I have a large amount of password protected files in a zip archive that I created in Ubuntu 18.04 or maybe even earlier. In Ubuntu 18.04 LTS I can extract the password protected files from the zip archive without any problems.
Now I have installed Ubuntu 20.04 on a new partition, but when I boot on that and try to extract files from the password protected zip archive I get an error message. This is not very reassuring!
It fails whether I just click on the file (inside the zip archive) or I right-click it and choose 'extract' from the menu. In the latter case it DOES ask me for a password, but still fails reading the file.
In both cases the error message is: "An error occurred while extracting files". Any help would be much appreciated. Thank you.
NB: An alternative would be to extract all files in 18.04 and try to password protect them in a new archive in 20.04. Could that be done?
