zypper 退出程式碼 106 - 如何修復？

在 SLES11.4 伺服器上想要安裝一個包：

SLES11SERVER:~ # zypper in -f telnet
Retrieving repository 'foobar_common' metadata [\]
File 'repomd.xml' from repository 'foobar_common' is unsigned, continue? [yes/no] (no): yes

SLES11SERVER:~ # echo $?
106
SLES11SERVER:~ #

根據手冊頁：

106 - ZYPPER_EXIT_INF_REPOS_SKIPPED
          Some repository had to be disabled temporarily because it failed to refresh. You should check your
          repository configuration (e.g.  zypper ref -f).

所以我做了一個“zypper ref -f”：

SLES11SERVER:~ # zypper ref -f
...
Retrieving repository 'foobar_common' metadata [/]
File 'repomd.xml' from repository 'foobar_common' is unsigned, continue? [yes/no] (no): yes
Retrieving repository 'foobar_common' metadata [error]

Skipping repository 'foobar_common' because of the above error.

Some of the repositories have not been refreshed because of an error.
SLES11SERVER:~ #

該軟體包已安裝（來自另一個儲存庫，此 foobar_common 未提供它），但在安裝軟體包後，我必須為 zypper 設置退出程式碼 0。

**問：**如何解決 zypper 不會給出退出程式碼 106 的問題？

我試過了：

• 刪除/添加 foobar_common 倉庫，同樣的問題

問題出在儲存庫方面（回購操作團隊的PEBKAC :)）

還有，zypper clean --all有幫助。
