In snap: "error: unknown flag hold"

rated 0 times [ 1] [ 0] / answers: 1 / hits: 427 / 2 Years ago, mon, june 20, 2022, 4:53:52

Snap automatic updates can now be disabled with $ sudo snap refresh --hold.

This can be seen in this other thread and this blog post and from the mouth of the horse itself.

My Ubuntu 22.04 is up to date but I get an error when running the command. Any idea why?

$ sudo apt update

...

All packages are up to date.



$ sudo snap refresh

All snaps up to date.



$ sudo snap refresh --hold

error: unknown flag `hold'

Quoting from the third link in your question:

Refresh hold

The new hold feature allows system administrators and end users to
stop or postpone their snap updates for as long as necessary.

Searching around a bit, The snapd roadmap indicates that the refresh --hold feature was added in version 2.58. Meanwhile, Ubuntu 22.04 currently provides 2.56 at the latest:

$ apt policy snapd

snapd:

  Installed: 2.56.2+22.04ubuntu1

  Candidate: 2.56.2+22.04ubuntu1

  Version table:

 *** 2.56.2+22.04ubuntu1 500

        500 http://archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages

        100 /var/lib/dpkg/status

     2.55.3+22.04 500

        500 http://archive.ubuntu.com/ubuntu jammy/main amd64 Packages

So, your version simply doesn't support the feature.

In Ubuntu 22.10:

$ apt policy snapd

snapd:

  Installed: 2.57.5+22.10ubuntu0.1

  Candidate: 2.57.5+22.10ubuntu0.1

  Version table:

 *** 2.57.5+22.10ubuntu0.1 500

        500 http://archive.ubuntu.com/ubuntu kinetic-updates/main amd64 Packages

        500 http://archive.ubuntu.com/ubuntu kinetic-security/main amd64 Packages

        100 /var/lib/dpkg/status

     2.57.4+22.10ubuntu1 500

        500 http://archive.ubuntu.com/ubuntu kinetic/main amd64 Packages

So, even Ubuntu 22.10 does not have this option.
