chromium-browser-dbg missing for 52.x

[Chris West]

chromium-browser has reached version 52.0.2743.116-0ubuntu0.16.04.1.1250, but the associated debug packages
in chromium-browser-dbg are still at 51.0.2704.79-0ubuntu0.16.04.1.1242. These are uninstallable, as they depend on "=" the same chromium-browser version, which is no longer in the archive.

This is a bug, in that there should be -dbg transition packages. Debug symbols are now provided in chromium-browser-dbgsym .

Add the debug sub-repo to your APT source. Note the end of this line:

deb http://us.archive.ubuntu.com/ubuntu/ yakkety universe universe/debug

[Chris West (faux)]

I don't seem to be able to get that to work, either. My aim here was to install the symbols on Xenial, so I can file a reasonable bug report for a piece of chromium behaviour.

Neither the xenial, nor yakkety, "/debug" package lists seem to have chromium-browser-dbg* in. Nor do any of the lists on ddebs.ubuntu.com, although it does have the package I am after (I believe)! I guess I'll just install it without checking a signature.

http://ddebs.ubuntu.com/pool/universe/c/chromium-browser/chromium-browser-dbgsym_52.0.2743.116-0ubuntu0.16.04.1.1250_amd64.ddeb

[Chad Miller (cmiller)]

I was wrong that there should be dbg transition packages.

"When transitioning to the new system, just drop the -dbg package."

https://wiki.debian.org/DebugPackage

So, install dbgsym manually.
