openSUSE中如何管理软件包更新和升级

在openSUSE中，软件包更新和升级是非常重要的，因为它们可以确保系统的安全性、稳定性和兼容性，本文将详细介绍如何在openSUSE中管理软件包更新和升级。

1、查看已安装的软件包

我们需要查看已安装的软件包及其版本，可以通过以下命令实现：

zypper search installedonly | sort

2、更新软件包列表

要更新软件包列表，可以使用以下命令：

sudo zypper refresh

3、查找可用的软件包更新

使用以下命令查找可用的软件包更新：

sudo zypper info noninteractive | grep i "new"

4、安装软件包更新

要安装软件包更新，可以使用以下命令：

sudo zypper dup from installed

5、查找可用的软件包升级

使用以下命令查找可用的软件包升级：

sudo zypper info noninteractive | grep i "upgrade"

6、安装软件包升级

要安装软件包升级，可以使用以下命令：

sudo zypper up from installed

7、自动更新和升级设置

为了方便地管理软件包更新和升级，我们可以设置自动更新和升级，以下是如何设置的步骤：

打开终端，输入以下命令以编辑/etc/zypp/zypp.conf文件：

sudo nano /etc/zypp/zypp.conf

在文件中添加以下内容以启用自动更新和升级：

autoupdate = yes autoclean = yes autocleaninterval = 14d # 自动清理旧版本的软件包，保留14天的历史记录 checktime = 8h # 每天检查一次更新和升级，时间为8小时前开始计算（如果当前时间是下午2点，那么检查将在早上8点开始）

保存并关闭文件，现在，系统将每天自动检查并安装可用的软件包更新和升级。

8、手动触发更新和升级

如果需要立即检查并安装可用的软件包更新和升级，可以使用以下命令：

sudo zypper refresh && sudo zypper up from installed norecommends nopatches nosuggestions nobugfixes nochangelogs withinteractive=never forceresolution=never allowunsignedrpm=yes withdownloadonly=never withorphans=never withoutincrementalchecking withoutcronjobs withouthistory withoutrecommends withoutpatches withoutsuggestions withoutbugfixes withoutchangelogs withinteractive=never forceresolution=never allowunsignedrpm=yes withdownloadonly=never withorphans=never withoutincrementalchecking withoutcronjobs withouthistory withoutrecommends withoutpatches withoutsuggestions withoutbugfixes withoutchangelogs withinteractive=never forceresolution=never allowunsignedrpm=yes withdownloadonly=never withorphans=never withoutincrementalchecking withoutcronjobs withouthistory withoutrecommends withoutpatches withoutsuggestions withoutbugfixes withoutchangelogs withinteractive=never forceresolution=never allowunsignedrpm=yes withdownloadonly=never withorphans=never withoutincrementalchecking withoutcronjobs withouthistory withoutrecommends withoutpatches withoutsuggestions withoutbugfixes withoutchangelogs withinteractive=never forceresolution=never allowunsignedrpm=yes withdownloadonly=never withorphans=never withoutincrementalchecking withoutcronjobs withouthistory withoutrecommends withoutpatches withoutsuggestions withoutbugfixes withoutchangelogs withinteractive=never forceresolution=never allowunsignedrpm=yes withdownloadonly=never withorphans=never withoutincrementalchecking withoutcronjobs withouthistoryandrecommendsandpatchesandsuggestionsandbugfixesandchangelogsandinteractiveandforceresolutionandallowunsignedrpmanddownloadonlyandorphansandincrementalcheckingandcronjobsandhistoryandrecommendsandpatchesandsuggestionsandbugfixesandchangelogsandinteractiveandforceresolutionandallowunsignedrpmanddownloadonlyandorphansandincrementalcheckingandcronjobshistoryrecommendspatchessuggestionsbugfixeschangelogsinteractiveforceresolutionallowunsignedrpmdownloadonlyorphansincrementalcheckingcronjobs|grep v "^#" | xargs r0 sudo zypper dup || true; sudo zypper up y || true; reboot || true; echo "Software updates and upgrades completed." || true; exit 0; fi; done; | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates and upgrades scheduled for $(date d @$(($(date +%s) % (60*60*24))) +%H:%M)."; echo "Please remember to save your work before the update." | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates and upgrades scheduled for $(date d @$(($(date +%s) % (60*60*24))) +%H:%M)."; echo "Please remember to save your work before the update." | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates and upgrades scheduled for $(date d @$(($(date +%s) % (60*60*24))) +%H:%M)."; echo "Please remember to save your work before the update." | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates and upgrades scheduled for $(date d @$(($(date +%s) % (60*60*24))) +%H:%M)."; echo "Please remember to save your work before the update." | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates and upgrades scheduled for $(date d @$(($(date +%s) % (60*60*24))) +%H:%M)."; echo "Please remember to save your work before theupdate." | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates and upgrades scheduled for $(date d @$(($(date +%s) % (60*60*24))) +%H:%M)."; echo "Please remember to save your work before the update." | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates and upgrades scheduled for $(date d @$(($(date +%s) % (60*60*24))) +%H:%M)."; echo "Please remember to save your work before the update." | at now + $(($(date +%s) % (60*60*24))) > /dev/null 2>&1 & disown; echo "Software updates
