Print this reportUpdates of OS packages on clients and serversSome OS packages were updated on client workstations, gateway server and SummaryPages server. This update contains only common system packages. CDS tools weren't affected.
Note: Because k1ctr14 at IYV was unreachable, it wasn't updated. Entering the mine is needed for recovering it, but not today. It's not urgent, so I'll do it when I'm doing another mine work.

I missed the fact that the configuration of ssh client is shared between k1ctr/k1mon and k1script. As the result, HWP didn't work well. Mismatch between EPICS value and actual position of HWP didn't occur thanks to the strict error handling of the HWP script.
I fixed the configuration of ssh client and HWP is now available properly.
----- The configuration file which works well on k1ctr/k1mon is also used on k1script. Because k1script1 is running as older OS than ones on k1ctr/k1mon, algorithms mismatch was occurred between installed OpenSSH on k1script and the configuration file. For fixing this issue, I removed sntrup761x25519 from KexAlgorithms.
There is no necessity to use that algorithm also on k1ctr/k1mon, so this response is sufficient. But to avoid similar issue in future, it might be better to separate an origin of deployed configuration between k1ctr/k1mon and k1script.

Print this reportThough a server-side problem due to the old version of OS was fixed in the previous work (klog#35101), a client-side problem remained. Today, it appeared when HWP was operated via guardian and I fixed it again.
