Ubuntu 12.04: apt-get can't parse repository url if username contains @ ('at' sign)

What is the output of:

lsb_release -a; uname -a; cat -n /etc/apt/sources.list.d/myrepo.list

Thanks

$ lsb_release -a

E: Some index files failed to download. They have been ignored, or old ones used instead.

For security reasons, I prefer not to disclose the URL. But if I use a username without '@' (at sign) everything works fine.

What if you change the line to:

deb https://domain.com/xyz precise non-free

Is it OK?

According to the documentation replacing the @ sign by %40 should make it work, but you write that it doesn't.

If you change to

 deb https://FOO%40BAR:<email address hidden>/xyz precise

do you get the identical error message, or something different?

Exactly the same problem with %40:

$ cat -n /etc/apt/sources.list.d/myrepo.list
     1 deb https://FOO%40BAR:<email address hidden>/xyz precise non-free
$ apt-get update
...
W: Failed to fetch https://domain.com/xyz/dists/precise/non-free/binary-amd64/Packages Couldn't resolve host 'BAR'

W: Failed to fetch https://domain.com/xyz/dists/precise/non-free/binary-i386/Packages Couldn't resolve host 'BAR'

E: Some index files failed to download. They have been ignored, or old ones used instead.

If the username doesn't contain '@', everything works fine. Even for this fake URI, there is a different error message:

$ cat -n /etc/apt/sources.list.d/myrepo.list
     1 deb https://FOOBAR:<email address hidden>/xyz precise non-free
$ apt-get update
...
Err https://domain.com precise/non-free amd64 Packages

W: Failed to fetch https://domain.com/xyz/dists/precise/non-free/binary-i386/Packages

E: Some index files failed to download. They have been ignored, or old ones used instead.

Also, there is no problem on Ubuntu 14.04.

I understand that you do not want to reveal the real usernames and domain names (and of course the password).

But due to editing that information, it is not clear to me whether the error message with @ sign is the same as the one that you get for %40 or not.

Is it
Couldn't resolve host 'BAR:<email address hidden>'
or
Couldn't resolve host 'BAR'
?

That's interesting. The error message depends on the password:

deb https://FOO@BAR:<email address hidden>/xyz precise non-free --> Couldn't resolve host 'BAR:<email address hidden>'
deb https://FOO@BAR:<email address hidden>/xyz precise non-free --> Couldn't resolve host 'BAR'

The error message depends on the first character of the password: a digit or a letter.

deb https://FOO%40BAR:<email address hidden>/xyz precise non-free --> Couldn't resolve host 'BAR:<email address hidden>'
deb https://FOO%40BAR:<email address hidden>/xyz precise non-free --> Couldn't resolve host 'BAR'

I searched through the change history of apt, but did not find any reference to such problem between the versions for precise and trusty. (Logic regarding escaping like %40 was there already before 0.8.16~exp12).

I suggest you create a bug report.

Thanks. I created https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1558484.
