I found the message that it’s recommended do instaöll this library because today there shall be a update to the linux version. But I just get this error message when I try to do it...
The message I mean is [this one](https://help.roonlabs.com/portal/en/kb/articles/linux-performance-improvements#Whats_happening).
And the error message is: »E: Unable to locate package libicu66«
What Linux are you trying this on? The instructions are for older versions and current versions don’t have a libicu66 anymore as this is a specific version of the library. Current Ubuntu, for instance, has libicu72 or something like that. Normally, one doesn’t install a specific library version anyway; the instructions seem strange.
There might be a virtual package that always references the latest libicu. On Ubuntu, try:
apt install libicu
If this doesn’t work, search for the package with:
Aha. The text is supposedly 11 months old, so it seemed plausible to me that the 3rd of November it talks about is today. But if that’s not the case, that’s fine. Thank you very much. Then I’ll just wait and see what happens. And if the server suddenly stops working, the subscription is quickly cancelled…
Ubuntu 20.04 was released in April 2020. It is just another example of an outdated documentation page. The transition of Roon to .NET on Linux happened years ago.
However, any libicu version will be fine, whatever version your Linux installation has. That’s why I said to search for libicu.
