[19:49] <irc_user_xubuntu> Hello there, rapid question: How can I check the xubuntu ISO using the $ gpg –verify SHA256SUMS.gpg SHA256SUMS, please
[19:53] <irc_user_xubuntu> Well, that is because I cannot find the release repository with the SHA256SUMS and SHA256SUMS.gpg for xubuntu as https://releases.ubuntu.com/20.04/, for example.
[19:53] <irc_user_xubuntu> Could any one help me please? 
[19:53] <diogenes_> !checksum
[19:54] <diogenes_> also the files are here: https://cdimage.ubuntu.com/xubuntu/releases/
[19:58] <irc_user_xubuntu> Well done diogenes_, your last answer is exactly what I was looking for!
[19:58] <irc_user_xubuntu> Thank you so much dude!
[19:59] <irc_user_xubuntu> Have I nice day.
[19:59] <irc_user_xubuntu> Bye.
