sudo dpkg --install --ignore-depends=libicu72 powershell_7.4.2-1.deb_amd64.deb

Doesn't this lead to problems because the dependent package is missing?

Perhaps a better option would be to create a dummy package that uses the newer version instead...

You're right. At least further use of apt wouldn't really work until I did the cleaning up it told me to do, which uninstalled powershell again (forgot the command).

I don't really know that much about apt/dpkg, so I just perused man dpkg for a way to in some way ignore / override the dependency, and it worked; PowerShell was installed. Although the succes was short-lived, as apt just complained afterwards.

Out of curiosity, how does deb handle the upgrade proces when a "real" new version of libicu72 or libicu74 is available?

And thank you for your solution/workaround :)

libicu74 is already a real version currently used by Noble Numbat. The dummy package libicu72 only redirects everything to this package.

As soon as Powershell is officially released for Noble, it will also use version >=74. The dummy package will then be obsolete. However, it will remain in the system until it is manually uninstalled.
