@vikashg did you do pip update? Most likely not, based on this error log entry, "Could not find a version that satisfies the requirement holoscan~=2.0 (from versions: 0.0.0.post1, 0.4.0, 0.4.1, 0.5.0, 0.5.1, 0.6.0); Holoscan 1.0 was released early in the year and it did not get list by your pip.

[vikashg]

So, I did the following

pip install --upgrade pip

The result is the same. I believe you want me to update the pip package index ?

I have holoscan 0.6.0 installed. I tried

pip install --upgrade holoscan

But it didn't yield anything. I have pip 24.0 and python 3.10

@vikashg I am closing this issue as it has been answered in the referenced issue. MONAI Deploy App SDK depends on Holoscan SDK, and since v1.0, Ubuntu 22.04 is required as it is by Holoscan v1.0+ to ensure glibc >= 2.35.
