So I was investigating via GNOME’s Disk Usage Analyser to find out which package is consuming the precious SSD space. Apart from the usual cache and home directory – to my surprise, I found that Snap and Flatpak consume a considerable amount of storage space. - -![Snap size – before cleanup][1] - -Although, I always maintain a rule – not to use Snap or Flatpak unless necessary. This is mainly because of their installation size and other issues. I prefer vanilla deb and rpm packages. Over the years, I have installed and removed a certain amount of Snap packages in this test system. - -The problem arises after uninstallation; Snap keeps some residue files in the system, unknown to the general users. - -So I opened the Snap folder `/var/lib/snapd/snaps` and discovered that Snap is keeping track of older versions of previously installed/uninstalled packages. - -For example, in the below image, you can see GNOME 3.28, 3.34, and Wine – all of these are removed long back. But they are still there. Its happening because of the Snap design which keeps versions of uninstalled packages after a proper uninstallation. - -![Files under snaps directory][2] - -Alternatively, you can get the same in terminal using: - -``` -snap list --all -``` - -![snap list all][3] - -The default value is 3 for several revisions for retention. That means Snap keeps 3 older versions of each package, including the active version. This is okay if you do not have constraints on your disk space. - -But for servers and other use cases, this can easily run into cost issues, consuming your disk space. - -However, you can easily modify the count using the following command. The value can be between 2 to 20. - -``` -sudo snap set system refresh.retain=2 -``` - -### Clean Up Snap Versions - -In a post in SuperUser, Popey, the ex-Engineering Manager at Canonical, [provided a simple script][4] that can clean up old versions of Snaps and keep the latest one. - -Here’s the script we will use to clean the Snap up. - -``` -#!/bin/bash - #Removes old revisions of snaps - #CLOSE ALL SNAPS BEFORE RUNNING THIS - set -eu - LANG=en_US.UTF-8 snap list --all | awk '/disabled/{print $1, $3}' | - while read snapname revision; do - snap remove "$snapname" --revision="$revision" - done -``` - -Save the above script as .sh in a directory (for example`clean_snap.sh` ), give it executable permission and run. - -``` -chmod +x clean_snap.sh -``` - -When I ran the script, it reduced a lot of disk space. The script would also show the name of the package being removed. - -![Executing the script][5] - -![Snaps size after cleanup][6] - -### Closing Notes - -There are always debates on how efficient Snap’s design is. Many say it is broken by design, bloated, and heavy on systems. Some part of that argument is true, I would not deny it. The whole concept of sandboxing applications is great if implemented and enhanced properly. I believe, Flatpak does a better job compared to Snap. - -That said, I hope this helps you clean up some disk space. Although it is tested in Ubuntu, it should work in all Linux distribution that supports Snap. - -Also, check out our guide on [how to clean up Ubuntu][7] with additional steps. - -Finally, if you are looking for cleaning up **Flatpak** apps, refer [this guide][8]. - --------------------------------------------------------------------------------- - -via: https://www.debugpoint.com/clean-up-snap/ - -作者：[Arindam][a] -选题：[lkxed][b] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]: https://www.debugpoint.com/author/admin1/ -[b]: https://github.com/lkxed -[1]: https://www.debugpoint.com/wp-content/uploads/2021/03/Snap-size-before-cleanup.jpg -[2]: https://www.debugpoint.com/wp-content/uploads/2021/03/Files-under-snaps-directory.jpg -[3]: