Packages in main and universe are built in the launchpad build farm, from source. You don't need to ask for verification of this as you can find it yourself. For example, at the time of writing the most recent build of bind uploaded to Ubuntu 20.04 LTS (Focal) is 1:9.16.1-0ubuntu2.5. You can see this via the focal-changes public mailing list.

Don't confuse support and stability. LTS releases offer "stability" in the sense that the software does not change for 5 years, not the sense that it crashes less often. The latter coincidentally does happen to be somewhat true also, but that's due to the large user base discovering and filing bugs. The best way to keep any release of Ubuntu ...

If you install the youtube-dl package from the 20.04 Ubuntu archive, it does not result in any /usr/local/bin/youtube-dl file. So probably you have previously installed youtube-dl in some other way than one of the ways you mention in your question, and that may be the cause of the confusion. If you don't remember how that happened, I would suggest that you ...

From the Debian perspective: all packages are built on our dedicated servers (buildd's). Packages that are not built on the buildd's are not allowed to move into Testing and get into a stable release. Furthermore, every package built since about 2018 includes a .buildinfo file: while this doesn't guarantee reproducible builds, it does enable them. All ...

I had the same issue during an upgrade to Ubuntu 20.04. During the installation of the Chromium snap package, I would see this message: INFO waiting for automatic snapd restart And then the installation process was just doing nothing as that automatic restart never happened. So I unlocked progress in the installation process again by executing the expected ...

There is no "official" development platform or setup for Ubuntu. Use what works best for you. If you name a common programming language or IDE, somebody develops for Linux using it.

I am on Mint 19.3, but this should also work for Ubuntu 18.04, which is what this Mint version is based on. My solution was to specify the version to use specifically when installing: sudo apt-get install llvm-10* The reason to use the glob asterisk here is that some of the related packages are also needed for things to work, so merely installing the base ...

As we see, bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4 doesn't compile correctly for your system. On my system, using the exact same kernel version, bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7 installs correctly. I therefore suggest: mkdir bcmwl && cd bcmwl wget http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30....

So, to answer your 3 questions, No, you don't need to remove the apt-installed clang. Just keep it where it is in /usr/bin/clang. If you download and install clang as a user, you probably have the option to put it in your home directory. If it's installed in a system-level directory, it would probably go under /usr/local/. For example, /usr/local/bin/. ...
