    How to enable access to newly installed USB stick ?

    I really appreciate all your contributions, with an exception of comment on my "attitude" and other comment which IMHO belong to social media and not in forum like this. There is no need starting with " turn the power on..." but it would be nice to comment / explain stuff. From my...

    How to enable access to newly installed USB stick ?

    OK, let's forget the chown... and RE-READ the OP , including the part about gparted it is the IDE who wants to save the current program the device , USB in this case in not know until the IDE needs to save it there is no "mkdir" - it is hidden in IDE... Yes . lsusb shows it , the ownership is...

    How to enable access to newly installed USB stick ?

    I can use gparted to add / format etc. new USB stick. I used to use "disks" to mount it, but having an issues installing in .... BUT - when I use C++ IDE to build an new program on this USB I cannot "create directory" . I must be missing permissions and perhaps ownership... Is there a...

    21.04 won't start from grub

    OK, no need to cry over spilled milk - I am after a solution - rehashing / speculating what MAY have caused the problem is now pointless. But I need to have a better reason then just "try it , it won't hurt. As I said before , I am paranoid. I rather live with this than risk loosing access...

    21.04 won't start from grub

    Well, I really appreciate you sticking with the problem. I tried to clean-up a decent size partition to do the backup. gparted did not cooperate - would not let me delete "busy" partition. I ended up attaching my first backup to another , large , folder. I did follow the instruction and...

    Ubuntu desktop locking up

    Would it be possible for somebody JUST to confirm this? On Ubuntu 21.04 when I LEFT click on the icon on the LEFT of the desktop the PC locks up - only recovery is to power down. And I am NOT talking about RIGHT click - thet works as expected.

    21.04 won't start from grub

    Well it is a same old story - how do you "backup" data from different application? I will not post a list of them... So far my "solution" is to have "important files " on RAID and just manually copy entire folders, almost daily. And again , as in this case - how do you backup entire OS so when...

    21.04 won't start from grub

    I am puzzled by daily Ubuntu updates and still getting "system problem " on start-up. Here is my best recollection what is happening. I chose to update /upgrade ONE on my multitboot OS. I got impatient with the snail pace of the upgrade so I "sudo reboot -f" Now when I select in "grub" my...

    Implementing EAGLE on Ubuntu 21.04

    to me this is a big issue with googling and finding ancient info and passing it as current. I found very "autoritative opinions " about EAGEL does not do spice.... I really believe that every post should be visibly dated or google should have an option to sort the finds by date But that is...
