This problem was with Linux Mint Xfce 20.0 -----> Still learning about these PPA’s.
I went to install s/w that support Western Digital’s ‘My Passport’ external HDD under Mint 20 and got an error. The same procedure worked on Mint 18 and Mint 19. I just used it with MX 19 and it works there also. Here is the command and the output from it.
sudo apt-get install python-pip python-dev lsscsi
[sudo] password for easyt50:
Reading package lists… Done
Building dependency tree
Reading state information… Done
Note, selecting ‘python-dev-is-python2’ instead of ‘python-dev’
E: Unable to locate package python-pip
I don’t even know what ppa it is. Does the ppa have to wait until Mint OK’s it library? Like I said, in Mint 19 and MX 19 the command worked. So, I’m confused. Why does the command work sometimes and not other times?
