我啟動了 Tails 2.4 並收到以下訊息：
檢查升級時出錯
在終端機中手動執行升級會出現錯誤：

如何在不完全手動重新安裝的情況下升級？
答案1
問題出在證書上：
Could not download 'https://tails.boum.org/upgrade/v1/Tails/2.4/i386/stable/upgrades.yml',
request failed (Peer certificate cannot be authenticated with given CA certificates):
server certificate verification failed. CAfile: /usr/local/etc/ssl/certs/tails.boum.org-CA.pem
https://tails.boum.org切換到 Let's Encrypt 憑證授權機構，並且這些新憑證在以下版本中遺失2.7。
您可以透過下載「讓我們加密憑證」來修復它：
- 去https://letsencrypt.org/certificates/
- 打開其中之一積極的中級證書 ->Let's Encrypt Authority X3（IdenTrust 交叉簽名）
- 打開
tails.boum.org-CA.pem並使用讓我們加密證書覆蓋其內容。
sudo nano /usr/local/etc/ssl/certs/tails.boum.org-CA.pem （您需要先設定管理密碼）
然後重新運行tails-upgrade-frontend-wrapper。
重複此動作直至安裝 Tails 2.7。

當您（或其他人）擁有更新的尾巴時，您可以從較新的運行尾巴升級您的棍子。只需使用 Tails 安裝程式即可。它不會從網路下載tails，而是使用正在執行的tails。
提示：僅在 Tails 安裝程式啟動後才插入舊的 tails。
