Problem installing issue

Hello everyone, I have the Julia version 1.8.5 installed and I successfully add a kernel to Jupiter notebook, and I did the same thing to version 1.7.2. Now I need to add the kernel of Julia 1.5.3, when I add package IJulia, it gives the following error:

ERROR: The following package names could not be resolved:

  • IJulia (not found in project, manifest or registry)

Anyone knows what is going on here?

I’m going to guess that Julia 1.5 is missing a copy of the general registry that it can understand. You might need to update the registry explicitly.

I do want to point out that all the versions you pointed out are unsupported. Currently only Julia 1.6.7 and Julia 1.10.3 are supported. Given the trend, perhaps you should strongly consider sticking to the LTS version.
