Установка skype на Fedora 33

При установке skype может возникнуть такая вот ошибка:

$ sudo dnf install skypeforlinux-64.rpm
Последняя проверка окончания срока действия метаданных: 0:07:31 назад, Пн 29 мар 2021 09:16:25.
Ошибка: 
 Проблема: conflicting requests
  - nothing provides libatomic1 needed by skypeforlinux-8.69.0.77-1.x86_64
(попробуйте добавить «--skip-broken» для пропуска удаляемых пакетов)

$ sudo dnf install skypeforlinux-64.rpm

Лечится пересборкой rpm пакета.

$ cd ~/
$ wget --trust-server-names https://go.skype.com/skypeforlinux-64.rpm
$ sudo install rpmrebuild
$ rpmrebuild --change-spec-requires='sed -e "s/libatomic1/libatomic/"' --package skypeforlinux-64.rpm

Self-signed certificates can be made with no costs, and without public CA involvement. There are multiple free tools available for creating such certificates. The following examples will show how to use OpenSSL on linux machine, and RouterOS CLI to generate and sign your own certificates.

RouterOS example:

First we need to make our own CA who will sign the cerificates

/certificate
add name=ca-template common-name=myCa key-usage=key-cert-sign,crl-sign
sign ca-template name=myCa

/certificate

add name=ca-template common-name=myCa key-usage=key-cert-sign,crl-sign

sign ca-template name=myCa

Now create a certificate for Hotspot

/certificate
add name=Hotspot-template common-name=Hotspot
sign Hotspot-template ca=myCa name=Hotspot

/certificate

add name=Hotspot-template common-name=Hotspot

sign Hotspot-template ca=myCa name=Hotspot

Make server certificate trusted

set [find name=Hotspot] trusted=yes

1	set [find name=Hotspot] trusted=yes

Всем привет!

Открываю новый сайт прежде всего для того, чтобы централизовать информацию по проектам, которыми занимался за время работы в разных компаниях в одном месте и наконец-таки избавиться от записулек, напоминалок и заметок.

В основном это IT направление.

И так, hello world!

p.s. Посты буду опубликовывать на двух языках. А иногда и смежно. Любой ИТишник знает, что это absolutely normal. 🙂
