Install snapd on CentOS

snapd
21

Testing packages are now available from my COPR repository.

To install with full GNOME Software integration, here are the following steps:

# Install the COPR plugin and EPEL
$ sudo yum install yum-plugin-copr epel-release
# Enable this repo
$ sudo yum copr enable ngompa/snapcore-el7
# Install snapd
$ sudo yum install snapd
# Enable snapd.socket
$ sudo systemctl enable --now snapd.socket
# Install GNOME Software snap plugin, note that GNOME Software gets replaced in this step
$ sudo yum install gnome-software-snap

Feedback on the packages would be greatly appreciated.

I’ll give this a try :smiley:

23

It fails on lack of squashfuse and policycoreutils-python-utils

EDIT: Wti the new epel-release package I’m only missing policycoreutils-poython-utils.

24

This should be fixed now, with the new build of snapd.

25

I got into selinux problems with startup of snapd-login-service but otherwise things do work OK. I tried spotify (installed from command line) and slack. I’ll continue testing.

EDIT: some more selinux woes.

Works great for us!

We just setup a test runner for Centos 7 using your snapd packages and now have automated testing of LXD on Centos 7 on all channels and tracks.

Getting the kernel on Centos 7 to behave with user namespaces is always entertaining (because that keeps changing somehow), but once you have the right set of boot parameters and sysctls, everything works fine.

For the latest result for the LXD snap in the latest track and edge channel.

@stgraber

How those jenkist builds can be downloaded ? Is there rpm repo for CentOS 7 ?

29

Jenkins validates that the LXD snap works on Centos 7.
There are no RPMs for LXD on Centos, only the snap.

Installation instructions for the LXD snap on Centos 7 can be found here:

How do I install newest snapd for CentOS 7 ? So I can install snap packages after that?

31

Is this still newest?

I have not usually installed that GNOME Software Integration, I don’t know does it work at all.

Without that step, I could install for example Wekan snap like this:

34

Unfortunately, I can’t yet fix this until CentOS 7.5 is available, since I need to rebuild against the EL7.5 environment to fix it. Hopefully, it should be available before the end of the month.

35

I forgot about the lag from RHEL to CentOS releases. In any case, I was still able to install Snap and then was able to install Hiri (a great e-mail client with solid MS Exchange support, btw). The manual install for Hiri failed so Snap let me try out an application I would have otherwise given up on. As @xet7 mentioned, the Gnome integration is not essential.

Thanks!

Thank you @Conan_Kudo, the instructions help install snapd all the way … However facing issues installing mailspring (which required snap to be installed 1st). Following is the error in getting:

root@vps [~]# sudo snap install mailspring
error: cannot perform the following tasks:

  • Mount snap “core” (5328) ([start var-lib-snapd-snap-core-5328.mount] failed wi th exit status 1: Job for var-lib-snapd-snap-core-5328.mount failed. See “system ctl status var-lib-snapd-snap-core-5328.mount” and “journalctl -xe” for details.
    )

Would appreciate some assistance with this…

Hi Conan_Kudo – I was just wondering if there will be a build of the latest snapd for your COPR repo and CentOS 7.5? Lots of bug fixes since the 2.30 build now available. Thanks for getting this to work for everyone!

My COPR repository is no longer required to get the core snapd software. It is now part of Fedora EPEL, though it requires RHEL/CentOS 7.6 or higher.

Details are available in the official snapd EPEL updates forum topic.
