For YUM (RHEL) I can specify repository with HTTPS link to key file, like /etc/yum.repo.d/elastic-7.x.repo:

[elastic-7.x]
baseurl = https://artifacts.elastic.co/packages/7.x/yum
gpgcheck = 1
gpgkey = https://artifacts.elastic.co/GPG-KEY-elasticsearch
name = Elasticsearch repository for 7.x packages

In case of Debian I have to download a key file first:

sudo curl -o /usr/share/keyrings/elastic.asc https://artifacts.elastic.co/GPG-KEY-elasticsearch

and than register that file by the attribute signed-by:

deb [signed-by=/usr/share/keyrings/elastic.asc arch=amd64] https://artifacts.elastic.co/packages/7.x/apt stable main

Can I specify the signing key by HTTPS URL?

This way I avoid updating keys when they rot.

Do I properly understand that it is not possible to run /etc/cron.daily/my from arbitrary user, it will be run only from root according to /etc/crontab?

Can I drop root privilege to specific user in my cron scrip instead?

It is better to place cron job into /etc/cron.d? Like:

$ cat /etc/cron.d/my
5 0 * * *  user  test -x /usr/bin/my && /usr/bin/my -cfg /etc/my.cfg

Ubuntu uses packages from Debian (it is based on Debian).

I wonder what extra packages or package classes are added to Ubuntu?

I expect to see some proprietary software, some extra office software, some build-in adware...

Let's compare with latest stable releases. But it doesn't hurt if you add some important historical notes too...

I am talking only about official upstream package repositories. No need to talk about PPA.

I am not interested in branding or styling or release cycle or support or whatever discussed at How is Ubuntu different from Debian? difference. Only about the difference in packages and that link doesn't tell anything related they I haven't mentioned in my question.

I already use HOME=c:\home as my home directory (for Cygwin).

How can I point WSL to that directory?

I edited /etc/passwd file replacing home dir to /mnt/c/home. With bash -i ~/.bashrc settings are picked up.

Is it correct to move home directory outside of WSL world?

Evince places left sidebar widget which placeholder for index and thumbnails (they call it Side Pane). It can be easy closed by clicking on X GUI button or F9 keyboard button and this changes saved across document opening.

Index is useful feature, but thumbnails eat space and slowdown scrolling dramatically.

Is it possible hide side pane by default? Or better only in case when there are no index?
