I've looked over dozens of similar questions, nothing has jumped out as applicable. ls returns "arduino-1.8.3" {lower case} ron@ron:~$ cd (or sudo cd) /arduino-1.8.3 returns No Such File or Directory"
In the directory is uninstall.sh but it won't run from the file manager.
I realize I'm probably missing something obvious to an experienced user which I'm not.
TIA

lsshows a directoryarduino-1.8.3in the current directory, then you can enter it usingcd arduino-1.8.3orcd ./arduino-1.8.3but notcd /arduino-1.8.3since that means a location in the/directory - not the current one. – steeldriver Jul 23 '17 at 21:36
