this doesn't happen in a clean environment, but it's not clear what dependency is causing openssl to lock at a specific version

These two lines tell you where the dependencies come from. It's most likely your dev version of UnROOT.

that CondaPkg.toml has nothing but the openssl I just added

> cat /home/akako/Documents/github/dotFiles/homedir/.julia/dev/UnROOT/CondaPkg.toml
[deps]
openssl = "=3.3.0"

for completness:

> cat /home/akako/.julia/packages/PythonCall/Nr75f/CondaPkg.toml
[deps.libstdcxx-ng]
version = "<=julia"

[deps.openssl]
version = "<=julia"

[deps.python]
build = "**cpython**"
version = ">=3.8,<4"

[hhaensel]

Could you do a

pkg> st -m

to check for Julia's OpenSSL packages? From you output it looks as if the two version restrictions

libstdcxx-ng[version='>=3.4,<13.0']
openssl[version='>=1.1, <1.1.24']

result from the version = "<=julia" I suspect that your OpenSSL or OpenSSL_jll is at 1.x. In that case you could do a

pkg> st -m --outdated

To check what's restricting your version. Maybe, you just need a package update?

[hhaensel]

It's your XRootD dependency, in particular its dependency of an older version of CxxWrap. You might open an issue and ask the author to support a newer version of CxxWrap.jl.

You can now set JULIA_CONDAPKG_OPENSSL_VERSION=ignore if you'd like to turn off this behaviour. See the README for more info.
