downloaded .debs have url escape code in name?! [SOLVED]

When I download packages that contain a colon in the version number (e.g., ffmpeg 7:3.2.10-1~deb9u1 or xserver-common 2:1.19.2-1+deb9u2), the downloaded package name contains %3a where I was expecting :.

bruno@thinkpad:~/Desktop$ apt download ffmpeg xserver-common
Get:1 http://gnuser.ddns.net/devuan/merged ascii/main amd64 ffmpeg amd64 7:3.2.10-1~deb9u1 [1,530 kB]
Get:2 http://gnuser.ddns.net/devuan/merged ascii/main amd64 xserver-common all 2:1.19.2-1+deb9u2 [2,059 kB]
Fetched 3,589 kB in 4s (784 kB/s)           
bruno@thinkpad:~/Desktop$ ls
ffmpeg_7%3a3.2.10-1~deb9u1_amd64.deb
xserver-common_2%3a1.19.2-1+deb9u2_all.deb

Using apt-get download instead of apt download makes no difference.

Is this expected behavior, an upstream bug, or symptom of some misconfiguration on my system? (Internet searches have come up dry.)

ffmpeg_7%3a3.2.12-1~deb9u1_amd64.deb
xserver-common_2%3a1.19.2-1+deb9u2_all.deb

It does not screw up Debian.
So probably its not a problem in Devuan too.

They look like that in /var/cache/apt/archives, too. I always assumed it was normal.

Re: downloaded .debs have url escape code in name?! [SOLVED]

Thank you, yeti and fsmithred. Good to know this is just how it is. I thought something in my /etc/apt/apt.conf.d/ or /etc/apt/preferences.d/ was broken.

Then my guess then is that it is either this way by design (for some reason unknown to me) or else it's a minor bug that's only cosmetic.

At any rate, I booted an old Debian 8 partition, downloaded ffmpeg, installed it, and checked the installed version. There are no url escape codes in the version that apt reports being installed. (I guess this is not surprising since apt gets version number from package's /DEBIAN/control file and not from the name of the .deb file.) No harm, no foul.

bruno@thinkpad8:~/Desktop$ apt-get download ffmpeg
Get:1 http://ftp.us.debian.org/debian/ jessie-backports/main ffmpeg amd64 7:3.2.10-1~deb9u1~bpo8+1 [1,535 kB]
Fetched 1,535 kB in 0s (1,537 kB/s)

bruno@thinkpad8:~/Desktop$ ls
ffmpeg_7%3a3.2.10-1~deb9u1~bpo8+1_amd64.deb # note the '%3a'

bruno@thinkpad8:~/Desktop$ sudo gdebi ./ffmpeg_7%3a3.2.10-1~deb9u1~bpo8+1_amd64.deb 
# installation proceeds normally

bruno@thinkpad8:~/Desktop$ apt list --installed ffmpeg
Listing... Done
ffmpeg/jessie-backports,now 7:3.2.10-1~deb9u1~bpo8+1 amd64 [installed] # note the ':'

Sorry for the noise, but when I first noticed this it was completely unexpected.
