No longer install latest htop snap - depends on core22

snapd

I can no longer install the latest htop snap on Rocky Linux 8.6 with latest available snapd. Other snaps installed without problems.

I get this:

→ snap install htop
error: cannot perform the following tasks:
- Ensure prerequisites for "htop" are available (cannot install snap base "core22": snap "core22" assumes unsupported features: snapd2.55.5 (try to refresh snapd))

You need snapd in version at least 2.55.5. I’ve pushed out updates to 2.56.2 as described here: Snapd updates in Fedora EPEL for Enterprise Linux you’re welcome to try them and post karma in bodhi so that the updates each stable sooner.

@mborzecki Thanks. I’ll have a look. BTW what is the difference between the RPM package that I initially install and when snap updates itself to a later version? Does snapd not then become the updated version?

For interest sake. I’m also running some Amazon Linux servers with an older build of snapd but they can install the htop package and core22.

This may be an older revision of core22. The change to require snapd 2.55.5 was introduced just recently. Since it’s also running an older snapd, updating core22 will be blocked until snapd gets an update.

I just had a look. The snap installed was the same version of core22 on both the hosts. The one, Rocky Linux 8, with the test rpm and the other was the Amazon Linux 2 host with the 2.54.3-1 rpm.

I have an old test ubuntu 16.04 and it installed the core22 and htop package too.

Ubuntu can reexec from the snapd snap, effectively speeding up the update process.

FYI, we have just pushed an update to the Amazon Linux 2 package which is accessible from the Unofficial snapd repository for Amazon Linux 2

Thank you! I appreciate your feedback.
