Ubuntu 22.04.2で，apt keyの警告がでてた

とかいわれてたので解消．
 apt-key list
としたら，
 ...

とのことなので，
 sudo mkdir -p /usr/local/share/keyrings
とかして格納先を作って
 sudo apt-key export 038651BD | sudo gpg --dearmour -o /usr/local/share/keyrings/slack.gpg
 sudo apt-key export DF7587C3 | sudo gpg --dearmour -o /usr/local/share/keyrings/skype.gpg
と鍵を格納．
/etc/apt/sources.list.d/skype-stable.list と /etc/apt/sources.list.d/slack.list を，それぞれ，
 deb [arch=amd64 signed-by=/usr/local/share/keyrings/skype.gpg] https://repo.skype.com/deb stable main
と
 # You may comment out this entry, but any other modifications may be lost.
 #Edeb https://packagecloud.io/slacktechnologies/slack/debian/ jessie main
 deb [signed-by=/usr/local/share/keyrings/slack.gpg] https://packagecloud.io/slacktechnologies/slack/debian/ jessie main
