Re: Apparent timeouts

Hi Tõivo,

In view of what you said I would like to upgrade my unison from the 
2.51.5 ocaml 4.13.1 which comes with my Ubuntu 22.04 LTS to 2.52 or 
2.53. I understand that either of the latter will be backward compatible 
with 2.51 and 2.48 (and thus with Ubuntu 18.04 LTS which I have on a 
legacy machine).

I certainly do not want to get into compiling - not worth the learning 
effort for me.

The documentation on the CI binaries says that their Ubuntu is "probably 
20.04, and will likely work on other x86-64 machines with compatible 
dependencies". Does that mean that there is some chance that the 
binaries will not run on 22.04?

The Migration Guide 
<https://urldefense.com/v3/__https://github.com/bcpierce00/unison/wiki/2.52-Migration-Guide__;!!IBzWLUs!TwHb4MUqObnZNzy9Dg7QPIEIsRwP85BttRIoRhHCE6aUQ0sZw511Ffhq9-t-A4TxEtyNFwGFjf5M8Hcgqc2oHeKbPmc$ > says 
that the archives will have to be rebuilt if the ocaml version differs 
from the one for the previously installed unison version. This issue is 
not really critical for me, as long as the final result will be backward 
compatible, but would be nice to know in advance the ocaml version of 
the selected binary.

I see the page Installing binaries built by the CI process 
<https://urldefense.com/v3/__https://github.com/bcpierce00/unison/wiki/CI-Binary-instructions__;!!IBzWLUs!TwHb4MUqObnZNzy9Dg7QPIEIsRwP85BttRIoRhHCE6aUQ0sZw511Ffhq9-t-A4TxEtyNFwGFjf5M8Hcgqc2oClptfV8$ > but I 
can't see where to actually get the CI binaries, or to see with what 
ocaml version they were compiled (would be nice for you to add this 
link, unless it is there and I missed it).

If I upgrade should I first uninstall the prepackaged unison? Will the 
new unison version show up in the Syaptic package manager or do I just 
have to remember that it is there? I assume that if ever there were a 
problem I could simply reinstall the prepackaged version (that it won't 
disappear from the Synaptic package manager?

If I want to upgrade with minimal risk (with the idea of having a stable 
installation for several years), should I try 2.52 rather than 2.53, or 
would it be best to go immediately for 2.53?

Thanks and best regards,

     John
