ubuntu snap package installation update and delete with simple use

An overview of the

What is snap? snap is a brand new package management approach. It is similar to having one container with all the files and libraries of one application, which are completely independent of each application. So the benefit of using the snap package is that it solves the dependency problem between applications, making it easier to manage between applications. The problem with this is that it takes up more disk space

The Snap installation package extension is.snap, which is similar to a container that contains all the files and libraries needed for an application (the snap package contains a proprietary root file system containing the dependent packages). They will be installed in a separate directory; Individual applications are isolated from each other. Using snap has many benefits. First, it solves the dependency problem of software packages. Second, it also makes the application easier to manage.

Not many applications now support snap. snap package 1 is installed in /snap

1 Some common commands

It's easy to use the snap package, so Let me introduce some common commands

sudo snap list

Lists the snap packages that have been installed

sudo snap find <text to search>

Search for the snap package to install

sudo snap install <snap name>

Install 1 snap package

sudo snap refresh <snap name>

Update one snap package, or all snap packages if you don't add the package name

sudo snap revert <snap name>

Restore 1 package to the previously installed version

sudo snap remove <snap name>

Delete 1 snap package

Simple use

To demonstrate how to install and remove a package, I will install an editor

First I want to install ES73en-ES74en

So first look for 1 to see if there is ES78en-ES79en

➜ bin sudo snap search hello-world
Name    Version Developer Notes Summary
hello-world   6.3  canonical -  The 'hello-world' of snaps
hello-world-om26er 0.2  om26er  -  A great snap
hello-lhc   1.0  cprov  -  Hello world application for LHC

Yes, there is. So let's install it

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

Downloading can be slow, so it's best to hang up the agent

And then let's see if 1 is installed

➜ bin snap list
Name   Version Rev Developer Notes
core   16-2.28.5 3247 canonical core
hello-world 6.3  27 canonical -

Finally, we delete it

➜ ~ snap remove hello-world
hello-world removed

One error

Since it took too long to install ES106-fm, I stopped the operation and later reported an error when installing the package again
error: cannot install "douban-fm": snap "core" has changes in progress

The solution is simple

First look at change in progress

➜ / snap changes

6 Doing 2017-11-15T03:34:27Z -      Install "douban-fm" snap

That's right install douban-fm It's still in doing, so abort the process

➜ / sudo snap abort 6
