RE: [uml-user] Cannot run UML 2.4.26 while 2.4.24 is working fine, with exactly same configuration, fs, ...

[Chris H. <cha...@mv...>]

Don't really know, but looks like you should check your root file system.
It appears to have some corruptions related at least to networking and maybe
other issues.

I'd start by looking at this error, and seeing if you can resolve it in your
File System.
etc/network/if-up.d/rezo is a broken symbolic link
