How to always get the latest version of Bleachbit with wget in bash?
To get latest version of BleachBit (for Ubuntu 20.04) we can use the following commands:
wget -c https://download.bleachbit.org/bleachbit_4.4.0-0_all_ubuntu2004.deb -O bleachbit.deb
dpkg -i bleachbit.deb
If we install it from the official Ubuntu repository (with apt-get bleachbit), an older version is installed, which contains installation errors. And according to the creators of this tool:
Ubuntu has a "no rolling release" policy, so the Ubuntu repository will not update with the recent versions
Since this tool is regularly updated, I would like to always download the latest version. So I did this bash, but it doesn't work:
lastbleachbit=$(wget -O - https://www.bleachbit.org/download/ | grep -Po '/download/file/([^"]+)' | grep ubuntu2004 | sort -u)
wget -c https://www.bleachbit.org"$lastbleachbit" -O bleachbit.deb
dpkg -i bleachbit.deb
Output variable:
lastmintstick=$(wget -O - http://packages.linuxmint.com/pool/main/m/mintstick/ | grep -Po 'href=".*?"' | sed -r 's:href\="(.*)":\1:' | grep ".deb" | sort | tail -1)

What did I do wrong?
Solution 1:
You're missing /linux.
$ lastbleachbit=$(wget --quiet -O - https://www.bleachbit.org/download/linux | grep -Po '/download/file/([^"]+)' | grep ubuntu2004 | sort -u)
$ echo $lastbleachbit
/download/file/t?file=bleachbit_4.4.0-0_all_ubuntu2004.deb
With my limited grep knowledge, I managed to get it working.
$ lastbleachbit=$(wget --quiet -O - https://www.bleachbit.org/download/linux | grep -Po '(?<=file=).*(?=">)' | grep ubuntu2004 | sort -u)
$ echo $lastbleachbit
bleachbit_4.4.0-0_all_ubuntu2004.deb
When you download it.
$ wget "https://download.bleachbit.org/${lastbleachbit}"

I think this should work as long the download page keep embedding link containing .deb file, though I don't know for how long as I never use bleachbit.
