a permanent solution, as a restart will remove it.

• Windows Version: 10.0.19613.1000
• Ubuntu 20.04 WSL2

[sirredbeard]

This is something that is being looked at.

Implementing in a non-hacky way that can be supported long-term without a lot of secondary issues takes planning.

There is a workaround to get snaps working.

[jmoeyersons]

Is there any update about this issue available please?

[blackliner]

Here is the link to the scripted version of the workaround @sirredbeard mentioned: https://github.com/DamionGans/ubuntu-wsl2-systemd-script

[jramiresbrito]

Running on same error when trying to run snaps to download heroku cli.

Updates are welcome.

[fenris]

any update on this?

[mdtalhachy]

Still not working. When I run snap version, this appears:

I tried that on kali and it did not work. It basically kills the bash on the third command and I am back in the Powershell.
Is there an official ETA to really fix that?

@mahfuzullah I had this problem. I executed wsl --shutdown from windows cmd and then executed those commands again. Now without any login, everything works perfectly.

I had the same problem in Pengwin under WSL2, but before it exits the shell, I get the following message:

However, running snap version show valid information. Now when I run sudo snap list, I get:

When I run sudo snap login <email>, I get error: access denied (see 'snap help login').

Any ideas?

same problem

[theofaron]

Did you replace the placeholders with your values? You need to execute the first two commands. Then use top (or htop) to find out the PID of systemd and then use it to replace the $(pidof systemd) in the third command and replace $LOGNAME with your login name.

[Laxman-SM]

@theofaron thanks for the Hack,

Yes, I have tried it with the actual PID replacing the $(pidof systemd) and my username (rob) in place of the $LOGNAME. It had the same result. I also shutdown WSL 2 with wsl --shutdown and then tried again; I got the same result. I would love any further help with this. Thanks!

[SamLowryMOI]

I use this under Ubuntu 20.04.1 LTS. Maybe it doesn't work under Pengwin. Maybe you make a mistake. I'll show you my approach. Please reboot your pc to get a clean start point. I use the new terminal in windows.

The first command shows some output, no errors, ends with 'done'.
The second and third command show no output.
snap version and snap list work fine. No need to use snap login.

Ensure you use the right PID. After the second command use htop. Use F10 to filter the output. Type systemd. There are about eleven entries. Type a space (so you are filtering for 'systemd ', not for 'systemd'). Now there are only two entries. Use the pid for /lib/systemd/systemd.

If you done it all right I can't help you, it seems to be a problem with Pengwin, sorry.

[lxg208]

I have a strange problem, after running

sudo daemonize /usr/bin/unshare --fork --pid --mount-proc /lib/systemd/systemd --system-unit=basic.targe

my host name changed. It went from "TEST_server" to "TESTserver". What did I do wrong?

[jsanzdev]

The workaround doesn't work for me, I get stuck with the snap login, is there any solutions?

Snap needs systemd to work. Systemd support on WSL is only available on Windows 11.

You need the store WSL version and you should use ubuntu 22.04 which works out of the box

Note that Ubuntu 22.04 still requires the whole /etc/wsl.conf thing to enable systemd. For a trully out-of-the-box, no-steps-required experience use Ubuntu-Preview. It also fixes a couple services that fail on WSL.

Exited wsl and ran wsl --update in Powershell. Docker installed with snap after that with no issues.

[krave1986]

@mmiric-endava Do you have more info about wsl --update? Any docs maybe.

[mmiric-endava]

@mmiric-endava Do you have more info about wsl --update? Any docs maybe.

Yes, there are some details displayed by wsl --help and on Microsoft docs as well:

Update your WSL version to the latest version. Options include:

--web-download: Download the latest update from the GitHub rather than the Microsoft Store.

Essentially your wsl package is updated to the latest version.

[mickdewald]

Important:
Do not forget to exit wsl via wsl --shutdown after editing /etc/wsl.conf
Just exiting wsl via exit and entering via wsl is not enough

[cbouwense]

I went through all the steps outlined on this article Systemd support is now available in WSL! and it did not work. However I was doing this from a VSCode terminal running WSL. I opened a "normal" wsl window and it worked like a charm (Windows 10).

Hi everyone I try install k9s on WSL in that way:

after that, I do the command

I also tried most of the solutions documented here. ^THIS prompted me, in a not very hopeful way, to try switching from Windows Terminal + Pwsh + wsl to use the WSL console.... and it worked. I am not sure how I feel about it.
