A few days ago was able to install libreoffice base with software boutique. Using Ubuntu-mate 20.04 on HP pavilion 23 and Windows 8.1. No errors found when booted to live install of Ubuntu-mate. But today when I tried to install libreoffice base get error failed to download package files. Failed to fetch “http://-archive.Ubuntu.com/Ubuntu/pool/-base-“. Am able to install other applications in software boutique such as BleachBit etc. tried “sudo apt-get update”. Then tried software boutique again with no error installing base. But then when I try to start any office application get error Ubuntu 20.04 has experienced an internal error. Package libreoffice-core 1:6.4.6-0ubuntu0.20.04.1. Soft ice.bin crashed with SIGABRT in uno_type_any_assign().
Checking further the file Software boutique is trying to fetch does not exist: "http://archive.ubuntu.com/ubuntu/pool/universe/libr/libreoffice/libreoffice-base-drivers_6.4.4-0ubuntu0.20.04.1_amd64.deb". There is a similar file ... drivers_6.4.6-0 .... but if I download that file and try to install get message that "An older version is available in a software channel ... are recommended to install version from the software channel ..."
