This version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.2, which can't be reverted.
You may want to back it up before going further.
[NOTE] The 'jobs' option was reset, its value was 71 and its new value will vary according to the current number of cores on your machine. You can restore the fixed value using:
opam option jobs=71 --global

The following actions will be performed:
=== install 5 packages
- install conf-libseccomp 1 [required by solo5]
- install conf-which 1 [required by ocaml-solo5]
- install ocaml-solo5 0.8.5 [required by timeout1-xen, resolve-xen, noop-xen, etc.]
- install ocaml-src 4.14.3 [required by ocaml-solo5]
- install solo5 0.10.1 [required by timeout1-xen, resolve-xen, noop-xen, etc.]
The following system packages will first need to be installed:

<><> Handling external dependencies <><><><><><><><><><><><><><><><><><><><><><>
opam believes some required external dependencies are missing. opam can:
> 1. Run apt-get to install them (may need root/sudo access)
2. Display the recommended apt-get command and wait while you run it manually (e.g. in another terminal)
3. Continue anyway, and, upon success, permanently register that this external dependency is present, but not detectable
4. Abort the installation
