Sudo password?

[Mojomagi]

Trying to install express vpn and I noticed my log in code works to open the terminal but when asked again after sudo it says incorrect password. Looking online I also tried ubuntu and ubports which didn't work. I also checked the telegram faq. Sorry for the noob question and sorry if this is not in the correct thread. I don't want to get locked out haha. I have a screen shot of the teminal comands used with the warning of the 3rd attempted incorect PW but I dont see a way to post here. Cheers o/

@Mojomagi Sudo password should be your lockscreen password and the one you used opening the Terminal app. Not sure what's happening to yours though. Changing password via terminal commands is not recommended BTW.

The four digit pin gets me into the terminal but says incorrect password after initiating the sudo command. I've tried several times hoping I fat fingered a key but no it doesn't work. Also I am not trying to change the PW just doesn't seem that I know the password. Ubuntu T installed without issues and has only been on the phone a few days

@Mojomagi that is really weird, since as @kugiigi said, your user pin is also the password you enter in the consule wjem prompted by sudo.

If you do: sudo ls, Do you also get 'invalid password' after entering your pin?

@arubislander
phablet@ubuntu-phablet:~$ sudo ls

No PW for ls but I'm not sure what you had there cause it looks more like a 1 not an lowercase "L".

@arubislander It may have worked this time but I came yo with an error I will have to look into.

May its just a bit picky and I will try a few more commands other than this one till I look at it more. Thanks !!

Ok mark this as closed please. Seems the numbers might be touchy or I wasn't doing something corcorrectly. Here this shows the PW worked.
Thanks everyone!!

@Mojomagi, yes it was an -l-, but in a monospaced font to signify it is code, and not part of the text. Anyhow, it was to check that you can successfully enter your password with sudo. The fact that you did not need to enter you password that time only means it was successfully entered earlier, for a previous command with sudo.

As you yourself realized, there was not a configuration error, just an input error.

@Mojomagi Yes, installing 'random' packages on UT will not work ootb, because of the read-only filesystem. Does ExpressVPN have any way to install their software for just the current user in the user's home directory?

[Mojomagi]

@arubislander I will be honest I'm not sure, I'm really new at this. I saw that UT supports many ubuntu 20.04 programs so I thought I would try to install express vpn since I have a subscription. This is a second phone to me so if I make mistakes I can always start over and learn from what I did wrong. My research led me to think maby the drive wasn't mounted correctly but I haven't had time to check yet. Its very possible express vpn wont work on UT but I will look into the other installation method you spoke of. Thanks!!