https://www.debugpoint.com/wp-content/uploads/2021/03/snap-list-all.jpg -[4]: https://superuser.com/a/1330590 -[5]: https://www.debugpoint.com/wp-content/uploads/2021/03/Executing-the-script.jpg -[6]: https://www.debugpoint.com/wp-content/uploads/2021/03/Snaps-size-after-cleanup.jpg -[7]: https://www.debugpoint.com/2018/07/4-simple-steps-clean-ubuntu-system-linux/ -[8]: https://www.debugpoint.com/clean-up-flatpak/ diff --git a/translated/tech/20220716 How to Clean Up Snap Versions to Free Up Disk Space.md b/translated/tech/20220716 How to Clean Up Snap Versions to Free Up Disk Space.md new file mode 100644 index 0000000000..14c4dca432 --- /dev/null +++ b/translated/tech/20220716 How to Clean Up Snap Versions to Free Up Disk Space.md @@ -0,0 +1,105 @@ +[#]: subject: "How to Clean Up Snap Versions to Free Up Disk Space" +[#]: via: "https://www.debugpoint.com/clean-up-snap/" +[#]: author: "Arindam https://www.debugpoint.com/author/admin1/" +[#]: collector: "lkxed" +[#]: translator: "geekpi" +[#]: reviewer: " " +[#]: publisher: " " +[#]: url: " " + +如何清理 Snap 版本以释放磁盘空间 +====== +这个带有脚本的快速指南有助于清理旧的 snap 版本并释放 Ubuntu 系统中的一些磁盘空间。 + +我的 Ubuntu 测试系统中出现磁盘空间不足。因此，我通过 GNOME 的磁盘使用分析器进行调查，以找出哪个软件包正在消耗宝贵的 SSD 空间。除了通常的缓存和主目录，令我惊讶的是，我发现 Snap 和 Flatpak 消耗了大量的存储空间。 + +![Snap size – before cleanup][1] + +尽管如此，我始终坚持一个规则：除非必要，否则不要使用 Snap 或 Flatpak。这主要是因为它们的安装尺寸和其他问题。我更喜欢原生 deb 和 rpm 包。多年来，我在这个测试系统中安装和移除了一定数量的 Snap 包。 + +卸载后出现问题。Snap 在系统中保留了一些残留文件，一般用户不知道。 + +所以我打开了 Snap 文件夹 `/var/lib/snapd/snaps`，发现 Snap 正在跟踪以前安装/卸载的软件包的旧版本。 + +例如，在下图中，你可以看到 GNOME 3.28、3.34 和 Wine 这些都被删除了。但他们还在那里。这是因为 Snap 设计在正确卸载后保留已卸载软件包的版本。 + +![Files under snaps directory][2] + +或者，你可以在终端中使用： + +``` +snap list --all +``` + +![snap list all][3] + +对于保留的多个版本，默认值为 3。这意味着 Snap 会保留每个软件包的 3 个旧版本，包括活动版本。如果你对磁盘空间没有限制，这是可以的。 + +但是对于服务器和其他场景，这很容易遇到成本问题，消耗你的磁盘空间。 + +但是，你可以使用以下命令轻松修改计数。该值可以在 2 到 20 之间。 + +``` +sudo snap set system refresh.retain=2 +``` + +### 清理 Snap 版本 + +在 SuperUser 的一篇文章中，Canonical 的前工程经理 Popey [提供了一个简单的脚本][4]可以清理旧的 Snap 版本并保留最新版本。 + +这是我们将用来清理 Snap 的脚本。 + +``` +#!/bin/bash + #Removes old revisions of snaps + #CLOSE ALL SNAPS BEFORE RUNNING THIS + set -eu + LANG=en_US.UTF-8 snap list --all | awk '/disabled/{print $1, $3}' | + while read snapname revision; do + snap remove "$snapname" --revision="$revision" + done +``` + +将上述脚本以 .sh 格式保存在目录中（例如 `clean_snap.sh`），赋予其可执行权限并运行。 + +``` +chmod +x clean_snap.sh +``` + +当我运行脚本时，它减少了很多磁盘空间。该脚本还将显示要删除的包的名称。 + +![Executing the script][5] + +![Snaps size after cleanup][6] + +### 结束语 + +关于 Snap 的设计效率如何，人们总是争论不休。许多人说，它的设计是坏的，是臃肿的，且消耗系统资源。该论点的某些部分是正确的，我不会否认。如果正确实施和增强，沙盒应用的整个概念就很棒。我相信，与 Snap 相比，Flatpak 做得更好。 + +也就是说，我希望这可以帮助你清理一些磁盘空间。尽管它在 Ubuntu 中进行了测试，但它应该适用于所有支持 Snap 的 Linux 发行版。 + +此外，请查看我们关于[如何清理 Ubuntu][7] 的指南以及其他步骤。 + +最后，如果你正在寻找清理 **Flatpak** 应用，请参阅[这个指南][8]。 + +-------------------------------------------------------------------------------- + +via: https://www.debugpoint.com/clean-up-snap/ + +作者：[Arindam][a] +选题：[lkxed][b] +译者：[geekpi](https://github.com/geekpi) +校对：[校对者ID](https://github.com/校对者ID) + +本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 + +[a]: https://www.debugpoint.com/author/admin1/ +[b]: https://github.com/lkxed +[1]: https://www.debugpoint.com/wp-content/uploads/2021/03/Snap-size-before-cleanup.jpg +[2]: https://www.debugpoint.com/wp-content/uploads/2021/03/Files-under-snaps-directory.jpg +[3]: https://www.debugpoint.com/wp-content/uploads/2021/03/snap-list-all.jpg +[4]: https://superuser.com/a/1330590 +[5]: https://www.debugpoint.com/wp-content/uploads/2021/03/Executing-the-script.jpg +[6]: https://www.debugpoint.com/wp-content/uploads/2021/03/Snaps-size-after-cleanup.jpg +[7]: https://www.debugpoint.com/2018/07/4-simple-steps-clean-ubuntu-system-linux/ +[8]: https://www.debugpoint.com/clean-up-flatpak/
