Windows10の更新でOpenSSHが逝った

今更ながら、Raser Blade Stealth 2018にもWindows10 ver1809の更新が来てたようだった。

何の気なしに更新してみたところ、更新自体はすぐに終わってあっさりいったなと思っていたのだが、terminalを立ち上げると...

TL;DR

Windows10 ver1809のOpenSSHは既知のバグがあるのでOpenSSH Portableを入れ直そう。

まずSSH Agentのサービスが無効になってた

Get-Process : Cannot find a process with the name "ssh-agent". Verify the process name and call the cmdlet again.
At C:\Users\takatoshi\OneDrive\Documents\PowerShell\Microsoft.PowerShell_profile.ps1:40 char:8
+ if (! (Get-Process -Name 'ssh-agent')) {
+        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : ObjectNotFound: (ssh-agent:String) [Get-Process], ProcessCommandException
+ FullyQualifiedErrorId : NoProcessFoundForGivenName,Microsoft.PowerShell.Commands.GetProcessCommand

PowerShellのprofileでssh-agentのプロセスの存在を確認するようにしてたのだけど、Windowsの更新でサービスの自動実行が無効になってたようなのでこのエラーが...とりあえず今回は手動で自動実行するように変えて終わった。

あとどういうわけかわからないが、PC起動時のサービスの立ち上がりがめちゃくちゃ遅くなった気がする(体感)。PC起動後にすぐterminalを立ち上げると同じエラーがまだ出るから。根治させるにはprofileをいじらないといけないかな🤔

後述の問題に比べれば、こちらは楽しいアクシデント程度のものだ。

Win10備え付けのOpenSSHに既知のバグが有るとか云々

$ git remote show origin
warning: agent returned different signature type ssh-rsa (expected rsa-sha2-512)
...

↑この警告が常時出るようになった。むかつく💢

直さな...😭と思ってググってみると...

ssh-agent: agent returned different signature type · Issue #1263 · PowerShell/Win32-OpenSSH

これの様子🤔

更に調べると、これマジIssueやなと思わざるを得ない... -> Fixes to ssh-agent issues by manojampalam · Pull Request #366 · PowerShell/openssh-portable

つまりはバグが直ったOpenSSH-Portbale入れないと解決しないってんでFAかな...キレそう❤

Moving from Windows 1809's OpenSSH to OpenSSH Portable

幸いにも同じ障害を解消したブログがあったので助かる🙏

処置する

Moving from Windows 1809's OpenSSH to OpenSSH Portable

この記事にそのまま従えばいける。

Windowsに関わる操作はPowerShell Coreではできないので、PowerShell CoreとWindowsPowerShellを使い分けた(WindowsPowerShellで全部やればいいものを...😅)

Coreでできる範囲から始める。

$ Get-Service -Name ssh-agent | Stop-Service
$ sc.exe delete ssh-agent
[SC] DeleteService SUCCESS

WindowsPowerShellでしかできない範囲

$ Remove-WindowsCapability -Online -Name "OpenSSH.Client~~~~0.0.1.0"


Path          :
Online        : True
RestartNeeded : False



$  Remove-WindowsCapability -Online -Name "OpenSSH.Server~~~~0.0.1.0"


Path          :
Online        : True
RestartNeeded : False

Coreで続きをやる

$ choco install openssh --package-parameters="/SSHAgentFeature"

Chocolatey v0.10.13
2 validations performed. 1 success(es), 1 warning(s), and 0 error(s).

Validation Warnings:
 - A pending system reboot request has been detected, however, this is
   being ignored due to the current Chocolatey configuration.  If you
   want to halt when this occurs, then either set the global feature
   using:
     choco feature enable -name=exitOnRebootDetected
   or pass the option --exit-when-reboot-detected.

環境変数PATHを反映させてから、terminalでwariningが消えたのを確認

振り返り

Windowsのでかい更新の際はちゃんと注意して取り組まなあかんな🤔(めんどい)

あとこれまた既知の別件なのだけど、ver1809だとterminalのemojiの表示が中点とかに化けるので、これもなんとかしたいわ...

Cmder/ConEmuじゃなくてWindows自体の問題みたい。
