@alcaliva , @alibuild : it's not clear to me what's the error for the macOS-arm test. Could the test be rerun?

[vkucera]

@arossi81 @alcaliva Please do not ignore the failing tests.

[arossi81]

Hi @vkucera , what do you mean? The required macOS-arm test is failing w/o a reason, no log.

Hi @vkucera , what do you mean? The required macOS-arm test is failing w/o a reason, no log.

Hi @arossi81 , I mean the other failing tests: MegaLinter and O2 linter.

[arossi81]

@vkucera , @alcaliva
while waiting that the pull requests can be merged again I fixed most of the Linter and MegaLinter issues. I would prefer to not touch the remaining ones. @alcaliva , I need again your approval, thanks!

[vkucera]

Thanks @arossi81 for the fixes! The remaining 2 errors are trivial to fix but I understand if there is an urgency in merging the PR.
