Editor to share with you the ubuntu snap package installation, update deletion and use of the example analysis, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to know it!

Overview

What is snap,snap is a new way of package management, which is similar to a container with all the files and libraries of an application, which is completely independent of each application. So the advantage of using the snap package is that it solves the problem of dependencies between applications and makes them easier to manage. But the problem is that it takes up more disk space.

The installation package extension for Snap is .snap, which is similar to a container that contains all the files and libraries needed by an application (the snap package contains a private root file system that contains dependent packages). They are installed in separate directories; applications are isolated from each other. Using snap has many benefits: first, it solves the problem of package dependencies; second, it also makes applications easier to manage.

At present, there are not many applications that support snap. Snap packages are generally installed in the / snap directory.

Some commonly used commands

In fact, using the snap package is very simple. Let me introduce some common commands.

Sudo snap list

List the installed snap packages

Sudo snap find

Search for snap packages to install

Sudo snap install

Install a snap package

Sudo snap refresh

Update a snap package, if you don't add the name of the package, that is to update all snap packages

Sudo snap revert

Restore a package to a previously installed version

Sudo snap remove

Delete a snap package

Simple to use

Now I will install an editor to demonstrate how to install and delete a software package.

First I want to install hello-world

Well, let's find out if there is a hello-world.

➜bin sudo snap search hello-worldName Version Developer Notes Summaryhello-world 6.3 canonical-The 'hello-world' of snapshello-world-om26er 0.2 om26er-A great snaphello-lhc 1.0 cprov-Hello world application for LHC

Yes, there is, so let's install it.

➜~ snap install hello-worldhello-world 6.3from 'canonical' installed

Downloading may be slow, so you'd better hang up the agent.

Then let's see if it has been installed.

➜bin snap listName Version Rev Developer Notescore 16-2.28.5 3247 canonical corehello-world 6.327 canonical-

Finally, we delete it.

➜~ snap remove hello-worldhello-world removed

A false report.

Because it took too long to install douban-fm, I terminated the operation and reported an error when I installed the package again

Error: cannot install "douban-fm": snap "core" has changes in progress

The solution is simple.

First, take a look at the ongoing change.

Yes, install douban-fm is still in doing, so terminate the process.

➜/ sudo snap abort 6➜ / snap changesID Status Spawn Ready Summary2 Done 2017-11-15T02:33:51Z 2017-11-15T02:33:51Z Refresh all snaps: no updates3 Error 2017-11-15T03:20:07Z 2017-11-15T03:20:23Z Install "douban-fm" snap4 Done 2017-11-15T03:20:07Z 2017-11-15T03:20:10Z Initialize device5 Error 2017-11-15T03:20:38Z 2017-11-15T03:34:21Z Install "douban-fm" snap6 Error 2017 -11-15T03:34:27Z 2017-11-15T03:40:51Z Install "douban-fm" snap

Just perform the installation again after that.
