【问题描述】：

我是一个使用 openSUSE 的新手。 最近执行zypper update，发现yast2 UI客户端无法启动。在/var/log/YaST2/y2log可以看到登录：

我已经报告了错误https://bugzilla.suse.com/show_bug.cgi?id=1167315，但一周没有得到答复。

我该如何解决这个问题。谢谢。

【参考方案1】：

在 Stefan 的帮助下，我的问题得到了解决。

原因是我最近安装的输入法软件（Leap 15.1）版本与系统版本（Leap 15.0）冲突。

我的解决方法如下：

(1) 移除 M17N repo(Leap 15.1)

sudo zypper rr 1  ## 1 is the index number of M17N after `sudo zypper lr`

(2) 添加 M17N repo(Leap 15.0)

sudo zypper ar -f https://download.opensuse.org/repositories/home:/MargueriteSu:/branches:/M17N/openSUSE_Leap_15.0/home:MargueriteSu:branches:M17N.repo

(3) 更新仓库

sudo zypper update

(4)卸载搜狗拼音/yast2(包括kde_yast和yast2_basis)/fast_gettext

sudo zypper remove sogou-pinyin
sudo zypper remove yast2-ruby-bindings
sudo zypper remove ruby2.5-rubygem-fast_gettext
sudo gem uninstall fast_gettext

(5) 重新安装 yast2

sudo zypper install patterns-kde-kde_yast
sudo zypper install patterns-yast-yast2_basis

(6)重新安装搜狗拼音

sudo zypper install sogou-pinyin

我的 yast2 重生。
