I read in another topic that the only supported upgrade path is from one
minor version to the next. I have backends that were last used with s3ql
2.15, which are no longer usable because Ubuntu's s3ql and llfuse packages
are incompatible (I started another topic about this and the suggestion was
to switch one or both versions, which I can't see a way to do in Ubuntu).
I'm trying to go back and build each old version of s3ql from source
starting from 2.15, but the tests failed on 2.15 and 2.16 so I'm at a
standstill already. Both failures appear to be to do with llfuse, which I
have built and installed the most recent version of successfully (1.2).
I'm just following the most recent install docs, for 2.21, which state
required versions of dependencies, but I don't know what these docs will
have said about how to build older versions. Are these docs stored
somewhere? If not, can you tell me which versions of llfuse I need for each
release? And of course, how to build each of those and what their
dependencies were :)
For reference, the 2.15 test failure was this:
