[Dmytro] There is outdated version Eclipse 7.76.0 in main branches, while 7.77.0 is expected after release of 7.76.0:

• 7.76.0-SNAPSHOT in che-server
• 7.76.0-next in che-dashboard
• 7.76.0-next in che-devfile-registry
• 7.76.0-next in eclipse/che

At the same time version is correct in the next repos:

• 7.77.0-SNAPSHOT in che-plugin-registry
• 7.77.0-next in che-code

Describe the solution you'd like

[Nick] Recently, GH action runners were updated to no longer include hub already installed, so GH actions that use hub need to explictly install it. For example, eclipse-che/che-devfile-registry#793

Additional context

It was che-bot who created MR with update to next in Eclipse Che repo: #22568 (comment)

7.76.0 in che-operator

That's ok - the latest stable version is printed.

@tolusha : thanks for the notice.

Better solution: devfile/devworkspace-operator@9fce312

The hub CLI has been removed from the Ubuntu 20.04 runner and is
intended to be replaced with the gh CLI. This commit adapts the
previous hub command to open a PR into a gh command that does the same.

-    lastCommitComment="$(git log -1 --pretty=%B)"
-    $DRY_RUN hub pull-request -f -m "${lastCommitComment}" -b "${CURRENT_BRANCH}" -h "${PR_BRANCH}"
+    $DRY_RUN gh pr create -f -B "${CURRENT_BRANCH}" -H "${PR_BRANCH}"

Next release will ensure that all versions are properly updated, closing this issue for now
