@Zanna Capistrano itself seems like it may be on-topic -- if this were a question about deploying and automating a server and the OP were using Perl or Python I would guess we would accept it. The question is also on-topic on SO but it obviously can't be migrated there anymore, plus we don't migrate unless something is actually off-topic (or the OP requests it). The answer looks like it should work but I don't want to upvote, at least as written, for two reasons.

Actually, never mind.

I was going to say, if the remote system is Ubuntu then sh isn't Bash, so that should be fixed, and also that there is probably some better way to read the remote system's environment.

But the method shown in the answer is reliable and works, while the method in the question should not be used even with systems where it does (seem to) work, because it greps for the variable name everywhere in the VAR=val line, and thus will return results for variables whose names or even values contain the name of the desired variable.

So, is it possible to edit and upvote?

Eliah Kagan

Well in spite of all the quotes in it, their answer doesn't quote the variable expansion in the shell command passed as an operand to sh -c. It is probably reasonable to expand the answer to add a corrected version, or perhaps even to correct the code already in it, but I'm posting an answer. They can just use the printenv command.

even better

I've posted the answer.

@Zanna I don't think that's a programming question. I think by "compile" they mean "put together," not "translate from source code to executable form." I think by MIB they mean the data, not software that uses it.

Management information base

A management information base (MIB) is a database used for managing the entities in a communication network. Most often associated with the Simple Network Management Protocol (SNMP), the term is also used more generically in contexts such as in OSI/ISO Network management model. While intended to refer to the complete collection of management information available on an entity, it is often used to refer to a particular subset, more correctly referred to as MIB-module. Objects in the MIB are defined using a subset of Abstract Syntax Notation One (ASN.1) called "Structure of Management Information...

@Zanna What's happened? Has the new top bar been rolled out to more users?

@EliahKagan -_-

@EliahKagan thanks! :)

Only one of the answers to this question interprets the question correctly. Two others are based on the idea that that OP wants to upgrade directly from 12.04 to 16.04, which is actually what they want to avoid.

applies votes

if I cast three more downvotes my reputation will be a palindrome

(^-- not a recommended approach to site moderation)

Eliah Kagan

Then you should do that immediately.

Zanna

hahaha

Eliah Kagan

The real question is why the system even allows rep to be anything that is not a palindrome.

edwinksl

better do it soon else i will upvote you

Eliah Kagan

So this question still needs one last close vote.

done

Eliah Kagan

Thanks!

Zanna

@EliahKagan I know, so unsatisfying

Eliah Kagan

@Zanna So should the answers that are answering a different question be edited? What they are saying is at least related. The question is asking how to avoid something, and they are saying there's no way to do that thing...

Or deleted?

Zanna

I think they missed the point of the question, so they are flaggable

Eliah Kagan

Darn it I should've pointed them out to jrg when he was just in here.

Zanna

12:40

oh well

Eliah Kagan

Is this post an attempt to answer the question by suggesting a hardware-based workaround, or is it an attempt to ask a new queston? Either way, the first review comment saying it should be a comment can be flagged.

@Zanna So I am thinking at least one of them is not flaggable.

That one says to use -c to check, and also that it never skips releases, so couldn't it just be edited into shape?

Zanna

@EliahKagan I skipped it in review, because I think it is suggesting a hardware-based workaround, but I was unwilling to click looks OK since it's quite uninformative about how to apply it etc

@EliahKagan like that?

the other answer also says how to upgrade to 14.04, maybe it's not really assuming that they want to upgrade to 16.04

in fact I think it isn't

I undid my downvotes

Eliah Kagan

12:56

Is it worth custom mod flagging this post to suggest it be converted to a comment?

Zanna

yeah, it could be useful

oops gotta go to work \o

Eliah Kagan

I had actually already raised an NAA flag on it. So the system won't let me custom flag it. @edwinksl if you think such a flag should be raised, you could do so. If not, I won't sweat it. (Please only do that if you would've flagged it for that anyway.)
